macOS High Sierra 10.13.6
After installing Command Line Tools (macOS 10.13) for Xcode 10 above
I installed Xcode10, but when I started it
loading a plug-in failedIs displayed and cannot be opened.
After checking the correspondence table, I think that even this OS version can install up to Xcode 10.1,
I checked it, but I don't know.
Answer # 1
It was a bug in the Macbook itself.
Thank you very much.
Answer # 2
What version of Xcode 10 are you trying to install?
Only Xcode 10.1 is supported on macOS High Sierra.
Xcode 10.2 does not support macOS High Sierra as it requires macOS Mojave 10.14.3 or higher.
Answer # 3
Have you tried installing Xcode by erasing Command Line Tools in?
When you install Xcode, Command Line Tools for that Xcode will be included automatically, so please try it.
Answer # 4
The final method is to do a clean install of the OS and then install Xcode.
Or try downloading Xcode to install again.
Answer # 5
I'm getting an error message saying that the plugin is failing to load. Are you using any Xcode plugin?
If you've used it before but aren't using it now, is it possible that the plugin wasn't uninstalled properly and is left in the trash?
To be on the safe side, we recommend that you check if there are any files in the plugins folder, delete them all, and then reinstall.
