App Engine错误没有模块google.cloud.speech和appengine.api

Question

I'm using Google Cloud AppEngine based on the examples provided on Github I was testing the blobstore example but when I try to include the API google.cloud.speech in that example I get the error "No module named google.cloud.speech" but in the speech demo the same import it works.

dev_appserver.py app.yaml

In the speech demo when I include the import google.appengine.api I have the error No module named appengine.api, but the same import it works on the blobstore example.

python2.7 transcribeSpeech.py resources/audio.raw

First Error

You're mixing up standard env GAE apps (your 1st invocation) with standalone python apps (your 2nd invocation) - not the same thing, they don't work the same way, so don't make behaviour comparisons between them expecting to be the same/similar. See GAE works but import webapp2 failed in Spyder .

If your app is a GAE standard app (the only ones supported by dev_appserver.py ) then you have to vendor in all additional libraries inside your app (GAE doesn't know/care about libraries installed in your virtual env or your local python installation). See python google app engine stripe integration .

Each of the (standard env GAE) examples you're following contains a requirements.txt with the required libraries - that's the library you need to vendor in, don't just dump the entire example directory in your app and expect the examples to work (as the filepaths in your tracebacks appear to suggest). They're just independent snippets/examples, not a fully functional, ready-to-use app as a whole.
