• GodotPyton 0.11.3

Build Environments

Installing Godot

In Mac

brew cask install godot

In Windows

scoop bucket add extras
scoop install godot

Installing Godot Python

1. Import Project
2. Search Python in AssetLib
3. Install PythonScript for your environment
4. Reboot Editor

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
