openGauss installation issue

Question

i am hitting an issue when installing openGauss:

File "/xxx/script/gspylib/os/gsfile.py", line 25, in <module>
raise Exception("[GAUSS-52200] : Unable to import module: %s." % str(e))
Exception: [GAUSS-52200] : Unable to import module: dynamic module does not define module export function (PyInit__psutil_linux).

I tried both python2 and python3, but didnt work. any suggestions?

Answer 1

The psutil is a 3rd party dependency. And this library will compile some binary dynamic-link libraries. As you see, the function PyInit__psutil_linux is an interface to initialize this library. I believe the incompatible Python version caused the error. I suggest for you:

1. Try to use a specific Python version to run the startup scripts. For example, the openGauss installation scripts rely on Python 3.6+.
2. Reinstall the psutil by using pip:

python3 -m pip uninstall psutil
python3 -m pip install psutil  # or psutil==xxx, give a specific version.
