Question

同事为我提供了一组用于测试的py文件，这些文件在他的机器上正常运行。但是，当我运行py文件时，我收到以下错误：

Traceback (most recent call last):
  File "D:\workspaces\pyworkspace\Analytics Python\python_server\server1.py", line 84, in <module>
    start_server()
  File "D:\workspaces\pyworkspace\Analytics Python\python_server\server1.py", line 57, in start_server
    socketObj.bind(server_address)
LookupError: unknown encoding: idna

Here，它说要添加import encodings.idna。所以我添加了导入（即使eclipse说“未使用导入”），但仍然得到相同的错误。所以我放了一些断点并开始调试，但调试器没有达到断点。程序termniates没有任何断点给出以下错误：

pydev debugger: starting (pid: 8316)

为什么会这样？（我使用的是python 3.4，eclipse oxygen 4.7和PyDev 6.2.0.201711281614）

Answer 1

显然问题是因为pydev期望matplotlib有一些在你的安装中不可用的模块......所以，导入：

from matplotlib.rcsetup import interactive_bk, non_interactive_bk # @UnresolvedImport

失败了（如果安装了matplotlib，那么在PyDev中会出现这种情况）。

不确定为什么......我需要调查你是否有一个破坏的matplotlib或matplotlib是否实际发生了变化（在这种情况下需要修复pydev调试器）。

您可以在matplotlib版本上添加详细信息吗？

获取未知编码：idna然后无法在eclipse上的python PyDev插件中调试
