Answer 1

如果您查看1.2.10-114和1.2.10-139的pefile页面，您会看到一个重要的区别，后者没有带有来源的“文件”部分蛋。这意味着文件是在外部托管的，您需要允许pip从 external和unverified来源安装：

pip install pefile --upgrade --allow-external=pefile --allow-unverified=pefile

演示：

$ pip show pefile
---
Name: pefile
Version: 1.2.10-114

$ pip install pefile --upgrade --allow-external=pefile --allow-unverified=pefile
pefile an externally hosted file and may be unreliable
pefile is potentially insecure and unverifiable.
