如何在我的Websockets文件中添加-a -app? [英] How to add -a -app in my Websockets file?

问题描述

在Heroku上上传项目时遇到问题.我正在尝试更改socket.io和MongoUrl的值，但出现此错误:

I've got a problem when I upload my project on Heroku. I've trying changing value of socket.io and MongoUrl, but I get this error:

Error: Missing required flag:
›     -a, --app APP  app to run command against

推荐答案

这与您的任何文件都没有关系.您必须向Heroku CLI本身提供一个参数，例如

This has nothing to do with any of your files. It's an argument that you must provide to the Heroku CLI itself, e.g.

heroku config:set SOME_VARIABLE=some_value -a myapp

其中myapp是Heroku应用程序的名称.

where myapp is the name of your Heroku app.

如果heroku无法确定要连接的应用程序，则可能需要-a/--app自变量，原因是没有配置否 Heroku远程，或者是因为配置了一个Heroku遥控器.

The -a / --app argument is required when heroku can't figure out what app to connect to, either bcause there is no Heroku remote configured or because there is more than one Heroku remote configured.

另请参见如何在heroku CLI中避免使用--app选项?
