Error after upgrade ... but upgrade seems successful

[warrenhales]

@felixrieseberg I just updated to version 0.2.3 of npm-windows-upgrade because I was having the same issue described in issue #10

I then ran it (on Windows 8.1 pro) and got this error message:

PS C:\windows\system32> npm-windows-upgrade
npm-windows-upgrade 0.2.3
? This tool will upgrade npm. Do you want to continue? Yes
? Which version do you want to install? 2.12.1
Upgrading.. \

You wanted to install npm 2.12.1, but the installed version is2.11.2.
Please consider reporting your trouble to http://aka.ms/npm-issues.
Here is the output from the upgrader script:
[ '\r\n',
  '\r\n',
  '    Directory: C:\\Users\\Warren\\AppData\\Local\\Temp\r\n',
  '\r\n',
  '\r\n',
  'Mode                LastWriteTime     Length Name
  \r\n',
  '----                -------------     ------ ----
  \r\n',
  'd----          7/7/2015   1:58 PM            npm_upgrade
  \r\n',
  'npm@2.12.1 node_modules\\npm\n',
  'All done!\r\n',
  '\r\n',
  '\r\n' ] []

But despite the error message, it looks like the upgrade happened:

PS C:\windows\system32> npm list -g --depth=0
C:\Users\Warren\AppData\Roaming\npm
├── bower@1.4.1
├── gulp@3.8.11
├── npm@2.12.1
├── npm-check@3.2.10
└── npm-windows-upgrade@0.2.3

I am new to node and npm so could be just something weird I did to my environment while learning and experimenting but thought I would report it.

Actually ... now I am not sure if the update actually worked. Despite what the list command is reporting (see above) doing npm -v returns 2.11.2

Closed powershell and re-opened and ran npm-windows-upgrade again and received a different error:

Just noticed something that may be relevant to this issue:

My node installation is in C:\nodejs

But reading the manual solution it sounds like the assumption is node is installed in

C:\Program Files (x86)\nodejs

Actually, I have hopes that the just released version 0.3.2 will fix your issue. Do me a favour and run npm install -g npm-windows-upgrade and npm-windows-upgrade again.
