我正在尝试在新机器上运行 bundle install。我刚刚安装了 postgres.app 并重新启动了终端。在我的应用程序中运行 bundle install 会返回此错误。

    【解决方案1】:

    我认为,如果您安装此软件包 libpq-dev,它会有所帮助。你可以像这样安装它:sudo apt-get install libpq-dev。如需更多信息,您也可以查看此网站:https://gorails.com/setup/ubuntu/15.04

    【讨论】:

    • 感谢您的回答,但我收到“apt-get: command not found”错误
    • 我假设,您的 OS 是基于 Debian 的。这就是为什么如果你想安装那个包,你必须运行apt-get。无论如何,根据你正在运行的OS,你可以相应地修改命令。
