PermissionError: [WinError 32] 该进程无法访问该文件，因为该文件正在被另一个进程使用：安装 python-certifi-win32 后

Question

我安装了 python-certifi-win32 包，之后，当我导入任何内容或 pip install 任何内容时，出现以下错误，失败并出现 PermissionError 的最终错误。

我尝试重新启动盒子。它不起作用。我无法卸载该软件包，因为 pip 也出错了。

我无法弄清楚发生此错误的确切原因。它似乎不是特定于代码的，似乎与我安装的库有关

Answer 1

我今天遇到了同样的问题。我通过删除安装 python-certifi-win32 时创建的两个 *.pth 文件来纠正它。这可以防止 python-certifi-win32 在 python 运行时加载。

下面列出了这些文件，它们位于此处：

C:\Users\<username>\AppData\Local\Programs\Python\Python310\Lib\site-packages

文件：

python-certifi-win32-init.pth
distutils-precedence.pth

删除这些文件允许我安装/卸载其他模块。

Answer 2

的作者 Andrew Leechpython-certifi-win32建议继续他的另一个项目pip-system-certs（PyPI 链接）。直接替换为我解决了所有问题python-certifi-win32。pip-system-certs

虽然此答案中提供的解决方案也阻止了我在问题中提到的错误消息，但它带来了副作用，即我的 Python 脚本不再使用 Windows 证书存储中的证书，再次导致 SSL 证书错误 - 渲染使用库没用。
