az component update --add fails with uninformative error

[itowlson]

I am using CLI 0.1.1b3 on Windows. It has the component module v0.1.0rc2 installed. When I run az component update --add redis it fails with the following error:

An error occurred. Run command with --debug for more information. If executing az with sudo, you may want sudo's -E and -H flags.

az --version output:

Running component update with the --debug flag produces the output in the attached file.

I am running as admin (elevated command prompt).

@itowlson thanks for including the attached file.

pip.basecommand : Cannot remove entries from nonexistent file c:\users\itowlson\appdata\local\continuum\anaconda3\lib\site-packages\easy-install.pth

Looks like the error is in this line.

This has been reported in Anaconda - ContinuumIO/anaconda-issues#542. There's lots of discussion on that issue but one of these commands may help.

conda update setuptools

suggested at ContinuumIO/anaconda-issues#542 (comment)

pip install --ignore-installed --upgrade pip setuptools

suggested at tensorflow/tensorflow#3324 (comment)

@derekbekoe Thanks for the quick and detailed response. After running (both) those commands, I still get the same "An error occurred" message, but the detailed trace is different (attached if you want to take a look). This looks more like it may be related to Azure CLI components. But perhaps it is a cascading effect of an underlying Anaconda bug. Should I consider uninstalling Anaconda and installing raw Python instead?

You have run into this #1221.

Windows has a file path length of 260 chars.
Anaconda attempts to write a file to 'C:\Users\itowlson\AppData\Local\Temp\pip-y1fv359h-uninstall\users\itowlson\appdata\local\continuum\anaconda3\lib\site-packages\azure\cli\command_modules\network\mgmt_express_route_circuit\lib\models\__pycache__\express_route_circuit_creation_client_enums.cpython-35.pyc' which is 265 chars long.

Oh, man. That makes sense. I'll see if I can get things to install further up the tree. Thanks.

Closing issue.
@itowlson please open another issue if you run into any further problems.
Thanks.
