pip install中“X的构建失败”是什么意思?

all

这是 SO 上一个非常受欢迎的问题,但我看过的许多答案都没有清楚地解释这个错误的真正含义以及它发生的原因。

混淆的一个来源是,当(例如)你这样做时pip install pycparser,你首先会得到错误:

Failed building wheel for pycparser

然后是包裹的消息:

Successfully installed pycparser-2.19.


# pip3 install pycparser

因为,除了我自己,似乎没有人提到这一点。我自己对上述问题的解决方案通常是确保使用以下方法禁用 缓存 副本: pip install<package> --no-cache-dir.
