Problems ./script/server

Hey,

everytime i want to start the server i get the error2 below that there were problems with gems. So i update them with "gem update" and it works. But now i get the error1. In the environment i can set the gem_version to 2.3.5 but after that i will get error2 again. Put it to gm_version 3.0.0 i will get error1. I don´t know how to solve this. Could somebody help me? Thanks

ERROR1:
