"捆绑器:命令未找到:独角兽"之后添加了Procfile,由Heroku Bamboo告知Cedar迁移指南

Question

正如Bamboo to Cedar迁移指南所述,我将其添加Procfile到我的Heroku应用程序中:

web: bundle exec unicorn -p $PORT -E $RACK_ENV -c config/unicorn.rb
worker: bundle exec rake jobs:work

然后我跑去bundle install推了推.现在服务器不再启动了:

我究竟做错了什么？

Answer 1

添加gem 'unicorn'到您的Gemfile,运行bundle install.提交更新的Gemfile和Gemfile.lock文件并将其推送到Heroku.
