There are some earlier questions, most notably this, but they didn't help me. I am trying to install llvm version 10 (or 9) because it is a dependency for the pyod Python package. When trying to install, I get this error:
(.venv) user@desktop:/media/Projects/outliers$ pip install llvmlite

I believe the most important line is this:
RuntimeError: Building llvmlite requires LLVM 10.0.x or 9.0.x, got '6.0.0'. Be sure to set LLVM_CONFIG to the right executable path.
If one tries to update it, it says 6.X is the newest:
user@desktop:~$ apt install llvm

llvm is already the newest version (1:6.0-41~exp5~ubuntu1).

Use 'sudo apt autoremove' to remove them.
0 upgraded, 0 newly installed, 0 to remove and 15 not upgraded.
I have also tried 1) using their apt deb sources (didn't work, nothing happens when added, latest version is still 6.X when using apt upgrade), and 2) downloading their files (no instructions given how to install).

I am on Mint 19.3, but this should also work for Ubuntu 18.04, which is what this Mint version is based on.
My solution was to specify the version to use specifically when installing:
The reason to use the glob asterisk here is that some of the related packages are also needed for things to work, so merely installing the base package will not work (at least, not for pyod which when you try pip install gives you
llvm-config: error: component libraries and shared library). This follow-up problem and solution was mentioned here.After this, you need to change the
llvm-configlink because otherwise it still points to the 6.X version. This is done by (from here):The config now points to the correct version. Installing the 10 version does not update this pointer. After this, my
pipcommand worked (i.e.pip install llvmlite, and after that,pip install pyod).
