## Install FastAPI

The first step is to install FastAPI.

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and then **install FastAPI**:

<div class="termy">

```console
$ pip install "fastapi[standard]"

---> 100%
```

                        rr.getPolicy(true).getUpdatePolicy(),
                        rr.getPolicy(false).getChecksumPolicy());

            } catch (Exception e) {
                throw new RuntimeException("Unable to create repository", e);
            }
        } else {
            // TODO
            throw new UnsupportedOperationException("Not yet implemented");
        }
    }

            pass  # pragma: no cover
    assert e.value.code == status.WS_1000_NORMAL_CLOSURE
