这是 SO 上一个真正受欢迎的问题,但我看过的许多答案中没有一个能清楚地解释这个错误的真正含义以及它发生的原因。一个混乱的来源是,当(例如)你这样做时pip install pycparser,你首先得到错误:Failed building wheel for pycparser然后是消息包是:Successfully installed pycparser-2.19.# pip3 install pycparserCollecting pycparser Using cached https://files.pythonhosted.org/packages/68/9e/49196946aee219aead1290e00d1e7fdeab8567783e83e1b9ab5585e6206a/pycparser-2.19.tar.gzBuilding wheels for collected packages: pycparser Running setup.py bdist_wheel for pycparser ... error Complete output from command /usr/bin/python3 -u -c "import setuptools, tokenize;__file__='/tmp/pip-install-g_v28hpp/pycparser/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" bdist_wheel -d /tmp/pip-wheel-__w_f6p0 --python-tag cp36: Traceback (most recent call last): File "<string>", line 1, in <module> ...

因为,除了我自己,似乎没有人提到这一点。我自己解决上述问题是最常见的,以确保禁用缓存使用副本:pip install <package> --no-cache-dir
