使用 virtualenvwrapper-win 传递不同 python 版本时出错

Question

我安装了 python 3.4 和 2.7，它们的路径是 C:\python34 和 C:\python27。在尝试使用 python 2.7 创建 virtualenv 时，出现以下错误：

    C:\Development>mkvirtualenv --python=C:\python27 env
    Running virtualenv with interpreter C:\python27
    Traceback (most recent call last):
      File "C:\Python34\lib\runpy.py", line 170, in _run_module_as_main
        "__main__", mod_spec)
      File "C:\Python34\lib\runpy.py", line 85, in _run_code
        exec(code, run_globals)
      File "C:\Python34\Scripts\virtualenv.exe\__main__.py", line 9, in <module>
      File "C:\Python34\lib\site-packages\virtualenv.py", line 784, in main
      popen = subprocess.Popen([interpreter, file] + sys.argv[1:], env=env)
      File "C:\Python34\lib\subprocess.py", line 859, in __init__
         restore_signals, start_new_session)
      File "C:\Python34\lib\subprocess.py", line 1112, in _execute_child
    startupinfo)
    PermissionError: [WinError 5] Access is denied
    The system cannot find the path specified.
    The system cannot find the path specified.
    The system cannot find the path specified.

here 它说：

If you use several versions of python, you can switch between them using a separate project pywin. It’s a lightweight python 2.5-3.3 launcher and switcher I wrote for the Windows command line and MSYS/MINGW32. It’s similar to the py.exe launcher/switcher available in python 3.3, but written with basic Windows batch scripts and a shell script for MSYS/MINGW32 support. I use bash and command line shell tools from msysgit, based on MSYS/MINGW32, to do most of my python development on Windows.

我有 pywin，但不知道如何使用它设置具有不同 python 版本的 virtualenv。

我不确定我的问题是什么，我们将不胜感激。

我应该补充一点，我可以在不使用 virtualenvwrapper-win 的情况下使用 python 2.7 使用 virtualenv。

今天我一直在为这个问题苦苦挣扎。您需要指定 python.exe 文件。

mkvirtualenv -p C:/Python27/python.exe myenv

希望对您有所帮助！
