installing modules from within a script

Recommended Posts

approachVectorWorks : v2020

MacOSX        : 10.14.6

 

Hello

 

I have used until now sucessfully the following code snippet to install missing modules:

 

see also this forum entry:  "PIL python image library for vw 2018"

 


vModule = 'mymoduleToimport'

pip.main(['install', '--upgrade', '-v', vModule])

# or 

vVW_AppUserPy_folder = '/Users/myuser/Library/Application\ Support/VectorWorks/2020/PythonExternals'

pip.main(['install', '--upgrade', '-v', vModule, '--target', vVW_AppUserPy_folder])

This works for most modules.  For some modules (e.g. pyspatial) this approach is not working and instead a second instance of the VectorWorks.app is started without any error (only verbose console output), but those modules are finally not installed. As far as I can see, those modules that are not working are calling the setup.py script. Is there any way to suppress this behavior?

 

While "debugging" I learned, that in PIP > version 10 (actual PIP version is version 20, and in VectorWorks v2020 version 8.1 is installed by default), the pip.main() function is removed and the following construct should be used:

 

vPip_proc = subprocess.run([sys.executable, '-m', 'pip', 'install', '--upgrade', '-v', vModule, '--target', vVW_AppUserPy_folder ])

vPip_proc_exit_code = vPip_proc.returncode
vPip_proc_sdtout = vPip_proc.stdout
vPip_proc_sdterr = vPip_proc.stderr

 

Unfortunately this approach is not working at all for all python modules. Every time a second instance of the VectorWorks.app is started without any error and output and no module is installed.

 

I would appreciate any hint or suggestion how to solve this problem. Many thanks in advance,

Hello

 

in the following there is the VW log output of installing the module "pyspatial" (the same with "rtree") that does not work with the pip.main() approach and starts a setup.py "process" and a second instance of the VectorWorks.app:

P.S. the Marionette.VerifyOrGetLib() approach does not work really, if you do want to install libs/modules in more generalistic way like this e.g. "pip.main(install --upgrade 'dateutil>=2.5.0' and without passing the ressource URL as it is needed in Marionette.VerifyOrGetLib()

Hello

 

I have posted some (final) findings on the other  topic pil-python-image-library-for-vw-2018.

 

As for the problem with the before mentioned "pyspatial" module the problem is inherent to the actual version of the "pyspatial" module and the pip version that module is installed with. Other modules that use setup.py "e.g. rtree" can be installed with above (final) findings without any problems.
