I am developing a pure-python extension of Slicer. It is, at this point, private, so I cannot distribute it through the general extension server, and I have distributed it internally as a zip file. Most users are on Windows, and had no issues, but on a Mac the extension could not be installed.
This is not the issue of 3D slicer for MAC cannot install slicer extensions – extensions from the manager are installed with no problem; but when trying to install the Zip file, we get
ctk::copyDirRecursively: Failed to copy nonexistent directory "/Applications/Slicer.app/Contents/Extensions-30893/MyExtension/30893-macosx-amd64-MyExtension-git8bf4715-2022-08-22/Slicer.app/Contents/Extensions-30893/MyExtension" Failed to copy directory /Applications/Slicer.app/Contents/Extensions-30893/MyExtension/30893-macosx-amd64-MyExtension-git8bf4715-2022-08-22/Slicer.app/Contents/Extensions-30893/MyExtension into directory /Applications/Slicer.app/Contents/Extensions-30893/MyExtension-XXXXXX
(30893 is the build number for Slicer 5.0.3, I’ve replaced my real extension name with “MyExtension” here)
I have constructed the zip file “manually” – its contents are
+ 30893-macosx-amd64-MyExtension-git8bf4715-2022-08-22 | + lib | + Slicer-5.0 | + qt-scripted-modules | MyExtension.py | + share | + Slicer-5.0 | CMakeLists.txt | MyExtension.s4ext
What am I doing wrong?
