Anaconda's own Spyder editor starts with an error

On trial Anaconda When you bring your own science editor , There are several questions about PyQt Framework issues （ May be Spyder Is based on Pyqt5 Developed , I didn't know the details carefully ）.

Let's look at the problem first ：

No module named 'PyQt5.QtWebKitWidgets' 'PyQt5.QtWebEngineWidgets'

The first is that we can't find PyQt5 A submodule , I checked , Due to the version update , stay PyQt 5.6(+) In the version , newly added QtWebEngineWidgets Instead of QtWebKitWidgets.

According to the error path prompted , find QtWebEngineWidgets.py The number of this document 27 That's ok , Here's the picture ：

Here is the 27、28 Two lines of comment （ Delete ） fall , Change to as 30、31 Those two lines , But I don't know if this is right PyQt5 Other aspects of the framework are used to cause failures , It is recommended to note first , To be observed .

Start again after the change Spyder, You will find that an error is reported again ：

from PyQt5.QtWebEngineWidgets import *：ImportError: DLL load failed / The specified module was not found , Only the following installation is required ：

 pip install PyQtWebEngine

There may be   Following mistakes （PyQt5 The version is too high to be compatible Spyder）, However, the module was successfully installed in the end , and Spyder It can be started normally , No problems have been found during use .
