为什么捆绑安装没有运行？

Question

所以诚然，这部分是我的错。 这一切都是因为我想安装引导程序而开始的。 我掉进了一个兔子洞，因为它最初不起作用，所以现在我在控制台中不断收到这些错误。

我现在要做的就是运行“捆绑安装”。 大约十五分钟前它工作得很好，现在我收到了这条消息：

    current directory: /home/ubuntu/.rvm/gems/ruby-2.6.3/gems/pg-1.1.4/ext

Could not create Makefile due to some reason, probably lack of necessary

        --with-pg-lib
        --without-pg-lib=${pg-dir}/lib

To see why this extension failed to compile, please check the mkmf.log which can be found here:

  /home/ubuntu/.rvm/gems/ruby-2.6.3/extensions/x86_64-linux/2.6.0/pg-1.1.4/mkmf.log

extconf failed, exit code 1

Gem files will remain installed in /home/ubuntu/.rvm/gems/ruby-2.6.3/gems/pg-1.1.4 for inspection.
Results logged to /home/ubuntu/.rvm/gems/ruby-2.6.3/extensions/x86_64-linux/2.6.0/pg-1.1.4/gem_make.out

An error occurred while installing pg (1.1.4), and Bundler cannot continue.
Make sure that `gem install pg -v '1.1.4' --source 'https://rubygems.org/'` succeeds before bundling.

In Gemfile:
  pg

所以然后我检查错误将我引导到的文件（ mkmf.log ），我收到了这个：

请帮忙，我快把头发扯掉了。 这非常令人沮丧。

Answer 1

从这里开始： https://wikimatze.de/installing-postgresql-gem-under-ubuntu-and-mac/

尝试以下操作：

sudo apt-get install postgresql
sudo apt-get install libpq-dev

然后再次尝试bundle install 。

Answer 2

本已经给出了答案（我认为）。 但是你提到了引导程序。

Rails 6 提供了一种新方法，允许您在应用程序中使用节点包。 这是使用 css 和 js 框架的“新方式”； 而不是旧的资产管道。 bootstrap gem 都试图让 bootstrap 更容易集成到资产管道中。

虽然旧方法仍然有效； 您可能想投资于学习新方法。 Have a look at https://hackernoon.com/integrate-bootstrap-4-and-font-awesome-5-in-rails-6-u87u32zd for some specifics in getting the bootstrap npm package into rails.

学习这种新方法不仅有助于未来证明您的开发，您还会发现，一旦您掌握了这种方法，您将能够为您最喜欢的 js/css 工具使用支持更好的 npm 包； 而不是等待宝石更新（如果它们存在的话）
