anacondaqgisqgis-3
I am trying to install QGIS3 via Kyngchaos installer. But as I install python 3.6 in anaconda, the installer cannot find it. I know I can install a new environment or use symlinks to connected to Python that installed by homebrew as suggested in Installing QGIS3 on Mac? But as I have already installed a lot of packages in anaconda environment, I still hope to connect QGIS libs to it. Is it possible to do that?
Python 3.6 is installed in /Users/.../anaconda3/bin
Could you uninstall matplotlib and reinstall using the methods outlined at Kyngchaos?
This works well for me on Mavericks. Is there any particular reason you need to do things differently?
As noted by @dakcarto above, it appears that
The KyngChaos install does not support non-system Python installs; so, you will need to install
matplotlibin system Python's site-packages. The best means is to use KyngChaos's installer.
I use both Macos Kyngchaos QGIS and Anaconda Python on my Mac with success.
To do this, you must set your Anaconda Python path in your QGIS variables environment.
Go to QGIS > Preferences > System
In the environment Set PYTHONPATH as a new variable and add /Applications/anaconda2/bin as a value. Set it to overwrite. Restart QGIS, you'll see the new PYTHONPATH variable loaded in the read only section above.
In Anaconda, what I did, you can even create a QGIS specific Python environment with all the necessary libraries inside. You won't need at all to add it to your Macos system paths, unless you are needing it for other applications. But in QGIS you'll have to input /Applications/anaconda2/envs/QGIS/bin instead, as the PYTHONPATH variable.
Then, when you install a new QGIS extension, if a python library is missing for this extension to work properly, just add it to your QGIS Anaconda installation. You won't get any errors anymore.

I would like to share my experiment though I still failed to install it.
It seems in my case that The python path should be
/Library/Frameworks/Python.framework/Versions/3.6/bin. I try to create a symlink likeln -s /anaconda3/bin /Library/Frameworks/Python.framework/Versions/3.6/binand then I can 'successfully' install QGIS3.However when I open QGIS3 that I have installed. It crushed suddenly when loading the software without any dialog box showing any errors or warnings.
I am still wondering whether there are some libraries that I should install besides GDAL and what's the reason for its crush.
