Question

我正在尝试运行Spyder IDE，但它失败了，因为它导入了错误的文件。我得到ImportError尝试从命令行运行它：

$ /opt/anaconda3/bin/spyder 
Traceback (most recent call last):
  File "/opt/anaconda3/bin/spyder", line 6, in <module>
    sys.exit(spyder.app.start.main())
  File "/opt/anaconda3/lib/python3.5/site-packages/spyder/app/start.py", 
line 103, in main
    from spyder.app import mainwindow
  File "/opt/anaconda3/lib/python3.5/site-packages/spyder/app/mainwindow.py",
 line 78, in <module>
    from qtpy.compat import from_qvariant
  File "/opt/anaconda3/lib/python3.5/site-packages/qtpy/compat.py", 
line 15, in <module>
    from qtpy.QtWidgets import QFileDialog
  File "/opt/anaconda3/lib/python3.5/site-packages/qtpy/QtWidgets.py", 
line 27, in <module>
    from PyQt5.QtWidgets import *
ImportError: /opt/anaconda3/lib/python3.5/site-packages/PyQt5/Qt/lib/libQt5Gui.so.5:
symbol _Z10qAllocMoreii, version Qt_5 not defined in file libQt5Core.so.5 with 
link time reference

然而，当我从/opt/anaconda3/bin/python命令from PyQt5.QtWidgets import *的python解释器运行时，它运行正常。好的，我觉得这是一个sys.path问题。所以我修改/opt/anaconda3/lib/python3.5/site-packages/qtpy/QtWidgets.py以打印出系统路径和系统可执行文件。相关的代码段是：

print(sys.path)
print(sys.executable)
from PyQt5.QtWidgets import *

打印结果：

['/opt/anaconda3/bin', '/opt/anaconda3/lib/python35.zip', 
'/opt/anaconda3/lib/python3.5', 
'/opt/anaconda3/lib/python3.5/plat-linux', 
'/opt/anaconda3/lib/python3.5/lib-dynload', 
'/opt/anaconda3/lib/python3.5/site-packages', 
'/opt/anaconda3/lib/python3.5/site-packages/Sphinx-1.4.6-py3.5.egg', 
'/opt/anaconda3/lib/python3.5/site-packages/setuptools-27.2.0-py3.5.egg']

/opt/anaconda3/bin/python

解释器对相同两个命令的结果是：

['', '/opt/anaconda3/lib/python35.zip', 
'/opt/anaconda3/lib/python3.5', 
'/opt/anaconda3/lib/python3.5/plat-linux', 
'/opt/anaconda3/lib/python3.5/lib-dynload', 
'/opt/anaconda3/lib/python3.5/site-packages', 
'/opt/anaconda3/lib/python3.5/site-packages/Sphinx-1.4.6-py3.5.egg', 
'/opt/anaconda3/lib/python3.5/site-packages/setuptools-27.2.0-py3.5.egg']

/opt/anaconda3/bin/python

所以除了第一个目录之外，路径完全相同，但这是无关紧要的，因为解释器在正确的目录中找到了相应的库：

$ /opt/anaconda3/bin/python
>>> import PyQt5.QtWidgets
>>> print(PyQt5.QtWidgets)
<module 'PyQt5.QtWidgets' from 
'/opt/anaconda3/lib/python3.5/site-packages/PyQt5/QtWidgets.so'>

总而言之，即使我使用相同的系统路径相同的解释器，我在两个不同的位置使用相同的导入命令找到两个不同的文件。怎么可能？如何防止它做任何事情？

无意中使用相同的python解释器和系统路径找到两个不同的文件
