前文: 解決策を調べてみましたが、何も効果がありませんでした。
まず、次のコマンドを実行すると
$ sudo python --version
Python 2.7.5+
Python2と3でも同様
$ sudo python2 --version
Python 2.7.5+
$ sudo python3 --version
Python 2.7.5+
私も全く同じものを受け取ります
例えばFirefoxをインストールしようとすると
sudo apt-get install firefox
この人が抱えている問題は理解できる
まず、この解決策は私にはうまくいきませんでした。むしろ、あなたが指定した方法でこの人が何を言っているのか、私にはよくわかりません。
2、python3を再インストールできない
アップデート
ソースから python 3.4.3 を再インストールしましたが、python3 のバージョンを確認すると、まだ python 2.7.5+ が表示されます。
