Spyder无法在cmd中启动

Question

当我尝试在cmd中运行spyder (任何版本的spyder)时，我得到以下错误。

Traceback (most recent call last):
  File "C:\Users\bjwil\Anaconda3\Scripts\spyder-script.py", line 10, in <module>
    sys.exit(main())
  File "C:\Users\bjwil\Anaconda3\Lib\site-packages\spyder\app\start.py", line 186, in main
    from spyder.app import mainwindow
  File "C:\Users\bjwil\Anaconda3\Lib\site-packages\spyder\app\mainwindow.py", line 87, in <module>
    from qtpy import QtSvg  # analysis:ignore
  File "C:\Users\bjwil\Anaconda3\Lib\site-packages\qtpy\QtSvg.py", line 14, in <module>
    from PyQt5.QtSvg import *
ImportError: DLL load failed: The specified procedure could not be found.

在Windows的MinGW Git中运行spyder时，我没有得到这个错误。我已经找了几个小时，但似乎找不到原因的答案。我在Anaconda3文件夹中有来自Anaconda3的python3.dll和python36.dll扩展。我也不能卸载PyQt5 (获取PackagesNotFoundError: The following packages are missing from the target environment: - pyqt5)并使用conda install -c dsdale24 pyqt5或conda install --channel https://conda.anaconda.org/bpentz pyqt5重新安装。我得到了：

Collecting package metadata: done
Solving environment: failed

UnsatisfiableError: The following specifications were found to be in conflict:
  - conda[version='>=4.6.7']
  - pyqt5
Use "conda search <package> --info" to see the dependencies for each package. 

Answer 1

conda update --all为我修复了同样的问题。

Answer 2

这个问题可能有不同的原因。有时是因为您忘记在anaconda环境中安装spyder。

您可以在anaconda提示符下运行以下命令来安装Spyder

conda install spyder

此外，您还可以转到anaconda导航器来安装spyder。
