Question

我无法在heroku上推送我的rails应用程序。以下是我尝试在heroku上推送rails应用程序时收到的错误消息。

检测到Ruby应用程序编译Ruby / Rails sh：1：Gemfile：找不到！！解析你的Gemfile时出错，我们无法继续！！ [！]解析Gemfile时出错：语法错误，意外 '：'，期待输入结束 - 组：生产做！ ^。捆绑无法继续。！！来自 / tmp / build_c114d933dd903e377866500bea22e827 / Gemfile：50！＃ -------------------------------------------！＃！＆GT;组：生产做！ #gem'pg'！＃ -------------------------------------------！！推送拒绝，无法编译Ruby应用程序。

这就是我的gemfile的样子。

group: production do

gem 'rails_12factor'
end

Answer 1

好的我明白了。由于您在gem文件中犯了两个错误，您收到此错误

（1）您忘记在gem文件中定义gem 'byebug'的版本。

（2）您写了group: production do，假设是group :production do我很确定您无法在本地运行您的应用，直到您解决这两个问题。

在您的gem文件中添加gem 'byebug', '3.4.0'。如果您只是在{gem}文件底部的第4行添加gem 'byebug'而不是'3.4.0'，那么您只有group :production do

一旦您将这些更改添加到您的gem文件，请确保您运行group: production do然后bundle install

成功完成上述过程后，您可以运行以下命令将您的应用程序上传到heroku。

bundle update

Answer 2

这是解析Gemfile的错误：语法错误，意外＆＃39;：＆＃39;，期待输入结束 - 组：生产

如上所述...这只是语法错误

group: production do
  gem 'pg'
  gem 'rails_12factor'
end

从

更新

group :production do
  gem 'pg'
  gem 'rails_12factor'
end

heroku无法部署我的应用程序
