No such file or directory: 'llvm-config'

Hello,

I am trying to install llvmlite on MacOS Catalina for Python 3.8. I firstly used the pyCharm IDE it did not worked. I installed llvm and run pip3 install llvmlite

I am receiving an error message which says:

ERROR: Command errored out with exit status 1:

The config file exists and it is in this location: /usr/local/Cellar/llvm/9.0.0_1/include/llvm/config

I don’t know what am I doing wrong. I tried to reinstall llvm and link it. brew reinstall llvm brev link llvm

in that case, I receive another error:

`Warning: Refusing to link macOS-provided software: llvm
If you need to have llvm first in your PATH run:
  echo 'export PATH="/usr/local/opt/llvm/bin:$PATH"' >> ~/.bash_profile

For compilers to find llvm you may need to set:
  export LDFLAGS="-L/usr/local/opt/llvm/lib"
  export CPPFLAGS="-I/usr/local/opt/llvm/include"`

I also tried to use this: $ sudo LLVM_CONFIG=/usr/local/Cellar/llvm/9.0.0_1/include/llvm/config/llvm-config.h pip3 install llvmlite

New error is:

Can you please help me to understand what is the problem here?

If the error appeared after April the 17th (see history) try installing it with

pip3 install llvmlite==0.31.0

If your goal is to use Numba, you will have to wait until our late-December release. Python 3.8 changed bytecode generation significantly enough to break the Numba frontend, and we are working on fixing it. The first patches have been merged to Numba’s master branch, but there are still pending Python 3.8 fixes.

If you use Python 3.7, you won’t have any build issues as we have posted binary wheels and conda packages for all platforms.
