“bin / rails：没有这样的文件或目录” w / Ruby 2& Rails 4在Heroku上

问题描述

在遵循Michael Hartl的Rails 4 Beta 版本的 ，我的应用程序无法在Heroku上启动，但在本地使用 bundle exec rails rails 。检查 heroku logs -t 显示以下错误：

While following the Rails 4 Beta version of Michael Hartl's Ruby on Rails Tutorial, my app fails to start on Heroku, but runs fine locally with bundle exec rails server. Checking heroku logs -t reveals the following error:

$ heroku[web.1]: State changed from crashed to starting
$ heroku[web.1]: Starting process with command `bin/rails server
-p 33847 -e $RAILS_ENV`
$ app[web.1]: bash: bin/rails: No such file or directory
$ heroku[web.1]: Process exited with status 127
$ heroku[web.1]: State changed from starting to crashed
$ heroku[web.1]: Error R99 (Platform error) -> Failed to launch the
dyno within 10 seconds
$ heroku[web.1]: Stopping process with SIGKILL

如果我 heroku运行bash 并检查 bin 目录，我可以看到存在 a rails 可执行文件：

If I heroku run bash and check the bin directory, I can see that there is not a rails executable:

~$ ls bin
erb  gem  irb  node rdoc  ri  ruby  testrb

我做错了什么？我仔细地跟着教程。

What have I done wrong? I followed the tutorial exactly.

推荐答案

如果您使用Git和其他语言（Java等），这是一个非常常见的忽略规则，因此修复此问题：

This is a pretty common ignore rule if you work with Git and other languages (Java, etc.), so to fix this:

1. 从〜/ .gitignore bin >
   
2. 运行 bundle install


3. 使用 git提交
更改添加。和 git commit -m将bin添加回来


4. code> git push heroku master

1. Remove bin from ~/.gitignore
2. Run bundle install
3. Commit yourchanges with git add . and git commit -m "Add bin back"
4. Push your changes to Heroku with git push heroku master
