It is recommended to start using Mops to manage the `moc` version - [Toolchain Management with Mops | Mops Docs](https://docs.mops.one/cli/toolchain)

Mops supports per-project moc version management instead of global moc version.

Eventually `mocv` will be deprecated.

To uninstall mocv:

```raw
mocv reset
npm uninstall -g mocv

```
