导入matplotlib在Anaconda python3.6中失败了

Question

我安装了Anaconda以简化许多python模块的管理。

之后我尝试了＃34;导入子流程＆＃34;：

>>> import subprocess
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/sej/.config/anaconda3/lib/python3.6/subprocess.py", line 155, in <module>
    _PopenSelector = selectors.SelectSelector
AttributeError: module 'selectors' has no attribute 'SelectSelector'

如何解决这个问题？

我试图使用matplotlib来解决这个问题。 尝试导入时，会出现此错误：

>>> import matplotlib
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/sej/.config/anaconda3/lib/python3.6/site-packages/matplotlib/__init__.py", line 127, in <module>
    from matplotlib.compat import subprocess
  File "/home/sej/.config/anaconda3/lib/python3.6/site-packages/matplotlib/compat/subprocess.py", line 27, in <module>
    import subprocess
  File "/home/sej/.config/anaconda3/lib/python3.6/subprocess.py", line 155, in <module>
    _PopenSelector = selectors.SelectSelector
AttributeError: module 'selectors' has no attribute 'SelectSelector'
