我可以从哪里设置环境v android studio中有一个版本，我是Windows用户

from where can i set environment variable in android studio, I am windows user

推荐答案

从错误

java.io.IOException：应用程序默认凭据不可用
。如果它们在Google Compute Engine中运行，则可用。
否则，必须定义环境变量GOOGLE_APPLICATION_CREDENTIALS
指向定义凭据的文件

java.io.IOException: The Application Default Credentials are not available. They are available if running in Google Compute Engine. Otherwise, the environment variable GOOGLE_APPLICATION_CREDENTIALS must be defined pointing to a file defining the credentials

您可能需要在环境变量路径 GOOGLE_APPLICATION_CREDENTIALS = path中添加它/to/your/service_accont_key_file.json 。并应从此处 https://cloud.google.com/docs/身份验证/入门。另外，如果您不知道如何设置环境变量路径，则可以检查此 https：// www .computerhope.com / issues / ch000549.htm

You may need to add this in the environment variable path GOOGLE_APPLICATION_CREDENTIALS=path/to/your/service_accont_key_file.json. And should get the json file from here https://cloud.google.com/docs/authentication/getting-started . Also if you don't know how to set environment variable path you can check this https://www.computerhope.com/issues/ch000549.htm
