ruby-on-rails – Docker&Rails | bundler：找不到命令：rails_语言综合

概述我是Docker的新手,对Rails来说还是新手. 当我运行docker-compose时,我收到此错误： web_1 | bundler: command not found: railsweb_1 | Install missing gem executables with `bundle install`app_web_1 exited with code 127 最初我在运行bun 我是Docker的新手,对Rails来说还是新手.

当我运行docker-compose时,我收到此错误：

web_1  | bundler: command not found: railsweb_1  | Install missing gem executables with `bundle install`app_web_1 exited with code 127

最初我在运行bundle install时遇到任何gem都遇到了麻烦.我的Gemfile中的每一个Gem都出现了“找不到任何来源的宝石”的错误.然后我尝试运行bundle(没有安装),它没有返回任何错误.

Rails肯定是安装的,因为输入rails给了我所有的使用选项.

此外,我可以看到供应商/缓存中的宝石.我尝试删除所有这些并运行bundle install,当捆绑器安装它们时,它们都开始逐个出现.

编辑：请随意纠正我的理解：因为运行bundle install意味着在Docker实例上安装gem,它不是“本地”安装的.在尝试解决此问题时,我在本地删除了所有宝石并重新安装了bundler.所以,当我运行gems List时,我只看到bundler.我运行了bundler install,它声称正在安装所有的gem.他们在哪里安装？它说这是供应商/缓存,这是真的.我可以在那里看到它们,但它仍然找不到任何宝石：它甚至找不到铁轨.

编辑2：我还应该提一下：bin / rails s启动服务器就好了.由于数据库实例没有运行,它不会加载任何东西,但我认为这是有道理的.

编辑3：我在本地运行gem install rails,仍然没有变化,但现在gems List返回rails及其依赖项.

下面是一些下面可能相关的文件和日志,可以帮助确定原因.请注意我将实际的应用程序名称更改为app.

运行gems列表返回：

我的Dockerfile看起来像这样：
