Python Eclipse PyDev

Question

我是 Python 的新手。 我在 Windows 7 上下载并安装了 Anaconda 3.5.2，然后安装了 Eclipse Photon。安装了 PyDev 插件。 我能够在 Eclipse 中运行一些简单的测试程序。

突然之间，我没有安装任何东西

Error processing line 1 of C:\Anaconda3\lib\site-packages\matplotlib-2.2.2-py3.6-nspkg.pth:

During handling of the above exception, another exception occurred:

ImportError: cannot import name 'namedtuple'

即使之前运行过“Hello World”

有什么想法可能会导致这种情况吗？
