gcloud stop working - "was unexpected at this time."

This is a known issue that is being tracked here

After hours of trying to fix it! I found how :)

1. uninstall google SDK
2. https://dl.google.com/dl/cloudsdk/channels/rapid/google-cloud-sdk.zip
3. https://cloud.google.com/sdk/docs/downloads-interactive#interactive_installation

This fix the bug.

After that I had new bug in pyCharm GAE:

ImportError: No module named _subprocess

I fix this with the solution here: Error importing built-in module "_subprocess" using Google Cloud Platform's Local Development Server

Hope this helps and saves a lot of trouble for you guys :)

As noted in the other answers, this is a bug with the 274.0.0 version of gcloud. Another report of this issue actually identifies where the bug is and offers this fix:

If you are stuck and need an immediate solution, here's a workaround that will move you forward, but you should reinstall the Cloud SDK from scratch when a fix is ready.

1. Open C:\Program Files (x86)\Google\Cloud SDK\google-cloud-sdk-bin\gcloud.cmd in your editor
2. Near line 170, change ) ELSE ( to be just )
3. Remove the ) on the last line in the file.

That should get you working in the short term (albeit with an extraneous error message every time you run a command). After getting it working you can revert to version 273.0.0 (so that you stop getting the error message and aren't using a modified version) using:

gcloud components update --version=273.0.0

This is being tracked in the public bug https://issuetracker.google.com/issues/146458519

We have a patch for two files that are causing these problems. These apply in two cases (both on Windows): 1. A new install fails, or 2. You are unable to run gcloud after performing a components update.

For case # 1, please download the attached file install.bat, and copy it to the location where you have attempted to install gcloud, e.g. C:\Program Files (x86)\Google\Cloud SDK\google-cloud-sdk. Then run it, e.g.

cd C:\Program Files (x86)\Google\Cloud SDK\google-cloud-sdk .\install.bat

For both cases #1 and #2, download the attached file gcloud.cmd, and copy it to the bin directory under your gcloud installation, e.g. C:\Program Files (x86)\Google\Cloud SDK\google-cloud-sdk\bin. When prompted to replace the previous copy, type Yes. This should allow you to run gcloud without being prompted to set CLOUDSDK_PYTHON.

The files are attached in the public bug tracker.
