change your file permissions .. like this

first check who owns the directory

ls -la /usr/local/lib/node_modules

it is denying access because the node_module folder is owned by root

drwxr-xr-x   3 root    wheel  102 Jun 24 23:24 node_modules

so this needs to be changed by changing root to your user but first run command below to check your current user How do I get the name of the active user via the command line in OS X?

id -un

OR

whoami

then change owner

sudo chown -R [owner]:[owner] /usr/local/lib/node_modules

OR

sudo chown -R ownerName: /usr/local/lib/node_modules

OR

sudo chown -R $USER /usr/local/lib/node_modules

To minimize the chance of permissions errors, you can configure npm to use a different directory. In this example, you will create and use a hidden directory in your home directory.

Back up your computer. On the command line, in your home directory, create a directory for global installations: mkdir ~/.npm-global Configure npm to use the new directory path: npm config set prefix '~/.npm-global' In your preferred text editor, open or create a ~/.profile file and add this line: export PATH=~/.npm-global/bin:$PATH On the command line, update your system variables: source ~/.profile To test your new configuration, install a package globally without using sudo

回答3:

All you need to do is to add USER to the owner of /local/lib

sudo chown -R $USER /usr/local/lib

回答4:

try appending sudo before whatever command you are trying.

like this : sudo npm install

Using sudo with a command in Linux/UNIX generally elevates your permissions to superuser levels. In Windows, the superuser account is usually called 'Administrator.' In Linux/Unix the superuser account is generally named 'root'.

The root user has permission to access, modify or delete almost any file on your computer. Normal user accounts can access, modify or delete many fewer files. The restrictions on a normal account protect your computer from unauthorized or harmful programs or users. Some processes require you to perform actions on files or folders you don't normally have permissions to access. Installing a program that everyone can access is one of these actions.

In your case, running the installation command with sudo gives you the permissions of the superuser, and allows you to modify files that your normal user doesn't have permission to modify.

While installing global packages in ubuntu, you need special write permissions as you are writing to the usr/bin folder. It is for security reasons. So, everytime you install a global package, use:

sudo npm install -g [package-name]

For your specific case, it will be:

sudo npm install -g typescript

I tried the solution of the answer given by @okanda but it didn't work for me.

However it worked perfectly when I did it for several folders like mentioned in this thread: https://github.com/angular/angular-cli/issues/9676#issuecomment-464857493

sudo chown -R $USER /usr/local/lib/node_modules/
sudo chown -R $USER /usr/local/bin/
sudo chown -R $USER /usr/local/share/

I was trying to install react expo and apart from sudo I had to add --unsafe-perm

like this. This resolves my Issue

sudo npm install -g expo-cli --unsafe-perm

回答8:

It looks like you're running into permission issues. If you are installing npm-packages then it might possible that you are getting an EACCES error when trying to install a package globally. This means you do not have permission to write to the directories npm uses to store global packages and commands.

Try running commands: sudo chmod u+x -R 775 ~/.npm and sudo chown $USER -R ~/.npm or you can just run any npm command with sudo, that should get resolve your issue.

If you are installing an npm-package locally, then you should be in your local project directory and can try running sudo npm install <pkg-name> command to install required package. the purpose of using sudo is that it will change your owner permissions so you can make your current user authorized to run npm commands.

I'd recommend you to take a look at https://docs.npmjs.com/getting-started/fixing-npm-permissions

回答9:

Be careful with all responses that change the owner of all directories under /usr/local Basically, don't mess the linux system!!!

I think that the best way is to use your own folder to locate all global packages: https://www.competa.com/blog/how-to-run-npm-without-sudo/

回答10:

Use this command to install npm as the sudo user:

sudo npm install -g create-react-app 

instead of npm install -g create-react-a pp.

回答11:

If you are facing this issue on you Mac. Follow these steps

First checking who is owner of this file by using below command

  ls -la /usr/local/lib/node_modules

you will find some file like below one of them is below

drwxr-xr-x 3 root wheel 768 May 29 02:21 node_modules

have you notice that above file is own by root, for make changes inside for you need to change owner ship of path.

you can use check who is current user by this command

  id -un                    (in my case user is yamsol)

and then you can change by calling this command (just replace your user name with ownerName)

  sudo chown -R ownerName: /usr/local/lib/node_modules

in my case as you know user is "yamsol" i will call this command in this way

  sudo chown -R yamsol: /usr/local/lib/node_modules

thats it.

