# On macOS, system python binaries like /usr/bin/python and $(xcrun -f python3)
|
|
# are shims. They do some light validation work and then spawn the "real" python
|
|
# binary. Find the "real" python by asking dyld -- sys.executable reports the
|
|
# wrong thing more often than not. This is also useful when we're running under
|
|
# a Homebrew python3 binary, which also appears to be some kind of shim.
