无法在 ubuntu 中捆绑安装 json gem

Question

我已经使用 rvm 在 rails 上安装了 ruby​​。我正在尝试捆绑安装我在以前的电脑上安装的旧项目，但是当我运行 bundle install 命令时出现以下错误：

Installing json 1.8.3 with native extensions

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

    /home/florin/.rvm/rubies/ruby-2.2.3/bin/ruby -r ./siteconf20151003-5986-vme5ji.rb extconf.rb

An error occurred while installing json (1.8.3), and Bundler cannot continue.
Make sure that `gem install json -v '1.8.3'` succeeds before bundling.

阅读互联网我尝试安装所有开发人员，例如：
sudo apt-get install libpq-dev

sudo apt-get install libmysqlclient-dev
sudo apt-get install libpq-dev
sudo apt-get install libsqlite3-dev
sudo apt-get install libev-dev

但它没有用。

Answer 1

/usr/bin/ld: cannot find -lgmp意味着链接器尝试链接lgmp但找不到它。

解决方案：安装需要的库： sudo apt-get install libgmp3-dev
