After installing PyCGNS python package from Anaconda distribution, I am not able to open CGNS files as recommended in the following pages using the command line CGNS.NAV or cg_look:

Browsing your CGNS tree with NAV

Here is the error message I am receiving whether I am running the command line in Git Bash, Powershels, or CMD:

CGNS.NAV: FATAL error, cannot import qtpy.QtCore...

Hints:

pyqt5 is already installed
print(sys.path)

您需要安装PYQT。
从Anaconda Navigator（在主菜单中）打开CMD.EXE提示。

执行此命令：

conda install pyqt5

如果您已经安装了它，则可能不在您的环境中。

请发布以下输出：

print(sys.path)

找出安装pyqt5的位置，然后将其广告到您的路径驱动器上。您会在互联网中找到Howto的大量。这是其中之一（来源： https://www.educative.io/edpresso/how-to-to-add-python-to-path-path-variable-in-windows ）：

Right-clicking This PC and going to Properties.

Clicking on the Advanced system settings in the menu on the left.

Clicking on the Environment Variables button on the bottom right.

In the System variables section, selecting the Path variable and clicking on Edit. The next screen will show all the directories that are currently a part of the PATH variable.

Clicking on New and entering Python’s install directory.

You need to install PyQT.
Open the cmd.exe prompt from the anaconda navigator (in the home menu).

Execute this command:

conda install pyqt5

If you already had install it, maybe it's not in your enviroment.

Please post the output from:

print(sys.path)

Find out where PyQt5 is installed and ad it to your path-enviroment. You will find plenty of howto's in the internet. Here is one of them (Source: https://www.educative.io/edpresso/how-to-add-python-to-path-variable-in-windows):

Right-clicking This PC and going to Properties.

Clicking on the Advanced system settings in the menu on the left.

Clicking on the Environment Variables button on the bottom right.
