原来的版本为2.4,因在安装scons会报关于Python的模块问题
所以就在SUSE Linux下进行升级到2.6
若想要使用rpm -e命令删除python的话是无法删除的,因为软件的依赖性。
所以使用源代码包进行安装升级
下载2.6.8的版本
http://www.python.org/download/releases/2.6.8/
创建安装目录 mkdir /usr/local/python2.6
进行编译安装 ./configure –prefix=/usr/local/python2.6 make&make install
创建连接
mv /usr/bin/python /usr/bin/python_bak (保存原来的版本)
ln -s /usr/local/python2.6/bin/python /usr/bin
测试结果
万事没有那么顺风顺水。。。
报错了。。。
ImportError: No module named readline
谷歌之~貌似缺少readline模块
2 安装 readline
装 readline 之前,需要先安装 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
出现”
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
” 表示安装成功
然后,安装 readline-devel ,从SuSe系统自带的DVD光盘拷贝对应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
装完这两个依赖包,就可以开始安装 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”,不然会报错:”libreadline.a: could not read symbols: Bad value”)
make CFLAGS=-fPIC
make CFLAGS=-fPIC install
3. 安装 python 的 readline 模块
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
出现”
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
” 表示安装成功
然后再敲python就不会出现”ImportError: No module named readline”的提示了
