ERROR: Cannot install -r requirements_mapping.txt (line 21) and MarkupSafe==1.1.1 because these package versions have conflicting dependencies.
The conflict is caused by:

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict
