Running bash on heroku won't work
提问by E.S.
I am trying to run bash on heroku to test it out and it is failing
我正在尝试在 heroku 上运行 bash 来测试它，但它失败了
$ heroku run bash ? Error: No app specified ? Usage: heroku run --app APP ? We don't know which app to run this on. ? Run this command from inside an app folder or specify which app to use with --app APP ? ? https://devcenter.heroku.com/articles/using-the-cli#app-commands $ heroku run --app bash ? Usage: heroku run COMMAND ? ? Example: heroku run bash
$ heroku run bash ? Error: No app specified ? Usage: heroku run --app APP ? We don't know which app to run this on. ? Run this command from inside an app folder or specify which app to use with --app APP ? ? https://devcenter.heroku.com/articles/using-the-cli#app-commands $ heroku run --app bash ? Usage: heroku run COMMAND ? ? Example: heroku run bash
So, the example says heroku run bashwill work but it doesn't. I have no dynos running. I feel I am missing something basic here...
所以，这个例子说heroku run bash会起作用，但它不会。我没有运行 dynos。我觉得我在这里缺少一些基本的东西......

Try run commands:
尝试运行命令：
First you need to login, then you to see your apps and finally run bash
首先你需要登录，然后你才能看到你的应用程序，最后运行 bash
$heroku login
Insert you user and password
输入您的用户名和密码
$heroku apps
=== [email protected] Apps
myaplication
then look at the list aps and write
然后查看列表aps并写
$heroku run bash --app myaplication

I think you have two issues.
我认为你有两个问题。
Firstly, you need to run bash within some app. You can either specify the app via the --app key as the help actually says or you can run this command inside the folder which has a heroku app initialized already. For connecting the folder to a heroku app - see this answer How to link a folder with an existing Heroku app.
首先，您需要在某个应用程序中运行 bash。您可以通过 --app 键指定应用程序，如帮助实际所述，或者您可以在已初始化 heroku 应用程序的文件夹中运行此命令。要将文件夹连接到 heroku 应用程序 - 请参阅此答案How to link a folder with an existing Heroku app。
Second, running a bash actually takes away one dyno from your app. So you need to have at least one dyno.
其次，运行 bash 实际上会从您的应用程序中删除一个 dyno。所以你至少需要一个dyno。
