Ruby on rails 使用捆绑安装时将rails应用程序部署到服务器时出错

我有一个rails应用程序，我想在docker容器中运行它

我已经运行了bundle安装。。但我犯了这个错误：

Gem:：Ext:：BuildError:错误：无法生成Gem本机扩展

Gem files will remain installed in     /var/www/test/xyz/vendor/bundle/ruby/2.2.0/gems/json-1.7.7 for inspection.

An error occurred while installing json (1.7.7), and Bundler cannot continue.
Make sure that `gem install json -v '1.7.7'` succeeds before bundling.

如何在/vendor/bundle中安装json gem

gem安装json-v1.7.7--path/vendor/bundle

---

不工作路径参数不允许

我也犯了同样的错误。这个错误是因为我们使用的ruby软件（gems）的版本在某些点上不匹配

您使用的是ruby版本2.2.1。您的Gemfile包含旧版本的gems，它依赖于json版本1.7.7

您应该安装以下ruby版本：

ruby-1.9.3-p448

---

要消除错误，或者更新与ruby 2.2.1版兼容的gems，就可以了。

运行

rm/var/www/test/xyz/vendor/bundle/ruby/2.2.0/gems/json-1.7.7

，然后

gem安装json-v'1.7.7'

然后我得到了这样一个结果：您没有/usr/local/rvm/gems/ruby-2.2.1目录的写入权限。您可以更改目录权限。我已经将777设置为/usr/local/rvm/gems/。。。但同样的错误也适用于我：sudogem安装json-v'1.8.2'
