我通过切换到进程目录(我尝试使用inkscape)解决了我遇到的类似问题，它解决了我的问题

I solved a similar problem I had by switching to the process directory (I was trying to use inkscape) and it solved my problem

import subprocess
inkscape_dir=r"C:Program Files (x86)Inkscape"
assert os.path.isdir(inkscape_dir)
os.chdir(inkscape_dir)
subprocess.Popen(['inkscape.exe',"-f",fname,"-e",fname_png])

也许切换到进程目录也对你有用.

Maybe switching to the process directory will work for you too.
