mecabをインストール後、libmemcab.so.1でerrorがでた場合の対処方法 - ドラあり！*ドラゴンに挑むアリの物語 ** Python使いの日々

mecabをインストール後、libmemcab.so.1でerrorがでた場合の対処方法について書きます。

# mecab
mecab: error while loading shared libraries: libmecab.so.1: cannot open shared object file: No such file or directory

と出ます。ふむふむ、ldconfigで共有ライブラリを認識させます。

ldconfig :共有ライブラリを認識させる

プログラムをインストール後に実行した時、使用例に示すようなエラーをおこすことがあります。
これは、必要なライブラリがシステムに認識されていない為に発生します。

共有ライブラリを認識させます。

# ldconfig

これで認識完了です。

このあとは辞書をインストールしていきます。

ipadicのインストール

ではmecabをコマンドで実施してみます。

mecab
tagger.cpp(151) [load_dictionary_resource(param)] param.cpp(71) [ifs] no such file or directory: /usr/local/lib/mecab/dic/ipadic/dicrc

ipadicのインストール

ipadicがないとでるので、インストールしてみましょう。
