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

git hash-object -w spec/routing/splits_routing_spec.rb

With this, git will make a Sha1 for the file.
