# SIFR-BUILD-0901: Standalone install receipt is missing or outside the self-update install rules.

> Standalone install receipt is missing or outside the self-update install rules.

`SIFR-BUILD-0901` belongs to the **Build pipeline** diagnostic family. It means: standalone install receipt is missing or outside the self-update install rules.

## Why It Happens

Sifr reached the build pipeline but could not create, run, or verify one of the generated build artifacts.

<Info>
  Use `sifr --explain SIFR-BUILD-0901` locally to see the renderer's exact message template and any machine-applicable suggestions for the compiler version you are running.

## Erroneous Code

```bash theme={null}
sifr build app.sifr --output /root/out
```

## How To Fix It

Check the generated build path, Cargo/rustc output, and whether Sifr can create its temporary workspace and final artifact.

## Fixed Code

```bash theme={null}
sifr build app.sifr --output build
```
