djangoとpostgreSQLでpsycopg2のエラーメッセージをデバッグできません

Question

psycopg2を使用してdjango Webアプリケーションに接続されたpostgreSQLデータベースを作成しようとしています。私はpython manage.py migrate

(temp-python) ❯ python manage.py migrate

を実行したときに私はアーチのlinuxを実行していることだし、本当に、どこにこのエラーをデバッグで開始するすべての助けを事前に感謝を知らない、次のエラーが供給しています。

Answer 1

psycopg2 versions prior to 2.2には既知のバグがありました。

これには、restarting it, as it may be a runtime problemのいずれかのオプションがあります。または、--no-binary psycopg2コマンドを使用して再インストールすることもできます。これにより、そのスレッドの最後のコメントごとにホイールを使用できなくなります。
