ruby-on-rails - heroku pg :psql error: cannot load such file -- dl/import (LoadError)

Question

我正在尝试使用 Windows 命令行中的以下命令访问 heroku 上的生产 postgresql 数据库:

> heroku pg:psql

但是，我收到以下错误。我使用 gem 'net-ssh', '2.9.3.beta1' 确保 net-ssh 包含在我的 gemfile 中，然后我删除了 gemfile.lock，并重新部署。感谢您的帮助!

我想通了。它与我在安装 Heroku 工具带后安装的 Ruby 版本有关。所以我像这样卸载并重新安装了 Heroku 工具带:

1. 转到添加/删除程序并卸载 Heroku Toolbelt
2. 从 https://toolbelt.heroku.com/ 安装 Heroku 工具带
3. 在命令行中输入 heroku 以安装 toolbelt

我希望这对某人有帮助。
