[Python] CondaEnvException: Pip failed. I am getting a pip subprocess error when trying to...

I am trying to create an environment in conda using a .yml file. Here are the commands i have run,

git clone https://github.com/fastai/fastai
cd fastai
conda env create -f environment.yml


The last command gives me the error. Everything works fine until a certain point and then all of a sudden I get this :

Pip subprocess error:

I have tried the following things and continue to get the error mentioned above:

• Uninstall the environment and try again
• Update pip to the current version in all environments
• Run the Anaconda Powershell prompt as admin and try again

Can someone help in resolving this problem. I have no idea why this is happening so and explanation is also appreciated.
