ImportError: No module named typing

I installed scan build after a clone from git repository and it was successful. But after that I tried to use it and I got an error:

What can be the problem?
System information: MacOS 10.13
Thanks for the report. I presume you were not install the dependencies of scan-build package. (That's what the error is about.) I would recommend to install it as it suggested in the readme file, since pip will ensure that dependencies are satisfied. (I would also suggest to use virtualenv or virtualenvwrapper instead of sudo install any software on you machine.)
I tried like as your wrote:
Baloghs-MacBook-Pro:scan-build tamasbalogh$ make intercept_build_venv
# Create a virtual environment which can be used to run the build package.
virtualenv -p python2 intercept_build && \
. intercept_build/bin/activate && pip install -r ./req

You are right, the dependency was not defined in the setup.py. Fixed , now version 2.0.10 works as simple as pip install scan-build.
For python3, it seems that typing is just a blank module that is left only for backwards compatibility and it's functionality is provided as part of the stdlib. Source: https://pypi.org/project/typing/
I've encountered this issue after packaging for Arch Linux while python-typing doesn't exist in the packages official repositories.
I think you should add a condition that will import the relevant stuff List, Any, Dict, Callable only when running with a python2 interpreter. Installing typing should be discouraged. This should be reopened.
Thanks for the update. Will work on it soon.
Fixed in version 2.0.14
