既にインストールされているscipyをインポートできません

Question

最近Python 2.7.11をインストールし、いくつかのパッケージをインストールしています。私はnumpyをインストールしましたが、scipyをインストールしようとしましたが、sudo pip install scipyを実行すると、次のエラーが表示されました。

したがって、問題なく実行されたsudo apt-get install python-scipyでインストールを進めました。しかし、私がPythonインタプリタに入り、scipyをインポートしようとすると、モジュールは存在しないと言います。どこで私は間違えましたか？私はまた、次のコードを試しました。

for p in sys.path: 
    if os.path.exists(os.path.join(p, 'numpy')): 
     print p 
     break 
else: 
    print "Numpy does not exist" 

"/usr/local/lib/python2.7/site-packages"となった。 scipyに同じコードを実行すると、「Scipyは存在しません」と表示されます。私はそれがパスの問題かもしれないと思います。どんな助けもありがとう。

Answer 1

私が欠けていたものは、scipyの依存関係でした。行方不明の図書館はlibatlas-base-devでした。私がそれをインストールしたら、問題なくインストールされたscipy。

時間を節約するために皆さんありがとうございます。そして、役に立つコメントのために@ knh170に特別な言及。私はそこに答えを見つけました。

Answer 2

Ubuntuでは、apt-get installがインストールされたPython 2.7パッケージが/usr/lib/python2.7/dist-packagesというフォルダに置かれます。したがって、Pythonのパスを更新する必要があります。

export PYTHONPATH="/usr/lib/python2.7/dist-packages:/usr/local/lib/python2.7/site-packages" 

また、あなたのpip install scipyはあなたのライブラリをインストールしていないので、/パッケージは、scipyのダウンロードに依存していませんでした。
