I have downloaded and installed the new version of nodejs (4.1.2) using the .msi installer. After that I ran node -v, but it still shows the older version (0.12.2). I tried restarting Windows and even uninstalled nodejs and reinstalled it, but still it shows the same. Why is that happening and how can I resolve it?

Run a search for multiple copies of node.exe in the usual install paths:

  • Program Files

      Get-ChildItem -File -path $env:PROGRAMFILES -include node.exe -recurse -force

  • Program Files(x86)

      Get-ChildItem -File -path $env:PROGRAMFILESX86 -include node.exe -recurse -force

  • Common Files

      Get-ChildItem -File -path $env:COMMONPROGRAMFILES -include node.exe -recurse -force

  • Roaming

      Get-ChildItem -File -path $env:APPDATA -include node.exe -recurse -force

Upgrading npm has its own issues:

Chances are that you attempted to upgrade npm before, it somehow failed, and you then went looking for this tool. If the tool fails to upgrade, it may be troubled by partial changes done during npm install npm or npm upgrade npm. In that case, you will have to completely uninstall Node:

Uninstall Node.js (select Uninstall, not the Repair option).

Go into %programfiles%\nodejs and delete the entire folder.

Delete %appdata%\npm and %appdata%\npm-cache.

Edit your PATH and remove everything that references npm (to do so, hit "Start" and search for "Environment Variables").

Reinstall Node, then install this tool - and only use this tool to upgrade npm, do not attempt to run npm install npm.

  • Well, I solved this problem long ago. The reason of this problem was indeed multiple existence of node.js installation. – Nafis Abdullah Khan Sep 09 '16 at 19:35
  • I had a similar issue, had two instances of node installed, so I removed one through Control Panel, other one, older version, I just deleted the folder. After this clean installation of new version works with no issues. Thx Paul. – goran Oct 17 '16 at 07:51
