Happened the same, even with sudo curl fails.

I think we need to update the install script to "just" install it on user's "~/.bin".

When we really want to install it on /usr/local/bin it should be:

curl -fsSL https://func-e.io/install.sh | sudo bash -s -- -b /usr/local/bin

Note I think we need to update the docs on a newer macOS device (M1, M2, Mx). Since brew is not installed on /usr/local anymore (but /opt/homebrew) the permission is still wrong.

Or we can install it in the current working directory:

curl -fsSL https://func-e.io/install.sh | bash

Or via homebrew:

brew install func-e

curl https://func-e.io/install.sh | sudo bash -s -- -b /usr/local/bin worked for me

Thanks @dio for the comprehensive solution.

I'd vote for just updating the func-e homepage to include these additional installation instructions, and also mention that can be installed using brew.

brew install func-e
