Laravel Valet | Uninstalled Valet, Installed Valet 2.0 Unable to determine linked PHP.

Ok, Adam W. helped me get past this problem with this:

rm -rf ~/.composer/vendor

composer global update

valet install

But now I'm having an issue with OSX crashing and restarting when I run Valet Install and it gets to restarting dnsmasq

Anyone seen a similar issue, have any suggestions.

Run brew doctor and make sure you are actually using the brew installed php (php71). Sometimes you may have to restart your brew services as well.

Hey, thanks for the fast reply, hoping to get this resolved, I'm on the verge of doing a reinstall of OSX.

Here's what brew doctor is telling me:

Warning: A newer Command Line Tools release is available. Update them from Software Update in the App Store.

Warning: "config" scripts exist outside your system or Homebrew directories. ./configure scripts often look for *-config scripts to determine if software packages are installed, and what additional flags to use when compiling and linking.

Having additional scripts in your path can confuse software installed via Homebrew if the config script overrides a system or Homebrew provided script of the same name.

Thanks to ejdelmonico for following up on me with this. Running an update on OSX and brew cleanup resolved this last issue for me valet 2 is up and running.
