Setting up app engine for dart, gcloud preview error

Question

I'm having a problem setting up app engine development for dart

I was using
OS X 10.10
Dart SDK 1.11.1
Google Cloud SDK 0.9.67

Heres the error:

WC-Johndoe:dartsample Johndoe$ gcloud preview app run app.yaml

...........................................

since dart is a custom runtime, and the system tells you to use "--custom_entrypoint", did you try to run "gcloud preview app run app.yaml --custom_entrypoint"? — Patrice, Jul 03 '15 at 22:46
mine also returns "unrecognized arguments: --custom_entrypoint" — Miguel Fermin, Jul 07 '15 at 06:05

A quick look at this shows an issue with recent versions of Google's cloud SDK. Until further updates, there will be issues with using some other SDKs such as dart.

As mentioned in the link, in order to work around the issue, dial back the version of your Google cloud SDK using the commands in your terminal:

gcloud config set component_manager/fixed_sdk_version 0.9.64
gcloud components update

Revert to the current version of the cloud sdk via:

gcloud config unset --scope=installation component_manager/fixed_sdk_version
gcloud components update

According to https://groups.google.com/a/dartlang.org/forum/#!topic/cloud/J6LsrVVdJ6o

Setting the GAE_LOCAL_VM_RUNTIME environment variable to 0 should fix this

$ export GAE_LOCAL_VM_RUNTIME=0
$ gcloud preview app run app.yaml
