Yep, as I wrote in my comment above, there seems to be a dependency-override when the requirements.txt
states different than the dependencies in the packages. In my case installing the package manually also installed the (newer) version of requests
, namely 1.2.0. Using the requirements.txt
always installed (due to the override) the version 0.14.2 of requests
.
Problem solved by updating the requests
version in the requirements.txt
:-)
