Cargo Install Python Feature Fail

[dan-fritchman]

Great library, thanks for your work on it!
My attempts to install the python feature via cargo install have failed like so:

$ cargo install typeshare-cli --features python
    Updating crates.io index
  Installing typeshare-cli v1.13.2
error: failed to compile `typeshare-cli v1.13.2`, intermediate artifacts can be found at `/var/folders/2t/c78725w17pb1bcxb9t3k17wc0000gn/T/cargo-installqmqDAA`.
To reuse those artifacts with a future compilation, set the environment variable `CARGO_TARGET_DIR` to that path.

Caused by:
  the package 'typeshare-cli' does not contain this feature: python

The content of that intermediate artifact has a bunch of system info. It's running on a recent-vintage Mac, rust v1.86.

    }
  },

}

I know Python support is provisional.
Where does/ should it work best? (Thinking on other platforms/ OSes, on the git top-of-tree, etc.)

Thanks!

Hi,

We'll have a new release for typeshare-cli shortly. The current version 1.13.2 does not have the python feature.
