python - 如何从外部托管源 pip 安装 pyx 包？

Question

pip 知道 pyx 包:

$ pip search pyx
PyX - Python package for the generation of PostScript and PDF files

尝试安装它时出现错误:

$ pip install pyx
Collecting pyx
  Could not find any downloads that satisfy the requirement pyx
  Some externally hosted files were ignored as access to them may be unreliable (use --allow-external pyx to allow).
  No distributions at all found for pyx

我按照错误信息使用了--allow-external pyx，但是得到了一个不同的错误:

$ pip install --allow-external pyx
You must give at least one requirement to install (see "pip help install")

如何使用pip安装pyx包？

Answer 1

您需要告诉 pip 允许外部 pyx 包和实际安装它。

pip install --allow-external pyx pyx

按照这个顺序写，看起来有 pip 多余，但是要安装的包名和--allow-external选项是分开的。
