Python2.6→2.7へアップデートするにあたってやったこと

Last updated at Posted at 2014-05-16

はてなにメモってた過去記事を再掲シリーズ(ちょっと古いかもしれない)

インストールに必要なものをインストール

$ sudo yum install zlib zlib-devel tk-devel tcl-devel sqlite-devel ncurses-devel gdbm-devel readline-devel bzip2-devel db4-devel openssl-devel

Pythonをダウンロードして解凍する

$ wget http://python.org/ftp/python/2.7.2/Python-2.7.2.tgz
$ tar zxvf Python-2.7.2.tgz

インストール

$ cd Python-2.7.2
$ ./configure --with-threads --enable-shared

エラー対策(x86_64の場合)ここで,実行すると

python: error while loading shared libraries: libpython2.7.so.1.0: cannot open shared object file: No such file or directory

とエラーで動かない.コンパイルはされているので,シンボリックを貼る.

$ ln -s /usr/local/lib/libpython2.7.so.1.0 /lib64/

@CentOS

Python2.7のinstall

http://wasure-memo.h-tsk.com/2012/03/centos-62-python-272.html
http://memo.yomukaku.net/entries/jbRkQkq

wget http://python.org/ftp/python/2.7.2/Python-2.7.2.tgztar zxvf Python-2.7.2.tgz
sudo yum install zlib zlib-devel tk-devel tcl-devel sqlite-devel ncurses-devel gdbm-devel readline-devel bzip2-devel db4-devel openssl-devel
cd Python-2.7.2
./configure --with-threads --enable-shared
make
sudo make install
python2.7

pipのinstall

wget http://peak.telecommunity.com/dist/ez_setup.py
sudo /usr/local/bin/easy_install-2.7 pip

$ sudo /usr/local/bin/pip-2.7 install jubatus

$ sudo /usr/local/bin/pip-2.7 install MySQL-python

エラー1:ここでmysql_configがないって怒られた

$ sudo yum install MySQL-devel.x86_64
$ which mysql_config

エラー2:インストールできない

解決策

(無理矢理だけど)

$ sudo cp -rp /usr/lib64/python2.6/site-packages/_mysql* /usr/local/lib/python2.7/site-packages
$ sudo cp -rp /usr/lib64/python2.6/site-packages/MySQL* /usr/local/lib/python2.7/site-packages

一応できた…

ちなみにエラー2のエラーログは
