pip is not a supported installation method for Anaconda - you have to go through something like Miniconda or a full Anaconda distribution.

install llvmlite and numba library for python2 on jetson xavier nx

I want to install numba and llvmlite for python2 on jetson. However there seems to be no documentation on the same. Everything is for python3. I am trying to run a program on ros melodic and hence need the libraries in python2.
When i try
python2.7 -m pip install numba==0.45
I am getting following error

I solved it.
What worked for me was
sudo apt-get install python-numba

Try to upgrade pip and install the latest versions that support Python 2.7:
python2.7 -m pip install -U "pip < 21.0"
python2.7 -m pip install "llvmlite < 0.32.1" "numba < 0.46"

You probably saw this, but just in case : https://guidedlda.readthedocs.io/en/latest/
If pip install doesn’t work then try the next step.

to the PKG_CONFIG_PATH environment variable

what should i do ?

UPDATED ANSWER
It's PyGObject that is failing
try
sudo yum install gcc gobject-introspection-devel cairo-devel pkg-config python3-devel gtk3 cairo-gobject-devel
export PKG_CONFIG_PATH=/usr/lib64/pkgconfig
before attempting the pip install
This actually worked for me on Centos7
