如何修复捆绑器在 docker 容器中找不到 Rails

Question

我正在尝试在Docker容器中运行Blazer并收到错误。

运行后

docker-compose up --build

它构建但随后出现错误

bundler: command not found: rails
Install missing gem executables with bundle install

我做错了什么？

这是我终端中的错误：

Answer 1

该存储库不包括 Rails。

我想你想检查开拓者开发项目中的安装细节。

Answer 2

他们 Blazer 的作者为 Blazer Docker 创建了一个新项目： https://github.com/ankane/blazer-docker
