Error importing virtualenvwrapper to the Powershel

问题:

I have python 2.7 installed perfectly, and also pip, and I have been running the PowerShell as admin.

I did:

pip install virtualenv

and

pip install virtualenvwrapper-powershell

and they both were succesfull.

I also did this:

mkdir '~.virtualenvs'

However, whenever I try to:

Import-Module virtualenvwrapper

it always gets me this error: Import-Module: The specific module 'virtualenvwrapper' was not loaded because no valid module file was found in any module directory.

I did pip install virtualenvwrapper-powershell again just to make sure, and I got this: Requirement already satisfied (use --upgrade to upgrade): virtualenvwrapper-powershell in c:\python27\lib\site-packages

What could be wrong ?

I met the same problem when I tried to do the exact same thing as what you did. Finally I figured it out. I found that the virtualenvwrapper I installed is somehow not in the current folder (C:). Instead, it is hidden in the folder:

C:\Python27\Lib\site-packages\Users\*myusername*\Documents\WindowsPowerShell\Modules\VirtualEnvWrapper

I recommend you go to your Python folder and try to search something like

"\Lib\site-packages\Users\*myusername*\Documents\WindowsPowerShell\Modules\"

and if you can find the module VirtualEnvWrapper there, then when you type the command, you just need to include the complete path.

I hope it will help.

You must be following the setup instructions for http://newcoder.io/begin/setup-your-machine/#windows. Me too. Here is how I fixed it:

1. From Powershell, type "Get-ChildItem Env:PSModulePath" The value of this variable tells you the folder that Powershell looks when importing modules.
2. pip installed my module to "C:\Python27\Lib\site-packages\Users\\Documents\WindowsPowerShell\Modules\virtualenvwrapper"
3. Copy that folder to the folder from step #1
4. Restart Powershell

This helped me out so much

After going to pc -> C: -> Python27 -> Lib -> site-packages -> users -> * your user * -> WindowsPowerShell -> Modules -> Copy the VirtualEnvWrapper

In a self made directory in Documents call it WindowsPowerShell and then make another inside it called Modules Copy the VirtualEnvWrapper folder within this.

then drop a set-executionpolicy unrestricted in CMD as ADMINISTRATOR !!!

followed by a Import-Module virtualenvwrapper

and you should be 100%

I had the same issue today on a fresh win 10 system. For some reason the VirtualEnvWrapper seems to create a User folder in the site-packages folder inside your Python installation, where it can't be found. Just moving the "Modules" with all its content did the trick. -> (in my case from:) C:\Program Files (x86)\Python27\Lib\site-packages\Users\*USER*\Documents\WindowsPowerShell\**Modules**\VirtualEnvWrapper

-> to C:\Users\*USER*\Documents\WindowsPowerShell\**Modules**\VirtualEnvWrapper ..did the trick... where your powershell profile can find it ;)
