@angular-cli install fails with deprecated request

问题:

After updating node.js and npm to current LTS:

node -v
v12.16.0

npm -v
6.13.4

When I'm trying to install @angular-cli following the steps in the documentation, running npm install -g @angular/cli in the terminal stops the installation and the console output is:

npm install -g @angular/cli
npm WARN deprecated request@2.88.2: request has been deprecated, see https://github.com/request/request/issues/3142
/Users/user/.npm-global/bin/ng -> /USERS/USER/.npm-global/lib/node_modules/@angular/cli/bin/ng

> @angular/cli@9.0.2 postinstall /USERS/USER/.npm-global/lib/node_modules/@angular/cli
> node ./bin/postinstall/script.js

+ @angular/cli@9.0.2
updated 1 package in 12.202s

And in this case, ng new project-name yields -bash: ng: command not found. Any help would be very welcome as I have a big project coming up. Thanks all.

回答1:

The issue you are experiencing has noting to do with npm warning you see in console ref. It is seems more likely a problem with permissions on your machine or NodeJS installation issue or both.

I would recommend to remove your NodeJS installation completely at first and then install NVM to manage your NodeJS instances:

• Mac/Linux: https://github.com/nvm-sh/nvm
• Windows:https://github.com/coreybutler/nvm-windows

Once you done installing NVM try to install Angular CLI:

npm install @angular/cli -g

Hope it helps!

UPDATE: Also you can check this issue

I removed "node_modules" folder & "package-lock.json" file and then execute following 2 commands:

npm init

npm install

And then, it worked properly.

回答3:

I tried cleaning cache and it worked for me.

npm cache clean --force

回答4:

Uninstalling and installing angular cli works fine for me.

回答5:

$brew install angular-cli

Installed angular9.0.3(stable) This depends on node13.08.0

回答6:

I faced same issue in my Angular 9 project, I just copy pasted node_modules folder from my old angular project, I worked fine, Please try this way if nothing worked out. but you will get the same issue if you do npm install, pls don't do.

As stated in the documentation, using a Windows 10 machine, to install Angular CLI in a machine with NodeJS and npm package manager

node -v
# v12.16.0

npm -v
# 6.13.4

the first time running

npm install -g @angular/cli

got similar message to yours

npm WARN deprecated request@2.88.2: request has been deprecated, see https://github.com/request/request/issues/3142

C:\Users\tiago\AppData\Roaming\npm\ng -> C:\Users\tiago\AppData\Roaming\npm\node_modules\@angular\cli\bin\ng

> @angular/cli@10.0.0 postinstall C:\Users\tiago\AppData\Roaming\npm\node_modules\@angular\cli
> node ./bin/postinstall/script.js

+ @angular/cli@10.0.0
added 269 packages from 206 contributors in 97.901s

Then, when running a second time, the message matched yours (notice the last line now doesn't say added 269 packages; instead, updated 1 package).

npm WARN deprecated request@2.88.2: request has been deprecated, see https://github.com/request/request/issues/3142
C:\Users\tiago\AppData\Roaming\npm\ng -> C:\Users\tiago\AppData\Roaming\npm\node_modules\@angular\cli\bin\ng

> @angular/cli@10.0.0 postinstall C:\Users\tiago\AppData\Roaming\npm\node_modules\@angular\cli
> node ./bin/postinstall/script.js

+ @angular/cli@10.0.0
updated 1 package in 8.691s

If I then type

ng --version

I didn't get an error like you. Instead, got the following result

     _                      _                 ____ _     ___
    / \   _ __   __ _ _   _| | __ _ _ __     / ___| |   |_ _|

                |___/


Angular CLI: 10.0.0
Node: 12.16.0
OS: win32 x64

Angular:
...
Ivy Workspace:

Package                      Version
------------------------------------------------------
@angular-devkit/architect    0.1000.0
@angular-devkit/core         10.0.0
@angular-devkit/schematics   10.0.0
@schematics/angular          10.0.0
@schematics/update           0.1000.0
rxjs                         6.5.5

which shows that it actually didn't fail but got Angular CLI installed.

In fact, when I run (with cd to C:/Users/tiago/Desktop/angular)

ng new my-app

The my-app is created

and can be served (with cd to my-app)

ng serve --open 

As I can see the following page, this means the installation and setup was successful.

---

So, as per your case with -bash: ng: command not found, this may mean NodeJS wasn't installed properly (I would reinstall it). If that doesn't solve, I've seen another solution to that problem before; simply follow the next steps

1. Remove Node from your system
2. Install NVM
3. Install Node via NVM: nvm install stable
4. Run npm install -g @angular/cli

回答8:

npm cache clean --force

npm install -g @angular/cli

npm install mkdirp

npm cache verify

close the terminal and open it again

ng new newApp

it will work for this issue....

Happy Coding

回答9:

In case if you are facing issue in Windows machine.

Just mention cli version along with the command.

npm i @angular/cli@8.1.0

This worked for me.

Further , you might need to set path variable if getting below issue

'ng' is not recognized as an internal or external command, operable program or batch file

回答10:

Unfortunately, Request package was deprecated. and that according to Mikeal Rogers (creator of request) read this link

and for more information, you can read this article

回答11:

The package request is now fully deprecated. So that will probably take a while to change. I think the solution would be for angular cli to release a new version that is not reliant upon request.
