Hi:

You're right, but at least we won't have to worry about this until “python3.10”

·         And we're comparing directory names, "Python 3.6.6" doesn't appear in the Python version we found

·         We find python applications using “whereis python”   “/usr/bin/python3.6” “/usr/local/bin/python3.6”

·         Later we can compare the form of string length to add a layer of judgment, but we don't need it now.


Any question, please let me know. Thanks.

Best Regards
Fan Zhiju

That's fine for now, hopefully it'll keep working as long as it needs to.

But once you're comparing for example 3.7 and 3.12:

[bcran@photon ~]$ if [[ "3.7" > "3.12" ]]; then echo "wrong!"; else echo "correct!"; fi
wrong!

[PATCH] BaseTools:Linux changes the way the latest version is judged

[Fan, ZhijuX]

[-- Attachment #1: Type: text/plain, Size: 1238 bytes --]

BZ:https://bugzilla.tianocore.org/show_bug.cgi?id=1929

Some Linux servers do not have BC installed,so errors occur.
So the judgment was changed to avoid this error.

I think using the "-lt" operator might be better (more standard). e.g.:


if [ "$origin_version" -lt "$python_version" ]; then
