回溯的上述部分很好地解释了问题，以及解决方案。
您似乎已将 pg gem 添加到您的 Gemfile，但尚未在 运行 bundle install 之后提交 Gemfile.lock 中的更改。
bundle install
git commit -am "Changes to Gemfile.lock after including pg gem"
git push origin master
cap production deploy
应该可以解决问题并成功完成部署。

回溯的上述部分很好地解释了问题，以及解决方案。
您似乎已将 pg gem 添加到您的 Gemfile，但尚未在 运行 bundle install 之后提交 Gemfile.lock 中的更改。
bundle install
git commit -am "Changes to Gemfile.lock after including pg gem"
git push origin master
cap production deploy
应该可以解决问题并成功完成部署。
