llvmlite: 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:
