Module 'psconvert' failed with status code 79: psconvert [ERROR]: Cannot execute Ghostscript (gswin64c). #3366

Description of the problem

I have recently started a new job at a different university. Thus I need to re-install some python packages, including pygmt, on my new laptop. However, I got some errors when I tried to run my previous code. The error pops up upon calling fig.show(), please see the following example and the corresponding full error message. I am aware that this error has been discussed before. After going through the previous threads on this topic, I still cannot figure it out. I appreciate it if you could help me out.

I created an environment "pygmt_home" on my 64-bit windows laptop to demonstrate the issue. Some basic information:

What's the output if you run gswin64c --version or gswin64c.exe --version?

What's the output if you run gswin64c --version or gswin64c.exe --version?

It is 10.03.1, please see below:

This one is really hard to debug since we can't reproduce your issue.

Does fig.show(gs_path="C:\Users\MJDR5\AppData\Local\anaconda3\envs\pygmt_home\Library\bin\gswin64c") works?

Yes, it worked, both fig.show and fig.save. It seems I need to specify the path in both commands. Thank you so very much.

Good to know that it works. Closing.
