Homebrew Installed Azure CLI not working - ValueError: field 6 out of range (need a 48-bit value)

Having installed azure-cli via homebrew I get the following python errors whenever I try and run a command. e.g. if I perform az login, or az --help, or other commands I get the following errors:-

$ az login field 6 out of range (need a 48-bit value) Traceback (most recent call last): File “/usr/local/Cellar/azure-cli/2.0.23/libexec/lib/python3.6/site-packages/azure/cli/main.py”, line 36, in main cmd_result = APPLICATION.execute(args) File “/usr/local/Cellar/azure-cli/2.0.23/libexec/lib/python3.6/site-packages/azure/cli/core/application.py”, line 141, in execute self.refresh_request_id() File “/usr/local/Cellar/azure-cli/2.0.23/libexec/lib/python3.6/site-packages/azure/cli/core/application.py”, line 269, in refresh_request_id self.session[‘headers’][‘x-ms-client-request-id’] = str(uuid.uuid1()) File “/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/uuid.py”, line 606, in uuid1 clock_seq_hi_variant, clock_seq_low, node), version=1) File “/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/uuid.py”, line 168, in init raise ValueError(‘field 6 out of range (need a 48-bit value)’) ValueError: field 6 out of range (need a 48-bit value)

Environment summary

Install Method (e.g. pip, interactive script, apt-get, Docker, MSI, edge build) / CLI version (az --version) / OS version / Shell Type (e.g. bash, cmd.exe, Bash on Windows)

I installed via home-brew, having initially tried to install using the curl method, however this failed to build. The home-brew version installed fine, but just doesn’t work.

Currently the upstream Python issue has been fixed and merged (1). Unfortunately a new 3.6 release (3.6.5) is not due until the end of March 2018 (2).

Workaround for Python 3.6.4

A risky workaround is possible manually substituting the uuid.py module in your local installation of Python 3.6.4.

1. download the patched uuid.py from the approved PR: https://raw.githubusercontent.com/bbayles/cpython/d4b98dff3441c79fb7c2af9149b96f819d0c81ab/Lib/uuid.py
2. go to the proper library folder for your Python 3.6.4 installation. In my case is /usr/local/Cellar/python3/3.6.4_2/Frameworks/Python.framework/Versions/3.6/lib/python3.6;
3. make a copy of uuid.py: cp uuid.py uuid.py.orig;
4. substitute the file with the one download: cp /your/download/path/uuid.py ./uuid.py;
5. profit (az login and other az should now works as expected).

Created a PR that will switch to uuid4 if uuid1 raises the ValueError.
