由于环境错误而无法安装软件包：[Errno 2] 没有这样的文件或目录

Question

这就是我用来安装软件包的方法，唯一有效的是 requests

pip._internal.main(['install', 'requests'])
pip._internal.main(['install', 'lxml'])
pip._internal.main(['install', 'cssselect'])
pip._internal.main(['install', 'selenium'])

这是我在控制台中收到的错误消息

我对Python相当陌生，只是一般性地编码，我真的不知道这些错误意味着什么，而且我在谷歌上找不到我理解的任何内容，所以任何帮助都将不胜感激。

这是在 Visual Studio 代码和 Python 3.7.1 中

Answer 1

我知道这已经晚了，但我想这会帮助其他面临类似问题的人。

在路径中：

C:\\Users\\user\\AppData\\Local\\Temp\\pip-req-tracker-047sxufq\\b3025a26893a7657747ef91c7e8a7d138021b8a645639c56cd0046c5

"AppData"

文件夹及其内容可能被 Windows 标记为

"Hidden"

和/或

"Read only"

，取消勾选这些并将它们指定为普通文件夹可能会有所帮助。

这是唯一帮助我的解决方案。请尝试一下并发表评论。

Answer 2

他的回答对我有用https://stackoverflow.com/users/15757753/abhishek-v

考虑到我的 AppData 为 90 GB，大约需要 50 分钟才能取消隐藏所有内容，但效果非常好。
