this post is for those who’re following this guide: https://roots.io/getting-started/docs/windows-basic-setup/
In case you’re getting Composer error at TASK [wordpress-install : Install Dependencies with Composer] ****************** like this:
Plugin installation failed, rolling back
then try this workaround:
at your /roots-example-project.com/site/composer.json
run composer update
try vagrant up again
I spent 3 days on this issue, I was so angry that my previous post got unlisted by admins lol.
