巨大なPythonの問題

巨大なPythonの問題

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

Python3をアンインストールして2.7だけを使いたい

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。
