Getting legacy-install-failure when trying to install insiders

[zerenxyz]

I have insiders installed on a project and it works fine, however when installing it on a new project I get this error after running the pip install command from the docs

Running the same install and upgrade command for insiders on the previous project works just fine, so im lost

It looks like you need to install libxml2, which is necessary for lxml. It should be pre-installed on most systems. I'd just do what it says, i.e., execute xcode-select --install, which you need anyway to develop on a Mac. However, I'm not sure why it works on the same machine on another project.
