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

我遵循错误消息并使用--allow-external pyx，但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软件包？

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

按照这个顺序编写，它看起来是多余的，但要安装的程序包名称与--allow-external选项是分开的。

Answer 2

好吧，我也遇到了同样的问题，但我使用给定的命令解决了这个问题。

下面提到的命令适用于python2

sudo pip安装pyx==0.12.1
