私のDebian-JessieコンピュータにGNS3（ネットワークエミュレータ）をインストールしましたが、プログラムを起動しようとすると、次のエラーが表示されます。
Could not find platform independent libraries <prefix>
Could not find platform dependent libraries <exec_prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
Fatal Python error: Py_Initialize: Unable to get the locale encoding
ImportError: No module named 'encodings'
Aborted
なぜこれが起こるのかご存知ですか？
役に立つかと追跡もしてみました。

また、次のようにPYTHONHOMEを設定しようとしましたが、まだ運がありません。
user@station:~$which python
/usr/bin/python
user@station:~$export PYTHONHOME=/usr/bin
user@station:~$echo $PYTHONHOME
/usr/bin
user@station:~$gns3
Fatal Python error: Py_Initialize: Unable to get the locale encoding
ImportError: No module named 'encodings'

答え1
努力するexport PYTHONHOME=/usr/bin。 PythonはDebianにインストールされている必要があります/usr/bin。
それ以外の場合は、which python返されるディレクトリを実行して使用します。export PYTHONHOME=<directory>
編集する
それも試してみてくださいexport PYTHONPATH=/usr/lib/python2.7。
これを行う前に、ディレクトリが実際に存在することを確認してください。 Pythonのバージョンによって異なりますが、モジュールが保存される場所である必要があります。
より良い方法は、次に置き換える代わりに追加することです。
export PYTHONPATH=$PYTHONPATH:/usr/lib/python2.7
答え2
今日も同じ問題が発生しました。まだ解決策が見つかりませんでしたが、どのように解決したかをお知らせします。
まず、ディストリビューションに従って gns3 インストールをクリーンアップします。私はDebianを使用しているので、次のコマンドを使用しました：$ sudo apt-get autoremove --purge gns3 *
2. gns3公式ウェブサイトにアクセスしてください：https://docs.gns3.com/1QXVIihk7dsOL7Xr7Bmz4zRzTsJ02wklfImGuHwTlaA4/新しいgns3バージョンのインストールに従ってください。
