当我尝试运行工头时，我收到以下消息：
$ foreman start
00:29:24 worker.1 | started with pid 44135
00:29:24 mailcatcher.1 | started with pid 44136
00:29:24 worker.1 | /usr/local/foreman/bin/foreman-runner: line 41: exec: sidekiq: not found
00:29:24 mailcatcher.1 | /usr/local/foreman/bin/foreman-runner: line 41: exec: mailcatcher: not found
00:29:24 mailcatcher.1 | exited with code 127
00:29:24 system | sending SIGTERM to all processes
SIGTERM received
00:29:24 worker.1 | exited with code 127
我尝试重新安装工头 gem，但没有任何变化。我似乎无法找出谷歌上的错误或为什么找不到 sidekiq 和 mailcatcher。宝石被捆绑和安装。
