Installation issue

[LydiaMak]

Hi,

I am working on an osx-arm64 which gives me the error that the 3.7 do not exist. Can I use a different python when creating the environment? Will this give me other issues?

Cheers,

Lydia

I have created the environment with python 3.8 and then I activated and tried to install but I get

I had the same problem - albeit on a mac with an intel chip.

I got around it by downloading the repo as a zip file. I then extracted this and navigated into the folder. Then I ran this whilst my conda env was activated:

python setup.py bdist_wheel

Then when the wheel file is built (it ends up in a folder called dist/) you just run:

pip install dist/<wheelfile-name>

Hi @GabrielF98

Thank you for your advice. I get the following error doing this

Are you using python 3.8 as well?

[GabrielF98]

Hi @LydiaMak I am using python 3.7 in a new conda environment as suggested in the install docs for autophot.

I'm not exactly sure what is causing your error but you may be missing a package, you should check that the 'markupsafe' python package is installed. This command will check if it is installed and install the package if it is not installed.

pip install MarkupSafe

Is there a way to install this without conda?

[tkillestein]

I managed to get this working on my M2 Mac, using the steps below:

conda create -n autophot_env
conda activate autophot_env
conda config --env --set subdir osx-64
conda install python=3.7
conda install -c astro-sean autophot

although given autophot is being rewritten, not sure for how much longer this'll be needed :)
