[英]Command line gem install error - sqlite3 - Rails New Command
I tried creating a new rails application in command line and had the following error. 我尝试在命令行中创建新的Rails应用程序,并遇到以下错误。 What's the problem?
有什么问题?
I have tried working it out myself, but I'm new to coding and even reading through it I'm completely lost! 我已经尝试过自己解决问题,但是我是编码的新手,即使阅读它,我也完全迷失了!
