Error: EACCES when creating new Ember project

Question

I just installed Linux Mint (version 17.2) and I'm trying to install Ember. Everything seemed to go fine, but I'm getting this error when I run ember new testProject .

  create vendor/.gitkeep
EACCES, mkdir '/home/mkm/.npm/mkdirp/0.4.2'
Error: EACCES, mkdir '/home/mkm/.npm/mkdirp/0.4.2'
    at Error (native)

Per a recommendation in the Ember Documentation I used this guide to install Node.js and NPM. Some of what I've read suggest the issue is nodejs was installed with sudo, but apt-get failed when I didn't use sudo.

I attempted to run the new project anyway. bower install completed successfully. But ember serve failed with Cannot find module 'chalk' .

--Version Info

$ ember --version
version: 1.13.8
Could not find watchman, falling back to NodeWatcher for file system events.

Answer 1

The only command that was needed to run with sudo for me was:

npm install

I suggest you delete node_modules/ in your project directory completely, then run:

sudo npm install

You can also add option --verbose to see if everything is correctly installing and installation isn't stuck.

You could also change permissions for .npm directory to avoid some problems like that in future:

sudo chmod 777 -R /home/mkm/.npm

Answer 2

You can use following commands to install and use npm without sudo:

wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.25.4/install.sh | NVM_DIR="/home/your-user-name/.nvm" bash
export NVM_DIR="/home/your-user-name/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh"

nvm install 0.12
nvm alias default 0.12

npm install -g ember-cli
npm install -g bower
npm install -g phantomjs

Here is a link to nvm repository with latest version and documentation: https://github.com/creationix/nvm
