Just prepend sudo to the beginning of your command  As stated before  an installation runs some scripts that might be dangerous but I saw installing globally helps a lot and is way simpler   Run sudo npm install -g less

This will definitely help  Answer by npm itself   https   docs npmjs com getting-started fixing-npm-permissions  Below is extracted from the URL for your convenience     Option 1  Change the permission to npm s default directory   Find the path to npm s directory   npm config get prefix   For many systems  this will be  usr local      WARNING  If the displayed path is just  usr  switch to Option 2 or you   will mess up your permissions     Change the owner of npm s directories to the name of the current user  your username     sudo chown -R   whoami    npm config get prefix   lib node modules bin share    This changes the permissions of the sub-folders used by npm and some other tools  lib node modules  bin  and share      Option 2  Change npm s default directory to another directory   Make a directory for global installations   mkdir    npm-global Configure npm to use the new directory path   npm config set prefix     npm-global  Open or create a    profile file and add this line   export PATH    npm-global bin  PATH Back on the command line  update your system variables   source    profile   Test  Download a package globally without using sudo    npm install -g jshint    Instead of steps 2-4  you can use the corresponding ENV variable  e g  if you don t want to modify    profile    NPM CONFIG PREFIX    npm-global    Option 3  Use a package manager that takes care of this for you  If you re doing a fresh install of Node on Mac OS  you can avoid this problem altogether by using the Homebrew package manager  Homebrew sets things up out of the box with the correct permissions   brew install node

I kept having this problem because windows was setting my node modules folder to Readonly   Make sure you uncheck this

In my case i needed to update the npm version from  5 3 0   5 4 2    Before i could use this -- npm i -g npm     i needed to run two commands which perfectly solved my problem  It is highly likely that it will even solve your problem   Step 1  sudo chown -R  USER  usr local  Step 2  npm install -g cordova ionic  After this you should  update your npm to latest version  Step 3   npm i -g npm  Then you are good to go  Hope This solves your problem  Cheers

I know this is an old questions but none of the solutions seemed like a good practice hence I am putting how I have solved this issue   Tried solving this issue by using Homebrew but it was also installing node in  usr local directory which would again cause EACCES error   Had to use a version manager like nvm for more informations see the official npm guide      For various operating system    nvm installs node and it s modules in the user s HOME FOLDER thereby solving EACCES issues

npm has an official page about fixing npm permissions when you get the EACCES  Error  Access  error  The page even has a video      You can fix this problem using one of two options          Change the permission to npm s default directory    Change npm s default directory to another directory

Re Explosion Pills  An installation can run arbitrary scripts and running it with sudo can be extremely dangerous    Seems like using sudo is the wrong way of doing it     Change the owner of the files in your  usr local folder to the current user    sudo chown -R  USER  usr local   Then run the install  node install -g less   Check out    npm throws error without sudo https   aralbalkan com scribbles npm-install-g-please-try-running-this-command-again-as-root-administrator  http   foohack com 2010 08 intro-to-npm  what no sudo

Honestly this is bad advice from npm   An installation can run arbitrary scripts and running it with sudo can be extremely dangerous   You could do sudo npm install -g less to install it globally  but instead I would recommend updating your npm settings       npmrc prefix    npm modules   Then you can update your path       bashrc or    zshrc  etc  export PATH  PATH  HOME  npm modules bin   Then you don t require root permissions to perform the installation and you can still use the binary   This would only apply to your user  however   If you want the entire system to be able to use the module you would have to tell everyone to add your path   More complicated and robust solutions would include adding a folder with node modules   binaries that a group could install to and adding that to everyone s path

I was getting this issue for instaling expo cli and I fixed by just following four steps mentioned in the npm documentation here  Problem is some version of npm fail to locate folder for global installations of package  Following these steps we can create or modify the  profile file in Home directory of user and give it a proper PATH there so it works like a charm  Try this it helped me and I spent around an hour for this issue  My node version was 6 0 Steps I follow Back up your computer  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 To test your new configuration  install a package globally without using sudo  npm install -g jshint

This is what I had to do to get started with a Less compiler to avoid issues as mentionned in the OP    Install node js Install NPM with Terminal  sudo npm install npm -g Install a Less compiler with Terminal  sudo npm install -g less  the sudo makes all the difference  If you re using PHPstorm  Go to  Preferences      Plugins  and install NodeJS-plugin  might need to  browse repositories  to find it  and restart PHPstorm  as prompted  After that go to Plugins once again  Install Less compiler  might need to  browse repositories  to find it  and restart PHPstorm  as prompted  Once you have a project set up  go to  Settings   Tools   Filewatchers  and add  Less   The path  of the  Program   should read something like this   usr local bin lessc  Make sure Track only root files is checked in the settings of 6
