"Python applications will often use packages and modules that don't come as "
"part of the standard library.  Applications will sometimes need a specific "
"version of a library, because the application may require that a particular "
"bug has been fixed or the application may be written using an obsolete "
"version of the library's interface."
msgstr ""
"Python アプリケーションは、標準ライブラリに含まれないパッケージやモジュールを"
"よく使います。特定のバグの修正が必要だったり、古いバージョンのライブラリのイ"
"ンターフェイスに依存していたりするため、ライブラリの特定のバージョンが必要に"
"なることもあります。"

msgid ""
"This means it may not be possible for one Python installation to meet the "
"requirements of every application.  If application A needs version 1.0 of a "
"particular module but application B needs version 2.0, then the requirements "
"are in conflict and installing either version 1.0 or 2.0 will leave one "
"application unable to run."
msgstr ""
"このため、1つの Python 環境ですべてのアプリケーションの要求を満たせるとは限り"
"ません。アプリケーション A があるモジュールのバージョン 1.0 を必要とし、アプ"
"リケーション B がバージョン 2.0 を必要とする場合、両者の要求は衝突します。"
"1.0 と 2.0 のどちらをインストールしても、片方のアプリケーションは動作しませ"
"ん。"

msgid ""
"The solution for this problem is to create a :term:`virtual environment`, a "
"self-contained directory tree that contains a Python installation for a "
"particular version of Python, plus a number of additional packages."
msgstr ""
"この問題は :term:`仮想環境 <virtual environment>` を作ることで解決できます。"
"仮想環境とは、特定のバージョンの Python といくつかの追加パッケージを含む自己"
"完結したディレクトリ構造です。"

msgid ""
"Different applications can then use different virtual environments. To "
"resolve the earlier example of conflicting requirements, application A can "
"have its own virtual environment with version 1.0 installed while "
"application B has another virtual environment with version 2.0. If "
"application B requires a library be upgraded to version 3.0, this will not "
"affect application A's environment."
msgstr ""
"アプリケーションごとに異なる仮想環境を使うことができます。先ほどの例では、ア"
"プリケーション A 専用の仮想環境にバージョン 1.0 をインストールし、アプリケー"
"ション B 用の仮想環境にバージョン 2.0 をインストールすれば要求の衝突を解決で"
"きます。アプリケーション B のためにライブラリをバージョン 3.0 に更新する必要"
"があっても、アプリケーション A の環境には影響しません。"

"A common directory location for a virtual environment is ``.venv``. This "
"name keeps the directory typically hidden in your shell and thus out of the "
