Pip install failed to install/update network module due to Windows long paths

[Teodelas]

With a fresh install of Python and AZ CLI 2.0, az network commands fail. I get a message to run az component update --add network but that fails as well. When I add the debug switch I get:

Exception:
Traceback (most recent call last):
File "C:\Users\teodelas\AppData\Local\Programs\Python\Python35\lib\shutil.py", line 538, in move

Can you show the output of az --version? Additionally, how did you install the CLI?

This is on a Windows machine btw: $ az --version azure-cli (2.0.1) acr (0.1.1b2) acs (2.0.1) appservice (0.1.1b6) batch (0.1.1b5) cloud (2.0.0) component (2.0.0) configure (2.0.1) container (0.1.1b4) context (0.1.1b2) core (2.0.1) documentdb (0.1.1b2) feedback (2.0.0) find (0.0.1b1) iot (0.1.1b3) keyvault (0.1.1b6) network (0.1.1b2) nspkg (2.0.0) profile (2.0.1) redis (0.1.1b3) resource (2.0.1) role (2.0.0) sql (0.1.1b6) storage (2.0.1) vm (2.0.1) Python (Windows) 3.5.2 (v3.5.2:4def2a2901a5, Jun 25 2016, 22:18:55) [MSC v.1900 64 bit (AMD64)]

The version of the network package you have is incorrect. The latest version is 2.0.1--yours shows 0.1.1b2.
How did you install the CLI? Please try running pip install azure-cli-network --upgrade to see if it updates to the latest version.

The failure of az component update was due to this issue on Windows with long file paths #1221.

[tjprescott]

@derekbekoe is there any reason why pip would install anything but the latest?

[Teodelas]

Aha! That worked. Thank you! Can we add that to the troubleshooting documentation? https://docs.python.org/3/using/windows.html#removing-the-max-path-limitation
