SOLVED: Running gulp program shows missing uffmol4.lib file

Both libraries and Docs are added to the environment variables, and there is no problem running its example. But when I run my structural optimization file, I get an error. will show that the uffmol4.lib file is missing
When adding uffmol4.lib to the structure optimization folder, it works again.
Is there any way to solve this problem?
Am I compiling incorrectly or is there something wrong with the settings?

The reason this doesn’t work is because you’ve used the wrong environment variables. The correct ones are GULP_LIB and GULP_DOC, but you’ve added _PATH to them for some reason.

Thanks, I’ve got it. The reason is that a related program called in the script I wrote does not refer to the lib path of gulp. Thank you for your reply. Julian
