python - 即使 pip 已更新，安装软件包时仍出现 Pip 版本错误

Question

当我尝试安装 dateutil 时遇到此错误:

Collecting dateutil

  Could not find a version that satisfies the requirement dateutil (from versions: )
No matching distribution found for dateutil
You are using pip version 10.0.1, however version 19.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

如果我运行pip -V我会得到这个:

pip 19.0.1 from /Users/me/.pyenv/versions/3.7.2/lib/python3.7/site-packages/pip (python 3.7)

我配置过什么东西吗？如何安装 dateutil？

Answer 1

正确的包:

pip install python-dateutil
