Install error on mac with skia-bindings

[arthursw]

I installed rust (curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh) and I have the following error when installing loopers (cargo install loopers) on mac OS Sonoma 14.7.2 (mac M1): Probing for Python 2 failed, please make sure that it's available in PATH

Full log:

error: failed to compile `loopers v0.2.0`, intermediate artifacts can be found at `/var/folders/75/4grlrb257sj3m6xnrtplj31r0000gv/T/cargo-installEbmwd6`.
To reuse those artifacts with a future compilation, set the environment variable `CARGO_TARGET_DIR` to that path.

Same error when I clone the repo and build it with git clone [email protected]:mwylde/loopers.git, cd loopers and cargo build.

You need to install Python 2 (not 3 which is the default) ... which is a problem now that v2 is end of life.

brew no longer installs python 2. You can do it by pyenv.

Suspect updating skia-bindings to a later version would be the the better choice (IIRC even with Python 2 installed it still fails on skia in some way.
