“bin/rails: 没有这样的文件或目录"带 Ruby 2 &Heroku 上的 Rails 4
在遵循 Michael Hartl 的 Ruby on Rails 教程，我的应用程序无法在 Heroku 上启动，但使用 bundle exec rails server 在本地运行良好.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 run bash 并检查 bin 目录，我可以看到 not 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?我完全按照教程操作.
What have I done wrong? I followed the tutorial exactly.
在为此苦苦挣扎之后，我注意到我的 Rails 4 项目有一个 /bin 目录，这与一些旧的 Rails 3 不同我克隆的项目./bin 包含 3 个文件，bundle、rails 和 rake，但这些文件没有进入 Heroku因为我的全局 .gitignore 文件中有 bin.
After struggling with this for a bit, I noticed that my Rails 4 project had a /bin directory, unlike some older Rails 3 projects I had cloned. /bin contains 3 files, bundle, rails, and rake, but these weren't making it to Heroku because I had bin in my global .gitignore file.
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，因此要解决此问题:
This is a pretty common ignore rule if you work with Git and other languages (Java, etc.), so to fix this:
- 从
~/.gitignore中删除bin - 运行
捆绑安装 - 提交您的更改为
git add .和git commit -m "Add bin back" - 使用
git push heroku master 将您的更改推送到 Heroku
- Remove
binfrom~/.gitignore - Run
bundle install - Commit your
changes with
git add .andgit commit -m "Add bin back" - Push your changes to Heroku with
git push heroku master
