Installation of SExtractor
I choose to install from source:
https://astromatic.github.io/sextractor/Installing.html
To run sh autogen.sh, install autoconf first:
apt install autoconf
To run ./configure:
sudo apt install libcfitsio-dev libatlas-base-dev libfftw3-dev libtool
After make, the compiled executable file will be at ./src/sex.
Install PSFex
Almost the same:

Install GalSim
https://psfex.readthedocs.io/en/latest/Installing.html
I did't compile GalSim. Install from conda env instead:
conda install -c conda-forge galsim
Usage
TBW
Just like PSFex XD
