Go App Engine on macOS: Where Should I Install google-cloud-sdk and How Should I Configure GOPATH?

Troubleshooting App Engine Setup: Path Issues for google-cloud-sdk

Developers frequently face challenges when setting up Go App Engine on macOS. This article delves into a common issue related to the location of the google-cloud-sdk and the optimal configuration for GOPATH.

Background

The google-cloud-sdk package houses various tools and components for interacting with Google Cloud services, including App Engine. Users often wonder about the appropriate location for this package and how it relates to GOPATH.

Location of google-cloud-sdk

Unlike GOROOT or GOPATH, the google-cloud-sdk package should not reside in either of these directories. Instead, it should be extracted to the user's home directory (~). To execute the installation, run the installer. If necessary, add the google-cloud-sdk path to your PATH environment variable in your .bash_profile.

GOPATH Configuration

Contrary to common belief, do not modify your GOPATH to include the src directory in google-cloud-sdk/platform/google_appengine/goroot/src. This modification can disrupt the proper functioning of your setup. App Engine SDK for Go automatically utilizes the sources in this directory without requiring any manual manipulation.

Additional Points

• Avoid manually changing $GOROOT unless compiling a new Go version from source.
• If your installation becomes problematic, completely remove the cloud SDK, Go installation, and any references to them in your PATH. Reinstall both Go and the cloud SDK from scratch.
• Go source code for App Engine development should be placed in your regular $GOPATH, not in the google-cloud-sdk directory.
• Use dev_appserver.py to run the local development server. Specify the path to your project directory with the code and app.yaml.
• Refer to the provided documentation for deployment instructions.
