【问题描述】：
我正在尝试使用 Python 3.2.3 在 virtualenv 中安装 matplotlib。我已经尝试从可下载的存档和 pip 安装它。在这两种情况下，安装过程都会卡住，直到我用 ^C 中断它。为什么会这样？
这是安装过程的输出：

【问题讨论】：
-
setupext.CheckFailed: PySide not found?也许你应该安装它。我不知道这是否真的是问题所在，但尝试没有坏处。 -
@Veedrac 不能完全解释冻结，但我会尝试。
-
这是一个已知问题github.com/matplotlib/matplotlib/issues/3444 问题在于 mpl 不再正式支持的 python 3.2。
