I've been using bvm to manage my bit versions for a while now, but now suddenly i'm getting bvm: command not found.
bit -v still gives me the correct output, so bit is still installed...
Tried running where bvm to find the binary but then i just get not found as well.
OK, it turns out this is a general issue with updating node version and global packages.
Global packages are apparently linked to a specific version of node, presumably to ensure compatibility, so when you update node version you need to re-install any global packages.
So just run
npm i -g @teambit/bvm(or yarn/pnpm equivalent, however you originally installed bvm) to re-install bvm and then all will be good.
