I created a sage project and ran `yarn build` it fails with this error.

```
yarn run v1.22.19
$ bud dev
/bin/sh: bud: command not found
error Command failed with exit code 127.
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.
```

Is there any workaround to this issue?

Hey,

Run:

```
yarn dev
```

I think you need to install it first.

I ran `yarn` first but I had no luck. I have the most recent version installed, and my node and npm are current. With older theme installations, though, this is not the case.

For example, when I first ran `yarn dev` in an existing theme, everything seemed fine—until, I deleted the node modules folder and ran yarn once more.

For anyone having the same issue, please run `npm cache clean --force` and it will fix the issue!

If `npm cache clean --force` doesn’t work, try adding bud to your yarn.lock by running `yarn add @roots/bud --dev` as per the [bud documentation](https://bud.js.org/guides/getting-started/).

For me `yarn cache clean` seemed to work. (since I am using yarn & volta)
