由于gem pg(0.18.4)，我无法进行捆绑安装 [英] I can't do bundle install because of gem pg(0.18.4)

问题描述

我在AWS上使用ec2，并尝试部署我的Rails应用程序.我成功git将我的应用程序克隆到了ec2-user上，然后尝试进行捆绑安装，但由于gem pg而无法正常工作.我不知道为什么我不能安装捆绑软件.我在堆栈溢出上尝试了几种解决方案，但是什么都没用.需要您的帮助.

I am using ec2 on aws and trying to deploy my rails app. I successfully git cloned my app to my ec2-user then tried bundle install but which didn't work because of gem pg. I don't know why I can't do bundle install. I tried several solutions on stack overflow but anything didn't work. need your help.

推荐答案

该错误在堆栈跟踪中可见:

The error is visible in the stack trace:

Can't find the 'libpq-fe.h header

您没有构建PG适配器所需的libpq标头.确保已安装PostgreSQL和dev依赖项(libpq-dev软件包).

You don't have libpq headers, required for building the PG adapter. Make sure you installed PostgreSQL and the dev dependencies (the libpq-dev package).

此外，您需要清理您的Gemfile.您有3个等效的group :development, :test do声明.

Also, you need to cleanup your Gemfile. You have 3 equivalent group :development, :test do declarations.

此外，您将Sqlite3和PG gem都导入到同一环境中.决定您的数据库，并只使用其中之一.

Plus, you import both the Sqlite3 and PG gems in the same envs. Take a decision about your database, and use only one of them.

最后但并非最不重要的一点是，您没有声明要用于生产的数据库，因此部署到生产将失败.

Last but not least, you have no database declared for production, hence your deployment to production will fail.
