Thanks for the report. This only happens on Python 2 and is unrelated to the activity-log list command. Until it is fixed, please run the following:

pip uninstall antlr4-python3-runtime
pip install antlr4-python2-runtime

That should unblock you while we investigate.

[tjprescott]

How did you install the CLI?

[tjprescott]

When the CLI is installed it should install the correct antlr runtime. It looks like in your case it did not.

I am receiving the same issue on centos 7 when I do pip install azure-cli. I tried uninstalling and reinstalling the different antlr runtimes and did not have complete success. Anything I can provide?

[tjprescott]

If you do a pip install into a clean virtual environment followed by pip list you should only see a single runtime (for Python2). Is that not the case?

[alanmbarr]

it seems like it resolved itself after reinstalling. thanks!

@tjprescott Just FYI, I've hit this issue with azure-cli 2.0.46 on macOS. Installed by running curl -L https://aka.ms/InstallAzureCli | bash as shown in https://buildazure.com/2017/05/25/install-azure-cli-2-0-on-macos/. The script creates a virtualenv in ~/lib/azure-cli.
