pip安装错误：ModuleNotFoundError没有名为“ setuptools”的模块

Question

When I run pip install virtualenvwrapper-win in a PowerShell console I get the error:

PS C:\\Windows\\system32> pip install virtualenvwrapper-win Collecting virtualenvwrapper-win Using cached virtualenvwrapper-win-1.2.1.zip Complete output from command python setup.py egg_info: Traceback (most recent call last): File "", line 1, in ModuleNotFoundError: No module named 'setuptools'

Command "python setup.py egg_info" failed with error code 1 in

I've tried doing pip install setuptools and also tried uninstalling and reinstalling and update but the error persists.

pip and python executables have been added to environment variables.

Try installing the virtualenvwrapper-win module manually by downloading the ZIP archive from here: https://pypi.python.org/pypi/virtualenvwrapper-win

• In your PowerShell console, go to the directory the archive downloaded to (mine goes to C:\\Users\\user\\Downloads\\ ) and run this to extract the archive: Expand-Archive .\\virtualenvwrapper-win-1.2.1.zip

• Still in PowerShell and in the same directory as above, run: cd .\\virtualenvwrapper-win-1.2.1\\virtualenvwrapper-win-1.2.1\\

• Next, run: python setup.py install

If all went well, you should see something like this:

    PS C:\Users\user\Downloads\virtualenvwrapper-win-1.2.1\virtualenvwrapper-win-1.2.1> python .\setup.py install

Answer 2

virtualenvwrapper-win is only intended for the DOS cmd.exe. From the README:

These scripts should work on any version of Windows (Windows XP, Windows Vista, Windows 7/8/10).

However, they only work in the regular command prompt . They will not work in Powershell. There are other virtualenvwrapper projects out there for Powershell.
