grass7: ImportError: No module named wx

[stanimura]

grass7 @7.4.1 failed to build possibly due to the new Xcode.

$ xcodebuild -version
Xcode 10.0
Build version 10A255

Error appears to be:

Did you use the +gui variant?

[stanimura]

No. I did with no variants. It seems that grass7 may require WxPython even without +gui variant. After installing wxPython-3.0 @3.0.2_5, I retried the following command lines.

$ sudo port clean grass7 && sudo port -v install grass7 -gui

The import error of wx dispeared but grass7 still failed to build.

[stanimura]

grass7 @7.4.1_0 is now able to build on Mojave.

$ xcodebuild -version
Xcode 10.1
Build version 10B61

Thank you.

[mf2k (Frank Schima)]

I see, so Xcode 10.1 fixed a bug that allows this to work now.
