Json -v 1.8.6 不会作为 capistrano 部署的一部分安装

Question

这个问题已在 Whosebug 和其他论坛上被问过几次，但我似乎无法通过我遇到的这个错误。当我运行 capistrano production deploy 时，我在部署过程中收到此错误。

cap production bundler:install
00:00 bundler:install
      01 bundle install --path /var/local/blackduck_flock_rails/shared/bundle --without development test --deployme…
      01 An error occurred while installing json (1.8.6), and Bundler cannot continue.
      01 Make sure that `gem install json -v '1.8.6'` succeeds before bundling.
(Backtrace restricted to imported tasks)
cap aborted!


SSHKit::Runner::ExecuteError: Exception while executing as serv-deployer@oh-utility01.dc1.lan: bundle exit status: 5
bundle stdout: An error occurred while installing json (1.8.6), and Bundler cannot continue.
Make sure that `gem install json -v '1.8.6'` succeeds before bundling.
bundle stderr: Nothing written


Tasks: TOP => bundler:install
(See full trace by running task with --trace)

我查看了我的 log/capistrano.log 文件，这里是我正在查看的相关内容以进行故障排除。

所以首先要注意。日志告诉我捆绑器的运行ning 版本已经过时，我应该安装最新的。这是我不明白的地方。在我的开发机器上，我有 Bundler version 1.14.6。在我尝试部署到的目标服务器上，我也有 Bundler version 1.14.6。我在两台机器上都确认过，确实是一样的。其次，对于开发机器和目标机器，我有相同的 ruby 版本。 ruby 版本为 2.2.5。

其次，当我在目标服务器上运行 gem list时，我可以看到安装了json 1.8.6。

json (1.8.3, 1.8.1)

什么给了？

最后，问题必须出在目标机器上的这个目录中/var/local/blackduck_flock_rails/shared/bundle。在 bundle 目录中，我有一个包含 1.9.1 和 2.2.0 的 ruby 文件夹。这可能是问题的根源。我对这个问题感到困惑，似乎像这样的问题总是与某人机器上不一定适用的特定问题有关。将不胜感激。

最可能的原因是您缺少一些 capistrano 无法安装的系统依赖项。

通过 Ssh 连接到您的服务器并尝试安装 sudo apt-get install libgmp3-dev

如果它不能解决问题，请再次 ssh 并运行 gem install json -v '1.8.6' 它告诉你的 post 你从这里得到的错误消息。

Json -v 1.8.6 不会作为 capistrano 部署的一部分安装

Json -v 1.8.6 will not install as part of capistrano deploy