Seems like you tried to install a npm package globally rather than locally, as the man npm install describes:

The -g or --global argument will cause npm to install the package globally rather than locally.

Generally, when you are setting up a npm project (among many others that you could have), it's not a good idea to install packages on Node.js global modules (/usr/local/lib/node_modules), as your the debug log suggested.

Instead of using -g, use --save, which will automatically save the package as a dependency for your package.json file:

Like this:

$ npm install express-generator --save

$ cat package.json 
{
  "name": "first_app_generator",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
},
  "author": "ivanleoncz",
  "license": "MIT",
  "dependencies": {
    "express-generator": "^4.16.0"
  }
}

But as the other answers mentioned, if you're going to use -g, you have to use sudo (if your user has sudo privileges: see /etc/sudoers) when performing npm install express-generator -g, but indeed, it's not a good idea, possibly causing permission problems.

NOTICE

There are instructions for installing express-generator with -g option, in order to have the script express-cli.js available on the system path, but you can use the locally installed script as well, located at the node_modules if your npm project:

$ ./node_modules/express-generator/bin/express-cli.js --view=pug myapp

If a message like /usr/bin/env: ‘node’: No such file or directory shows up, install nodejs-legacy (Debian/Ubuntu)

IMHO, using -g (also using sudo) is like hic sunt dracones, if you are unsure of the consequences.

For further information:

• Creating NPM Package (npm init)
• Express.js Generator

回答13:

Simply you can change the owner or just use sudo before you command like this

sudo chown -R [owner]:[owner] /usr/local/lib/node_modules (change owner)

or

sudo npm install -g json-server

that's it.

I was able to fix the issue using the following in mac.

sudo npm install -g @aws-amplify/cli --unsafe-perm=true

Fix : Install with root permissions

sudo npm install <package_name> -g

回答16:

You need the permission of superuser levels to install React. In Linux/Unix the superuser account is generally named 'root'.

To get superuser privilege just run the following command on your terminal:

sudo -i

and then simply run the command to install React:

npm install -g create-react-app

However, the reactjs team encourages us to use the following command instead of installing a global package.

npx create-react-app app_name

You can install npm through Node version manager or a Node installer. In the docs it stated:

We do not recommend using a Node installer, since the Node installation process installs npm in a directory with local permissions and can cause permissions errors when you run npm packages globally.

Since you have the permission error, you probably installed npm through a Node installer and now you need to reinstalled it with a nvm (node version manager).

Luckily, this is very simple. You do not even need to remove your current version of npm or Node.js.

All you need to do is

1. Install nvm. For OSX or Linux Node use:

   curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.2/install.sh | bash
   

   This creates a nvm folder in your home directory.

Then

2. Install npm and node.js through nvm. To do so, just call

   nvm install stable
   

Now you can install your package globally without using sudo or changing the owner of node_modules in usr folder.

回答18:

Helped only this:

sudo chown -R ownerName: /usr/local/lib/node_modules

回答19:

For nvm users

sudo chown -R $USER /home/bereket/.nvm/versions/node/v8.9.1/lib/node_modules 

and

sudo chown -R $USER /usr/local/lib/node_modules/

replace v8.9.1 with your node version you are using.

回答20:

I have used sudo, but it didnt solve the problem, I have fixed the issue by changing the node_modules folder permission,

sudo chmod -R 777 node_modules

If you want you can replace 777 with any other code if you dont set the permission for all user/group.

I was able to get rid of this issue by installing nvm, then setting node to latest version.

1. Install nvm using curl (for latest version go to nvm.sh)

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.34.0/install.sh | bash

2. List available node versions

nvm ls

v10.12.0
default -> v10.12 (-> v10.12.0)
node -> stable (-> v10.12.0) (default)
stable -> 10.12 (-> v10.12.0)
…

3. Choose which version of node to use

nvm use v10.12

nvm is not compatible with the npm config "prefix" option: currently set to ""

4. Run this to unset the option:

nvm use --delete-prefix v10.12.0

After following the commands above, you will be able to install react/angular in Ubuntu.

After long research i understood that nothing is required for mac OS to install angular cli just use sudo npm install -g @angular/cli your terminal will prompt password enter your password it will proceed to install cli. It worked for me.
