当一切都失败，时间紧迫，核弹当前安装的软件包。 – smci 2014-12-05 00:50:08

如果你看一下pefile页1.2.10-114和1.2.10-139 - 你会看到一个重要的区别，后者不具备一个“文件”部分的来源和蛋。这意味着，该文件被外部托管，你需要允许pip从一个external和unverified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.
