Ruby on rails 错误：无法生成gem本机扩展

在我的ubuntu系统上安装了PostgreSQL，当我尝试运行

bundle install

时，我得到了以下错误

有没有办法运行该命令并安装所有必要的gems

-- gem install pg -v '0.18.4'

我也跑了

sudo-apt-get-install-gcc

---

并确保编译器是最新版本。

查看消息检查libpq fe.h。。。没有

尝试安装libpq-dev。 对于Ubuntu系统：

sudo apt-get install libpq-dev

---

然后您应该能够运行bundle安装。

我收到了相同的错误，但有以下消息：

正在检查pg_配置。。。没有

因此，根据上述解决方案，我运行如下：

dnf install libpq-dev   (Since I am using Fedora 23)

但有一个问题：

没有可用的程序包libpq dev。错误：找不到匹配项

postgresql最初是通过以下命令安装的：

dnf install postgresql-server postgresql-contrib

当我做了

哪个pg_config

，我得到了这个：

/usr/bin/which:中没有pg_配置 （/usr/local/heroku/bin:/usr/local/rvm/gems/ruby-2.2.4/bin:/usr/local/rvm/gems/ruby-2.2。4@global/bin:/usr/local/rvm/rubies/ruby-2.2.4/bin:/usr/lib64/qt-3.3/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/usr/local/rvm/bin:/home/mayur/.local/bin:/home/mayur/bin）

因此，我使用以下命令再次安装了postgresql：

dnf install postgresql-devel

现在运行

哪个pg_config

，输出

/usr/bin/pg_config

然后尝试

捆绑安装
：

安装带有本机扩展的pg 0.18.4…没有任何错误。
您安装了
libpq dev
吗？不确定，但如果您使用Alpine linux（在我的例子中是Docker映像），这看起来像是类似问题的重复，您应该安装postgresql dev<代码>apk添加postgresql开发
