我找到了这个问题的解决方案。我没有在我的 firebase 云函数中上传 vision-annotate-images。
To deploy the function:
Clone or download the functions-samples repo and change to the vision-annotate-image directory:
git clone https://github.com/firebase/functions-samples
cd vision-annotate-image
Install dependencies:
cd functions
npm install
cd ..
If you don't have the Firebase CLI, install it.
Initialize a Firebase project in the vision-annotate-image directory. When prompted, select your project in the list.
firebase init
Deploy the function:
firebase deploy --only functions:annotateImage
