I tried to instal pyheif on mac m1 and i have this issue

You don't have homebrew properly installed in your system. Try this:

$ eval "$(/opt/homebrew/bin/brew shellenv)"

$ pip install git+https://github.com/carsales/pyheif.git@master#egg=pyheif
Collecting pyheif

I don't know how it was possible to install brew incorrectly. I also encountered the same problem, (I have a mac M2). If the problem is frequent, maybe make a note in the readmy.

[homm]

If the problem is frequent, it's better to fill a ticket in brew, since it's related to any other library, not pyheif only.

Have the same problem with mac m1 and python3.11

[homm]

@Headmaster11 Please provide more info:

1. Do you have HOMEBREW_PREFIX environment variable?
2. Did you do eval "$(brew shellenv)"?
3. Have you been aware that this is required step of brew installation?
4. Have you reed instruction during brew installation?
5. Have you filled a ticket in brew that you as a user had no idea about required installation step?

[laurogripa]

Same problem with Mac M2

I have $HOMEBREW_PREFIX set, tried eval, and installed all dependencies

[evanscho]

Same problem but with Mac Intel (Python 3.12), also have $HOMEBREW_PREFIX set, tried eval, and installed all dependencies. Ended up using Wand/Imagemagick.

Same problem here with mac m3 ☹️

Hey, sorry, could you please explain what I need the "HOMEBREW_PREFIX" variable for? I think I have it, but I don't know what to do next. Also, when typing the command in 2 nothing happens (I don't know what to write into the brackets). Ty for your help <3

[alew3]

yep, not working for me either .. using conda in my mac. I've set export HOMEBREW_PREFIX="/opt/homebrew" and mac m1 max

I get the following error after pip install

OSError: [Errno 66] Directory not empty: '/private/var/folders/rn/97_xyqmx1wx1bp6b9705k79m0000gn/T/pip-req-build-7zgp_3iw/.eggs/cffi-1.16.0-py3.11-macosx-11.0-arm64.egg/cffi-1.16.0.dist-info' -> '/private/var/folders/rn/97_xyqmx1wx1bp6b9705k79m0000gn/T/pip-req-build-7zgp_3iw/.eggs/cffi-1.16.0-py3.11-macosx-11.0-arm64.egg/EGG-INFO'
