zsh：1：找不到命令：rake

Question

I was trying execute rake in my deploy with Capistrano but I found a problem to execute because ZSH .

zsh:1: command not found: rake

So I remove ZSH from my machine but the same problem persist.

config/deploy.rb

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

Log:

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

This has nothing to do with zsh; rather, it simply seems like rake can't be found in the environment's path. Three options:

1. You don't have rake installed. (just install it: gem install rake)
2. You have it installed, but it is not in the $PATH. (add it to path: export PATH=$PATH:/usr/local/bin/:)
3. You have it installed and in the $PATH, but don't have permission to execute it. (chomd +x rake)
