ruby-on-rails - "bundler: command not found: unicorn"在将 Heroku Bamboo 告知的 Procfile 添加到 Cedar 迁移指南之后

Question

正如 Bamboo 到 Cedar 迁移指南所述，我将此 Procfile 添加到我的 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

然后我运行 bundle install 并推送。现在服务器不再启动:

我做错了什么？

Answer 1

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