gem 添加到 gemfile 和 bundle install 运行但仍然看到 Gem::LoadError: unicorn is not part of the bundle。将其添加到 Gemfile

Question

我正在使用 mina 进行部署。我在 Gemfile 中有gem 'mina-unicorn', :require => false（我尝试用gem 'unicorn' 替换上面的行）然后我做了bundle install。

当我运行 mina deploy --verbose 我看到bundler: failed to load command: unicorn (/home/deployer/.rbenv/versions/2.1.2/bin/unicorn) Gem::LoadError: unicorn is not part of the bundle. Add it to Gemfile.

gem 文件的路径设置不正确。

这是控制台输出

根据gemspec，mina-unicorn 没有 unicorn 依赖项，您必须在 Gemfile 中显式添加它

gem 'mina-unicorn', :require => false
gem 'unicorn'

此外，根据您的bundle install 输出，您可以判断出未安装独角兽。

更新：

米娜的作用是：

从您在config/deploy.rb 中指定的远程存储库中获取代码库，即https://kkteja@bitbucket.org/kkteja/salesforce_casts.git，从文件https://bitbucket.org/kkteja/salesforce_casts/src/ec42bcc304fb581f5b7a0a61b9c073f66b0dffac/Gemfile?fileviewer=file-view-default 中您可以看到，unicorn 不是。

虽然你在 Gemfile 中添加了它，但如果你不将更改提交到 bitbucket，它不会影响 mina deploy。

实际上，您不必手动将 repo 克隆到数字海洋，所有部署工作都可以在您自己的机器上完成。

更新：

确保您的 pid 文件和目录对于您的 deployer 用户是可写的，如日志所述。
