  Invalid requirement while trying to use pip options
  Hi!
  
  I have in my pip section inside envrionment.yaml file this line
  ```- rep --install-option='--no-deps'```
  
  while I am trying to update my environment I am getting this error
  
  ```Invalid requirement: 'rep --install-option='--no-deps''```
  
  if I do pip -r requirements.txt and I have that line as it is in requirements.txt it works.
