zsh:1：找不到命令：rake

Question

我尝试在 Capistrano 的部署中执行 rake，但我发现执行时出现问题，因为 ZSH。

zsh:1: command not found: rake

所以我从我的机器上删除了ZSH，但同样的问题仍然存在。

config/deploy.rb

desc 'My task'
task :my_task do
  on roles(:app) do
    execute 'rake my:task'
  end
end

日志：

00:00 deploy:my_task
      01 rake my:task
      01 zsh:1: command not found: rake

这与zsh无关；相反，似乎在环境的路径中找不到 rake。三个选项：

1. 您没有安装 rake。 （只需安装它：gem install rake）
2. 您已安装它，但它不在 $PATH 中。 （添加到路径：export PATH=$PATH:/usr/local/bin/:)
3. 您已将它安装在 $PATH 中，但没有执行它的权限。 (chomd +x 耙子)
