我该怎么做才能解决这个问题?
看起来你的来源要么没有正确回应,要么在源头找不到宝石。
尝试gem install rack-test
。 如果这给你一个错误,请尝试切换你从中得到宝石的来源。
首先添加源gem source -a 'https://production.cf.rubygems.org'
然后再次尝试安装。
要么
您可以尝试使用gem install rack-test --source 'https://production.cf.rubygems.org'
直接从其他来源gem install rack-test --source 'https://production.cf.rubygems.org'
一旦您正确安装该gem,请尝试再次安装rails。
