Question

I am trying to get my node environment set up on a new Ubuntu 12 04 instance  with Node 0 8 14 already installed  but I ran into problems when I try to run npm install  So when I try npm install  it says that I need to run it as root or adminisrator   Error  EACCES  mkdir   usr local lib node modules coffee-script  npm ERR      Error  EACCES  mkdir   usr local lib node modules coffee-script   npm ERR    errno  3  npm ERR    code   EACCES   npm ERR    path    usr local lib node modules coffee-script   npm ERR    fstream type   Directory   npm ERR    fstream path    usr local lib node modules coffee-script   npm ERR    fstream class   DirWriter   npm ERR    fstream stack   npm ERR        DirWriter  create                   usr local lib node modules npm node modules fstream lib dir-writer js 36 23    npm ERR         usr local lib node modules npm node modules mkdirp index js 37 53   npm ERR        Object oncomplete  fs js 297 15       npm ERR   npm ERR  Please try running this command again as root Administrator    But when try to run it as sudo  it says the following   npm WARN cannot run in wd PackNodeDev 0 0 1-166 npm install -g coffee-script node-gyp  wd  home ubuntu PackNode    In my package json  it contains the following scripts    scripts          preinstall    npm install -g coffee-script node-gyp        start    node server js        test    mocha --require should --compilers coffee coffee-script --colors        The rest of devdependencies are valid since I have been installing it all right on my own machine  Mac  Does anyone have a clue why this is happening

OP here  I have learned a lot more about node since I first asked this question  Though Dmitry s answer was very helpful  what ultimately did it for me is to install node with the correct permissions   I highly recommend not installing node using any package managers  but rather to compile it yourself so that it resides in a local directory with normal permissions   This article provides a very clear step-by-step instruction of how to do so   https   www digitalocean com community tutorials how-to-install-an-upstream-version-of-node-js-on-ubuntu-12-04

I have experienced the same problem when trying to publish my nodejs app in a private server running CentOs using root user  The same error is fired by  postinstall      node modules bower bin bower install  in my package json file so the only solution that was working for me is to use both options to avoid the error   1  use --allow-root option for bower install command   postinstall      node modules bower bin bower --allow-root install    2  use --unsafe-perm option for npm install command  npm install --unsafe-perm

I fixed this by changing the ownership of  usr local and   Users user-name like so   sudo chown -R my name  usr local  This allowed me to do everything without sudo

The documentation says  also here       If npm was invoked with root privileges  then it will change the uid to the user account or uid specified by the user config  which defaults to nobody  Set the unsafe-perm flag to run scripts with root privileges    Your options are    Run npm install with the --unsafe-perm flag    sudo  npm install --unsafe-perm  Add the unsafe-perm flag to your package json    config          unsafe-perm  true    Don t use the preinstall script to install global modules  install them separately and then run the regular npm install without root privileges   sudo npm install -g coffee-script node-gyp npm install      Related    package json for global module installation

The only thing that worked for me was adding a  npmrc file containing   unsafe-perm   true   Adding the same config to package json didn t have any effect

For Docker      Alexander Mills answer - just to make it easier to find  RUN npm set unsafe-perm true
