I am able to get this to work.
I had to invoke parent's run before my post install logic could kick.

Subject: "Post install setup does not work as expected with pip install"
Hello,
I have a post install class that looks like this:
if('darwin' in sys.platform):
class PostInstall(install):
""" Post installation - run install_name_tool on Darwin """
def run(self):
clipath = os.getenv('IBM_DB_HOME', '@loader_path/clidriver')
print("in PostInstall with {}".format(clipath))
for so in glob.glob(r'build/lib*/ibm_db*.so'):
os.system("install_name_tool -change libdb2.dylib
{}/lib/libdb2.dylib {}".format(clipath, so))
install.run(self)
cmd_class = dict(install = PostInstall)
And I pass cmd_class to setup(..) as:
setup(..
include_package_data = True,
cmdclass = cmd_class,
**extra
)
When I execute setup.py as "python setup.py install", then the PostInstall
operation is executed after the ibm_db.so is built and installed and I see the
intended result.
Howeever, when I run "pip install ibm_db" or "pip install .",
the execution order looks like this:
warnings.warn(notifyString)
running install
in PostInstall with /Applications/dsdriver/ ==> this is my post install
script
running build
running build_py
creating build
creating build/lib.macosx-10.9-x86_64-3.7 ==> I need to traverse to this
folder to find my shared library
I would expect it to be run post the ibm_db is installed, not before it gets
built.
Can you please let me know how can this be fixed. Is this a bug with pip?
