原來的版本為2.4，因在安裝scons會報關於python的模塊問題
所以就在SUSE Linux下進行升級到2.6
若想要使用rpm -e命令刪除python的話是無法刪除的，因為軟件的依賴性。
所以使用源代碼包進行安裝升級
下載2.6.8的版本
http://www.python.org/download/releases/2.6.8/
創建安裝目錄 mkdir /usr/local/python2.6
進行編譯安裝 ./configure --prefix=/usr/local/python2.6 make&make install
創建連接
mv /usr/bin/python /usr/bin/python_bak （保存原來的版本）
ln -s /usr/local/python2.6/bin/python /usr/bin
測試結果
萬事沒有那麼順風順水。。。
報錯了。。。
ImportError: No module named readline
谷歌之~貌似缺少readline模塊
2 安裝 readline
裝 readline 之前,需要先安裝 setuptools
cd /usr/src/
wget http://pypi.python.org/packages/source/s/setuptools/setuptools-0.6c11.tar.gz#md5=7df2a529a074f613b509fb44feefe74e
tar zxvf setuptools-0.6c11.tar.gz
cd setuptools-0.6c11/
python setup.py install
出現"
Installed /usr/local/lib/python2.7/site-packages/setuptools-0.6c11-py2.7.egg
Processing dependencies for setuptools==0.6c11
Finished processing dependencies for setuptools==0.6c11
" 表示安裝成功
然後,安裝 readline-devel ,從SuSe系統自帶的DVD光盤拷貝對應rpm包.
rpm -ivh readline-devel-5.1-24.13.x86_64.rpm
rpm -ivh readline-devel-32bit-5.1-24.13.x86_64.rpm
裝完這兩個依賴包,就可以開始安裝 readline 了
cd /usr/src/
wget ftp://ftp.cwru.edu/pub/bash/readline-5.2.tar.gz
tar zxvf readline-5.2.tar.gz
cd readline-5.2/
CFLAGS="-O3 -fPIC" ./configure
(一定要加"-O3 -fPIC",不然會報錯:"libreadline.a: could not read symbols: Bad value")
make CFLAGS=-fPIC
make CFLAGS=-fPIC install
3. 安裝 python 的 readline 模塊
cd /usr/src/
wget http://ipython.scipy.org/dist/readline-2.5.1.tar.gz
tar zxvf readline-2.5.1.tar.gz
cd /usr/src/readline-2.5.1
cp /usr/local/lib/{libreadline.a,libhistory.a} readline/
python setup.py install
出現"
Installed /usr/local/lib/python2.7/site-packages/readline-2.5.1-py2.7-linux-x86_64.egg
Processing dependencies for readline==2.5.1
Finished processing dependencies for readline==2.5.1
" 表示安裝成功
然後再敲python就不會出現"ImportError: No module named readline"的提示了
[[email protected] readline-2.5.1]# python
