我试图导入pyplot但我的
python代码将无法运行并卡在以下位置：

从matplotlib导入pyplot作为plt

我已经尝试使用pip卸载matplotlib,以便我可以重新安装该软件包,但这也会引发一个冗长的错误列表.我在Mac OSX 10.11上运行它.

最佳答案 更好地使用Conda.

我也遇到过这个问题[在windows中].我完全卸载并重新安装了python.然后,它是完美的.我想,这是因为文件损坏了.不过,我搬到了conda环境.它更光滑舒适.

>从Scipy页面下载Anaconda
>打开Conda命令提示符
>使用代码：-conda install pymc pymc
>此代码安装Conda环境,Scipy,Pymc,Numpy,matplotlib和设置工具
>如果只想要matplotlib,可以使用pip install matplotlib.

它对我有用.

如果您想重新使用现有框架,请更好地卸载python安装程序并重新安装.然后尝试pip安装.它运作顺利.

希望这可以帮助.
