git commit stopped working - Error building trees

Question

I can not commit a change:

$ git commit
error: invalid object 100644 13da9eeff5a9150cf2135aaed4d2e337f97b8114 for \'spec/routing/splits_routing_spec.rb\'
err         


        

Answer 1

This can be caused by some third-party synchronization APP such as Dropbox and Jianguoyun. There might be two ways based on my experience:

1. You can try to undo recent synchronization operations.
2. Remove the related files from the folder, commit, and then move back the files.
