Why is pip raising unrelated warning?

Question

I am using OS X, where I am running Python 3.6 applications. I have installed some AWS components using pip3 like awscli, boto3 etc...

Today I was trying to install schedule package using pip3 . I got the message below:

jaes-MacBook-Pro:Sample jaeraam$ pip3 install scheduleCollecting schedule  Downloading https://files.pythonhosted.org/packages/df/2c/3a94d846682a4fb94966e65bca19a1acb6f7dd85977f4e4cece6e677b757/
schedule-0.5.0-py2.py3-none-any.whl
awscli 1.15.16 has requirement botocore==1.10.16, but you'll have botocore 1.10.28 which is incompatible.
Installing collected packages: schedule
Successfully installed schedule-0.5.0

If you see the like 3, I am getting some weird error. I am fine with that, but why the package unrelated to the current installation is thrown in the console?

Answer 1

Presumably because a dependency of the package you are installing has botocore as its dependency. So the installer checks if all dependencies and their dependencies and so on are installed and whether they are compatible, in your case a dependency ( awscli ) is not compatible with your version (1.10.28) of its dependency botocore .
