DjangoをPostageSQLと使いたいと思い設定して､migrateしたのですが､以下のエラーが出てしまいました｡

**エラー:**

[/code]

psycopg2 が見つかないので pip を使ってインストールを試みたのですが､以下のエラーがでてできませんでした｡

**エラー:**

[code]

    Could not find any downloads that satisfy the requirement pycopg2
    No distributions at all found for pycopg2
    
[/code]

そこで､このエラーについて調べてのですが､ Unix の回答ばかりで Windows の回答が見つかりませんでした｡  
なので Windows での解決方法を教えていただけると幸いです｡

answer


Djangoのエラーでは `psycopg2` で、pip のエラーでは `pycopg2` となっています。  
PyPIには `pycopg`
というパッケージは登録されていないので、pipでのインストール時にパッケージ名を打ち間違えて、そのようなエラーが出ているのだと思います。

[code]

    pip install psycopg2
    
[/code]

で再度試してみて下さい。
