# `Beancount.Query.NotInstalledError`
[🔗](https://github.com/thanos/beancount_ex/blob/v0.6.0/lib/beancount/query.ex#L19)

Raised when the configured `bean-query` executable cannot be located.

This signals an environment/setup problem, distinct from a query that fails
(which is returned as `{:error, %Beancount.Result{}}`).
