当我尝试 gem intall 时,我不断收到如下错误:
ERROR: Could not find a valid gem 'ruby-gmail' (>= 0), here is why:
Unable to download data from https://rubygems.org/ - SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (https://s3.amazonaws.com/production.s3.rubygems.org/latest_specs.4.8.gz)
对于我的生活,我不知道为什么会这样。我以前没有问题。
