go to http   nodejs org   and hit the button that says  Download For       This ll download the  msi  or  pkg for mac  which will do all the installation and paths for you  unlike the selected answer

New installers   msi downloaded from https   nodejs org  have  Add to PATH  option  By default it is selected  Make sure that you leave it checked

The reason why you have to modify the AppData could be    Node js couldn t handle path longer then 256 characters  windows tend to have very long PATH   If you are login from a corporate environment  your AppData might be on the server - that won t work  The npm directory must be in your local drive    Even after doing that  the latest LTE  4 4 4  still have problem with Windows 10  it worked for a little while then whenever I try to     npm install  some package  --global    Node throw the  FATAL ERROR CALL AND RETRY LAST Allocation failed - process out of memory  error  Still try to find a solution to that problem    The only thing I find works is to run Vagrant or Virtual box  then run the Linux command line  must matching the path  which is quite a messy solution

Edit  It seems like new installers do not have this problem anymore  see this answer by Parag Meshram as my answer is likely obsolete now   Original answer   Follow these steps  closely    http   nodejs org download  download the 64 bits version  32 is for hipsters Install it anywhere you want  by default   C  Program Files nodejs Control Panel -  System -  Advanced system settings -  Environment Variables Select PATH and choose to edit it    If the PATH variable is empty  change it to this  C  Users  YOUR USERNAME HERE  AppData Roaming npm C  Program Files nodejs  If the PATH variable already contains C  Users  YOUR USERNAME HERE  AppData Roaming npm  append the following right after   C  Program Files nodejs  If the PATH variable contains information  but nothing regarding npm  append this to the end of the PATH   C  Users  YOUR USERNAME HERE  AppData Roaming npm C  Program Files nodejs  Now that the PATH variable is set correctly  you will still encounter errors  Manually go into the AppData directory and you will find that there is no npm directory inside Roaming  Manually create this directory   Re-start the command prompt and npm will now work

I had the same problem  what helped we was turning of my anti virus protection for like 10 minutes while node installed and it worked like a charm

In addition to the answer from  StephanBijzitter I would use the following PATH variables instead    appdata  npm  ProgramFiles  nodejs   So your new PATH would look like    existing stuff   appdata  npm  ProgramFiles  nodejs   This has the advantage of neiter being user dependent nor 32 64bit dependent

Everything should be installed in  appdata   C  Users  AppData Roaming   not  program files    Here s why     The default MSI installer puts Node and the NPM that comes with it in  program files  and adds this to the system path  but it sets the user path for NPM to  appdata   c  users username  appdata roaming  since the user doesn t have sufficient priveleges to write to  program files    This creates a mess as all modules go into  appdata   and when you upgrade NPM itself - which NPM themselves recommend you do right away - you end up with two copies  the original still in  program files  since NPM can t erase that  and the new one inn  appdata    Even worse  if you mistakenly perform NPM operations as admin  much easier on Windows then on  nix  then it will operate on the  program files  copy of NPM node modules   Potentially a real mess   So  when you run the installer simply point it to  appdata  and avoid all this   And note that this isn t anything wierd - it   s what would happen if you ran the installer with just user priveleges

You should run the installer as administrator     Run the command prompt as administrator cd directory where msi file is present launch msi file by typing the name in the command prompt You should be happy to see all node commands work from new command prompt shell
