Windows 10上的Pip Install Spyder（无法启动）

jippyjoe4

我似乎无法在Windows 10版本1607内部版本14393上使用Pip和Python 3.7.0卸载Spyder。完成安装后，在PowerShell中键入“ spyder3”会创建一个简短的纺车，然后什么也不做。

我在相同版本的Windows虚拟机中验证了此问题，安装了全新的Python 3.7.0，安装了spyder的pip，然后仍然遇到相同的问题。

这是安装时得到的输出（也许有帮助，我不知道）

双击位于的“ spyder.exe”文件时，我遇到相同的问题C:\Program Files\Python\Python37\Scripts\spyder3.exe。另外，我尝试了以下操作（在PowerShell中）：

python
from spyder.app import start
start.main()

但是后来我得到了这个错误：

Traceback (most recent call last):
  File "C:\Program Files\Python\Python37\lib\site-packages\qtpy\QtWebEngineWidgets.py", line 22, in <module>
    from PyQt5.QtWebEngineWidgets import QWebEnginePage
ModuleNotFoundError: No module named 'PyQt5.QtWebEngineWidgets'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Program Files\Python\Python37\lib\site-packages\spyder\app\start.py", line 178, in main

    from PyQt5.QtWebKitWidgets import QWebPage as QWebEnginePage
ModuleNotFoundError: No module named 'PyQt5.QtWebKitWidgets'

所以我尝试了一下pip install PyQt5，但是它告诉我这个要求已经满足了，此后再次尝试使用spyder仍然无济于事。

我不确定如何解决此问题。看来我什么也做不了，间谍工作了。你知道如何解决这个问题吗？

现在PyQtWebEngine是在其自己的包，分开PyQt5。
