我正在使用运行8.1的Windows PC并使用Ruby Installer 2.1.5.

安装gem时我收到一个错误:

C:\> gem install bundle
ERROR:  Could not find a valid gem 'bundle' (>= 0), here is why:
          Unable to download data from https://rubygems.org/ - SSL_connect retur
ned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (
https://api.rubygems.org/latest_specs.4.8.gz)

我希望有一个很好的解决方案.

我很好奇有关雄辩如何知道它应该通过运行来保存我们给它的记录$ php artisan tinker.我实际上并不记得设置这么一个选项.

我是 Elixir 和 Phoenix 的新手。我试图为几个迁移文件运行迁移，mix ecto.migrate但它抛出了这个错误，
