Question

我有一些运行得很好的代码，在一天中，我打破了一些东西，现在我无法安装任何python模块。具体来说，我需要numpy，matplotlib和枕头。我无法安装任何一个。

但奇怪的是，它们似乎都安装得很好：

$ sudo pip install numpy

或者当我尝试时：

它为我尝试安装的任何模块执行此操作。任何帮助将不胜感激。

这是默认python和默认pip不匹配的结果。要确保将软件包安装到正确的位置，请使用：

python -m pip install $PACKAGE

这会导致分配给所需pip的{{1}}而不是您路径中找到的第一个{。}}。

Python模块没有安装
