ESlint Error Install from Command Line

Question

I get the following error installing eslint:

npm ERR! Darwin 15.4.0
npm ERR! argv "/usr/local/bin/node" "/usr/local/bin/npm" "install" "-g" "eslint"
npm ERR! node v5.5.0

npm ERR! Please try running this command again as root/Administrator.

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

I have not been able to figure out how to install eslint and also get this line:

eslint --init to run to create the .eslintrc file

Answer 1

It looks like you're trying to install globally while your user doesn't have access to the global node_modules folder. You can try installing it as root or chown '/usr/local/lib/node_modules'.

Install as root -

    sudo npm install -g eslint

Chown -

    chown user:group /usr/local/lib/node_modules
    npm install -g eslint

You can also change permissions to /usr/local/lib/node_modules to allow your user access using chmod.

Edit: Try the solution in the answer here "Permission Denied" when trying to install ESlint on OSX globally

Add this to ~/.npmrc:

prefix = ${HOME}/.npm-packages https://github.com/sindresorhus/guides/blob/master/npm-global-without-sudo.md You also have to add ${HOME}/.npm-packages/.bin to your PATH so that your shell knows where to look up the globally installed scripts.

Answer 2

If you're getting eslint: command not found try:

./node_modules/.bin/eslint --init

Answer 3

Try

npm install eslint --save-dev and then eslint --init.

Let me know if you face any issues.
