poewrshellを使って、Data Visualizationを学びはじめた者です。
Pythonのversionは2.7
windowsは8.1を使用しています。

私の、システム環境変数パスは、下記の通りです。

c:\python27\;c:\python27\scripts;c:\python27\tools\scripts;C:\Program Files (x86)\Common Files\Apple\Apple Application Support;C:\Program Files (x86)\Intel\iCLS Client\;C:\Program Files\Intel\iCLS Client\;C:\windows\system32;C:\windows;C:\windows\System32\Wbem;C:\windows\System32\WindowsPowerShell\v1.0\;C:\Program Files\Intel\Intel(R) Management Engine Components\DAL;C:\Program Files\Intel\Intel(R) Management Engine Components\IPT;C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\DAL;C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\IPT;C:\Program Files (x86)\Windows Live\Shared;C:\Program Files\Intel\WiFi\bin\;C:\Program Files\Common Files\Intel\WirelessCommon\;C:\Program Files (x86)\Common Files\Roxio Shared\DLLShared\;C:\Program Files (x86)\Common Files\Roxio Shared\OEM\12.0\DLLShared\;C:\Program Files (x86)\Roxio 2010\OEM\AudioCore\;C:\Program Files (x86)\Brackets\command;C:\Program Files (x86)\QuickTime\QTSystem\;C:\Program Files (x86)\Skype\Phone\;C:\Program Files\Git\bin;C:\Program Files (x86)\Git\cmd

現在、基本的に(http://newcoder.io/begin/setup-your-machine/#windows)のガイダンスに沿って、コンピューター環境を整えている状態です。
powershell, python, git, pip, virtualenv, virtualenvwrapper-powershellのインストールは(助けてもらいながら)順調に進んだのですが、
type:Import-Module virtualenvwrapper という所でスタックしてしまいました。。(virtualenvwrapper-powershellのインストールは完了しています。。)

私が、Import-Module virtualenvwrapperと入力すると、以下のエラーメッセージが得られます。

PS C:\python27> Import-Module virtualenvwrapper
Import-Module : The specified module 'virtualenvwrapper' was not loaded because no valid module file was found in any
module directory.

    + CategoryInfo          : ResourceUnavailable: (virtualenvwrapper:String) [Import-Module], FileNotFoundException
    + FullyQualifiedErrorId : Modules_ModuleNotFound,Microsoft.PowerShell.Commands.ImportModuleCommand

また、モジュールを、そのモジュールと同じ名前のフォルダに保存するか、.psm1をコマンドに使うと上手くいくかもしれないよ。とのご指摘を頂き、((https://stackoverflow.com/questions/31096527/import-module-virtualenvwrapper/31097136#31097136))

C:\Python27\virtualenvwrapper

 にvirtualenvwrapper.psm1を配置し、
Import-Module virtualenvwrapperを実行してみましたが、エラーメッセージは上記と同じでした。。

また、Import-Module virtualenvwrapper.psm1も実行してみましたが、以下のエラーメッセージが得られました。。。

また、 Import-Module C:\Python27\virtualenvwrapper\virtualenvwrapper.psm1 も実行してみましたが、以下のエラーメッセージが得られました。。。

また、このページを参考に(https://stackoverflow.com/questions/31035903/installing-virtualenvwrapper-powershell-in-windows-8-1-import-module-failing)、
WindowsPowerShell\Modules というフォルダーをドキュメントに作成し、(the virtualenvwrapper-powershell bitbucket )からとってきた、VirtualEnvWrapper ディレクトリを
Modulesフォルダに設置し、Set-ExecutionPolicy Unrestricted を実行してからImport-Module virtualenvwrapperを実行したのですが、やはりエラーとなりました。。

エラーメッセージは以下の通りです。

PS C:\python27> Set-ExecutionPolicy Unrestricted

you to the security risks described in the about_Execution_Policies help topic at

長々と申し訳ございませんでした。
どなたか、何かアイデアのございます方、お力を貸して頂けますと助かります。。

遂に成功したかのように見えます。以下のメッセージの様に、今回のエラーは、『TabExpansion』によるものだけで、これは無視してよいエラーみたいです!
ということは、今回の”Import-Module virtualenvwrapper”の実行は、成功かと思います。
しかし、メッセージ中に、何も『成功』形跡がありません。。
これは本当に成功したのでしょうか。。
