Question

我开始一个新的python项目，当我尝试安装虚拟环境时，wrapt一直失败。我已经阅读并尝试了所有可以在这里和其他论坛上找到的所有解决方案，但都没有成功。

您能想到问题再解决吗？这是很奇怪的，因为相同的项目和代码可以在其他类似的Windows机器上运行...

谢谢！

Answer 1

在运行前固定设置了以下变量：pipenv --three install

设置WRAPT_INSTALL_EXTENSIONS = false

Answer 2

我得到了相同的堆栈跟踪，我的问题是我的计算机上没有安装最新的Microsoft Visual C ++ Redistributable。有点愚蠢，但是安装脚本只是查找dll，如果不存在该错误就会中断此错误，而不是先检查它并显示有意义的错误消息...

堆栈跟踪的重要部分：

[pipenv.exceptions.InstallError]:     File "c:\users\admin\.virtualenvs\git_project-ubvgpj5x\lib\site-packages\setuptools\msvc.py", line 171, in msvc14_get_vc_env
[pipenv.exceptions.InstallError]:       return EnvironmentInfo(plat_spec, vc_min_ver=14.0).return_env()
[pipenv.exceptions.InstallError]:     File "c:\users\admin\.virtualenvs\git_project-ubvgpj5x\lib\site-packages\setuptools\msvc.py", line 1620, in return_env
[pipenv.exceptions.InstallError]:       if self.vs_ver >= 14 and isfile(self.VCRuntimeRedist):
[pipenv.exceptions.InstallError]:     File "c:\users\admin\.virtualenvs\git_project-ubvgpj5x\lib\genericpath.py", line 30, in isfile
[pipenv.exceptions.InstallError]:       st = os.stat(path)
[pipenv.exceptions.InstallError]:   TypeError: stat: path should be string, bytes, os.PathLike or integer, not NoneType
[pipenv.exceptions.InstallError]:   ----------------------------------------

如果未安装C ++ Redistributable，则

self.VCRuntimeRedist将返回None，当用isfile调用None时，将导致此错误。

Windows上的Pipenv失败，并出现安装wrapt的错误（Python 3.6.8）
