Dear Matthew,

I thank you very much for your quick reply as well as this of Carlo Segre. I apologize, I did not look at the archived messages and now it is clear.
I will try to install Larch as you said and keep you in touch if I have any trouble or success !

Bests,

Laurent

Hi Laurent, 

Hopefully, you saw the earlier replies - if not, see the archived messages at https://millenia.cars.aps.anl.gov/pipermail/ifeffit/2022-November/thread.html

The basic answer is that you do not need to use Anaconda to run Larch on macOS.   There is a MacPorts port available, for example.  In fact, Larch is distributed with PyPI so you should (or at least "may") be able to install it in any Python environment, provided the dependencies are also available. 

I also agree with Dr. Kumar's response that installing into a system-provided Python may not be the best idea (on any system, but especially macOS).   Python does support virtual environments pretty well, which I would highly recommend to anyone wanting to install using a system-provided Python.

If you have tried installing Larch and run into trouble, let us know what you tried and what did not work.

Dear Mr or Mrs,

I sent you this message about ten days ago but on my side I did not receive any answer.
I would like to avoid installing Anaconda during the installation of Larch on my MacOS computer. I would like to know if it is possible or not.

I thank you in advance for your help.

Best regards,

Objet: Installing Larch without installing Anaconda

Dear Mr or Mrs,

I am Laurent Tranchant, post-doctoral researcher working at the IPANEMA laboratory at the SOLEIL synchrotron in France.
I would like to install Larch (especially to use XAS Viewer to treat my XAS data) without installing Anaconda on MacOS. Do you know if it is possible or not ? For example by using MacPorts instead of Anaconda...
It seems that all the solutions proposed online to install Larch on MacOS require the installation of Anaconda Python environment.

I thank you in advance for your help.

Best regards,

Laurent Tranchant
