npm throws EACCES error on installation of Angular CLI

问题

I am unable to install Angular Cli globally through npm. I keep getting this error when I run npm install -g @angular/cli on macOS:

npm ERR! node v6.9.2
npm ERR! npm  v3.10.9
npm ERR! path /usr/local/lib/node_modules

When you use npm install -g on any platform and you get EACCES, you are writing to a directory for which you do not have write permission.

Some may recommend using sudo, but this will lead to more problems in the future. The npm documentation provides steps to fix this.

I highly recommend option 3, using Homebrew to install Node.

Try using this: 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

Test installing package globally without using sudo. Now run npm install -g @angular/cli it should work.

回答3:

WARNING: Check that $(npm config get prefix) does not point to /usr by typing echo $(npm config get prefix)

I solved like that

sudo chown -R $(whoami) $(npm config get prefix)/{lib/node_modules,bin,share}

Worked for me

回答4:

create a directory for global installations:

mkdir ~/.npm-global
Configure npm to use the new directory path:

npm config set prefix '~/.npm-global'
create a ~/.profile file and add this line:

export PATH=~/.npm-global/bin:$PATH
update your system variables:

source ~/.profile

I fixed the issue by running

sudo npm install -g @angular/cli

After prompting for password enter it.

Then you will be able to install.

The answer by Ayush is what I tried at first. Yet the problem persisted. Maybe I didn't do all the steps correctly , I am not sure. So again I looked up Google and found this link https://github.com/angular/angular-cli/issues/7735#issuecomment-345546822. There are two ways to go about solving it. Luckily the first way worked for me. The step that might have made a difference may be compared to what Ayush mentioned above in the answers:

$ echo -e "export PATH=$(npm prefix -g)/bin:$PATH" >> ~/.bashrc 
$ source ~/.bashrc

I am using Ubuntu though! Anyways it is solved now. :)

Hello Please Follow my guide to install angular 4 from the cli without any permission issues:

Install the angular-cli globally

sudo npm install -g @angular/cli

Create a new project

ng new my-app --skip-install

Serve the application

sudo chown <username> -R my-app
cd my-app
mkdir node_modules
chmod a+w node_modules
npm install
ng serve --open

Important Note: My answer has vulnerability issues. Giving permissions as root. Use it only after analyzing the effect on your system.

After using

sudo npm install -g PACKAGE-NAME --unsafe-perm=true --allow-root

I still had issues creating a project with the CLI. these commands, allowing permissions, fixed it:

sudo chown -R $USER:$GROUP ~/.npm

sudo chown -R $USER:$GROUP ~/.config

Run this command for centos user:

npm install npm@latest -g

it worked for me!!
