每次我运行“pip”安装任何包时，它都会显示一些警告

Question

I get these warning 2 times. After the pip is run and second when pip has finished executing

Here is an example of what is happening.

以下为文本：

pip install pygame

当pip删除包时，它首先用-重命名第一个字母。例如，opencv-python变为-pencv-python。如果unistall失败，重命名的目录将保留在那里，但它无效

您可能必须手动删除这些文件夹，以消除警告
