nodemon not working: -bash: nodemon: command not f

问题:

I'm on a Mac running El Capitan. I have node v5.6.0 and npm v3.6.0. When I try to run nodemon, I get:

-bash: nodemon: command not found

I thought this may mean that I didn't have nodemon installed, so when I tried to install it using...

sudo npm intall -g nodemon

...I get this:

npm ERR! Darwin 15.2.0
npm ERR! argv "/usr/local/bin/node" "/usr/local/bin/npm" "install" "-g"     "nodemon"
npm ERR! node v5.6.0

npm ERR! code EEXIST

npm ERR! Move it away, and try again.

npm ERR! Please include the following file with any support request:

If it makes a difference, I'm trying to run nodemon on a project that uses Express v4.13.1

Thanks for any help you can offer!

I tried the following, and none worked:

npm uninstall nodemon

sudo npm uninstall -g nodemon

What did work was:

sudo npm install -g --force nodemon

回答2:

If you want to run it locally instead of globally, you can run it from your node_modules:

npx nodemon

I ran into the same problem since I had changed my global path of npm packages before.

Here's how I fixed it :

When I installed nodemon using : npm install nodemon -g --save , my path for the global npm packages was not present in the PATH variable .

If you just add it to the $PATH variable it will get fixed.

Edit the ~/.bashrc file in your home folder and add this line :-

export PATH=$PATH:~/npm

Here "npm" is the path to my global npm packages . Replace it with the global path in your system

I have also faced the same issue. then following command worked for me..

sudo npm install -g nodemon

回答5:

I had the same exact problem, expect for Windows OS.

For me, running

npm install -g nodemon --save-dev

(note the -g) worked.

Maybe somebody else who has this problem on Windows will have the same solution.

回答6:

In macOS, I fixed this error by installing nodemon globally

npm install -g nodemon --save-dev 

and by adding the npm path to the bash_profile file. First, open bash_profile in nano by using the following command,

nano ~/.bash_profile

Second, add the following two lines to the bash_profile file (I use comments "##" which makes it bash_profile more readable)

## npm
export PATH=$PATH:~/npm

回答7:

sudo su

then

npm install nodemon 

worked for me

Make sure you own root directory for npm so you don't get any errors when you install global packages without using sudo.

procedures:- in root directory

sudo chown -R yourUsername /usr/local/lib/node_modules
sudo chown -R yourUsername /usr/local/bin/
sudo chown -R yourUsername /usr/local/share/

So now with

npm i npm -g 

you get no errors and no use of sudo here. but if you still get errors confirm node_modules is owned again

/usr/local/lib/

and make sure you own everything

ls -la

now

npm i -g nodemon

will work!
