Question

这已经由我自己解决了，但我将这个问题转给其他人。我认为这种问题尽可能地好。而且似乎没有SOF。

我更新了spyder和PyQt5。

conda update spyder
Collecting package metadata: done
Solving environment: done

## Package Plan ##

  environment location: C:\Anaconda3

  added / updated specs:
    - spyder


The following packages will be downloaded:

    package                    |            build
    ---------------------------|-----------------
    anaconda-custom            |   py36h363777c_0           9 KB
    spyder-3.3.4               |           py36_0         2.6 MB
    spyder-kernels-0.4.4       |           py36_0          68 KB
    ------------------------------------------------------------
                                           Total:         2.7 MB

The following packages will be UPDATED:

  spyder                                       3.3.3-py36_0 --> 3.3.4-py36_0
  spyder-kernels                               0.4.2-py36_0 --> 0.4.4-py36_0

The following packages will be DOWNGRADED:

  anaconda                                   2019.03-py36_0 --> custom-py36h363777c_0

当我尝试启动spyder时。从快捷方式图标，没有应用程序发生。所以我写了这个cmd。

 C:\Users\****>spyder

但是我有这个错误

Traceback (most recent call last):
  File "C:\Anaconda3\Scripts\spyder-script.py", line 10, in <module>
    sys.exit(main())
  File "C:\Anaconda3\lib\site-packages\spyder\app\start.py", line 186, in main
    from spyder.app import mainwindow
  File "C:\Anaconda3\lib\site-packages\spyder\app\mainwindow.py", line 90, in <module>
    from qtpy import QtWebEngineWidgets  # analysis:ignore
  File "C:\Anaconda3\lib\site-packages\qtpy\QtWebEngineWidgets.py", line 22, in <module>
    from PyQt5.QtWebEngineWidgets import QWebEnginePage
ValueError: PyCapsule_GetPointer called with incorrect name

所以，我搜索了this page。

我遵循了解决方案。但这不是同一个问题。

下一个问题发生。

python: can't open file 'configure.py': [Errno 2] No such file or directory

我该如何解决？

Python 3.6.8 |Anaconda custom (64-bit)| (default, Feb 21 2019, 18:30:04) [MSC v.1916 64 bit (AMD64)]

解决方案是降级PyQt5。

pip install PyQt5==5.10.1
Collecting PyQt5==5.10.1

Requirement already satisfied: sip<4.20,>=4.19.4 in c:\anaconda3\lib\site-packages (from PyQt5==5.10.1) (4.19.8)
spyder 3.3.4 requires pyqtwebengine<5.13, which is not installed.
Installing collected packages: PyQt5
  Found existing installation: PyQt5 5.12.1
    Uninstalling PyQt5-5.12.1:
      Successfully uninstalled PyQt5-5.12.1
Successfully installed PyQt5-5.10.1

发生此问题是因为我安装的PyQt5的版本超出了spyder的版本。

用<from pyqt5.qtwebenginewidgets =“” import =“” qwebenginepage =“”>用错误的名称调用ValueError：PyCapsule_GetPointer
