An error occurred while installing ffi (1.9.10), and Bundler cannot continue.

If you’re seeing one or both of the following errors:

“ERROR: Error installing ffi: ERROR: Failed to build gem native extension.”

“An error occurred while installing ffi (1.9.10), and Bundler cannot continue.”

Check your `xcode-select`:

xcode-select -p

In my case, it was:

/Applications/Xcode-beta.app/Contents/Developer

But I had removed Xcode-beta and wanted to use the stable version of Xcode. Make the change:

sudo xcode-select -s /Applications/Xcode.app/Contents/Developer

And now `bundle install` should work. ðŸŽ‰
