Many exotic errors while installing a package are solved by just upgrading `pip` first.

/// tip

You would normally do this **once**, right after you create the virtual environment.

///

Make sure the virtual environment is active (with the command above) and then run:

<div class="termy">

```console
$ python -m pip install --upgrade pip

If an object meets replication rules as set in the replication configuration, `X-Amz-Replication-Status` is first set to `PENDING` as the PUT operation completes and replication is queued (unless synchronous replication is in place). After replication is performed, the metadata on the source object version changes to `COMPLETED` or `FAILED` depending on whether replication succeeded. The object version on the target shows `X-Amz-Replication-Status` of `REPLICA`
