I don't known how to solve it. I search this problem on google, but find nothing useful. Can anyone help me?

Answer 1

I encountered the same problem.
StarUML version: 2.8.0
I installed successfully by manual.follow this:

1. Get an extension as a .zip file.
2. Extract the file on the extensions path.
/Users/<user>/Library/Application Support/StarUML/extensions/user for Mac OS.
C:\Users\<user>\AppData\Roaming\StarUML\extensions\user for Windows.
3. Check a folder in the extensions path and main.js file in the folder.
4. Restart StarUML.
