Fix Python Dependencies(mac only)

brew install gnu-sed

Chmod 755

cd pythonscript/osx-64-cpython/
chmod 755 ./bin/*
chmod 755 ./lib/libpython3.6m.dylib

Change Python shebang

cd pythonscript/osx-64-cpython/
find ./bin/ -type f -not -name 'python3' -not -name 'python3.6' -not -name 'python3.6m' | xargs gsed -i '1c #!/usr/bin/awk BEGIN{a=ARGV[1];b="";for(i=1;i<ARGC;i++){b=b"\t"ARGV[i];}sub(/[a-z_.\-]+$/,"python3.6",a);system(a""b)}'

Add LC_RPATH and fix LC_LOAD_DYLIB for python

cd pythonscript/osx-64-cpython/

install_name_tool -add_rpath @loader_path/../lib/ ./bin/python3
install_name_tool -add_rpath @loader_path/../lib/ ./bin/python3.6
install_name_tool -add_rpath @loader_path/../lib/ ./bin/python3.6m

otool -L ./bin/python3 | grep -e libpython3.6m | cut -d ' ' -f 1 | xargs -I{} sh -c 'install_name_tool -change {} @rpath/libpython3.6m.dylib ./bin/python3'
otool -L ./bin/python3.6 | grep -e libpython3.6m | cut -d ' ' -f 1 | xargs -I{} sh -c 'install_name_tool -change {} @rpath/libpython3.6m.dylib ./bin/python3.6'
otool -L ./bin/python3.6m | grep -e libpython3.6m | cut -d ' ' -f 1 | xargs -I{} sh -c 'install_name_tool -change {} @rpath/libpython3.6m.dylib ./bin/python3.6m'

install_name_tool -id @rpath/libpython3.6m.dylib ./lib/libpython3.6m.dylib
install_name_tool -add_rpath @loader_path/ ./lib/libpython3.6m.dylib

Now you can use pip!

Add LC_RPATH and fix LC_LOAD_DYLIB for libpythonscript

cd pythonscript/osx-64-cpython/

install_name_tool -id @rpath/libpythonscript.dylib ./libpythonscript.dylib

install_name_tool -add_rpath @loader_path/ ./libpythonscript.dylib
install_name_tool -add_rpath @loader_path/lib/ ./libpythonscript.dylib // for Editor

otool -L ./libpythonscript.dylib | grep -e libpython3.6m | cut -d ' ' -f 1 | xargs -I{} sh -c 'install_name_tool -change {} @rpath/libpython3.6m.dylib ./libpythonscript.dylib'

Using pip

Easy Access

cd pythonscript/osx-64-cpython/
./bin/pip3 --version

freeze and install

cd pythonscript/osx-64-cpython/
./bin/pip3 freeze > ../../../requirements.txt
./bin/pip3 install -r ../../../requirements.txt
