Puma在尝试使用capistrano安装时始终失败，但是当我尝试使用capistrano在当前目录中使用的相同命令时，puma启动成功。
bundle exec puma -C /home/deploy/apps/petfriend/shared/puma.rb --daemon

Tasks: TOP => puma:start
任何线索？
答案 0 :(得分：1)
我认为是因为
01 bash：bundle：command not found
问题在于捆绑，而不是puma
请尝试：
gem install bundler
在您应用的目录

尝试在服务器上的文件~/.bashrc底部添加这些行：
export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"
export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"
