ChimeraX fails to start after failed bundle install

[tic20@…]

Copying email from a user below. He later reported that clearing the cache directory and reinstalling ISOLDE fixed the issue. He suspects that his VPN dropped out in the middle of the ISOLDE installation, and that before he deleted the ISOLDE installation directory ChimeraX would simply refuse to start without returning any error message.



 Hi Tristan,

I just tried installing ISOLDE on my Mac (using ChimeraX 0.8), and the result was that I was no longer able to launch ChimeraX.

So I tried removing any trace of ISOLDE, but something is still wrong: when I double-click on ChimeraX icon it keeps not launching, whereas if I start it from a shell by typing /Applications/ChimeraX.app/Contents/MacOS/ChimeraX then it launches, but types:

Fixed in b3d8cadc2.

If cache data is not consistent with installed bundles, ignore cache data.
