Question

Pip知道pyx包：

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

尝试安装它会出错：

$ 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

我按照错误消息使用了--allow-external pyx，但出现了不同的错误：

$ 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

你需要告诉pip允许外部pyx包和实际安装它。

pip install --allow-external pyx pyx

按顺序编写，似乎是多余的，但要安装的软件包名称与--allow-external选项是分开的。

Answer 2

嗯，我有同样的问题，但我使用给定的命令解决了问题。

下面提到的命令是python2

sudo pip install pyx == 0.12.1

如何从外部托管的源代码安装pyx包？
