Exception raised during installation: Invalid requirement, parse error at "'; extra '"

[Samahu]

Getting the following exception when executing "conda env create -f environment.yml"

I am running on a new Windows 10 machine (all updates applied). I was able to reproduce the issue on a VM running Windows 10 too.

I ran into the issue using miniconda version 3.5.4 and also 3.5.11, which comes with pip 10.0.1.

CondaValueError: pip returned an error


(base) D:\udacity\RoboND-Python-StarterKitCopy>

After this the RoboND environment is created, however, when I try to run notebook I get errors that tensorflow is not found.

[Samahu]

Possible workaround

I have found this to be a working solution for me:

After you get the failure message, activate the incomplete environment:
(base)> activate RoboND

Within the RoboND env run the following command:
(RoboND)> conda update --all

Then individually install tensorflow using pip:
(RoboND)> pip install tensorflow==1.2.1

Then jupyter notebook should work as expected.

Same with me! Installing TF separately works!
