Upgrade Python2.4 to 2.6 in SUSE Linux

The original version is 2.4. The python module is reported when scons is installed.

So in SUSE Linux, upgrade to 2.6.

If you want to use the rpm-e command to delete python, You cannot delete it because of software dependency.

So use the source code package for installation and upgrade

Download 2.6.8

Http://www.python.org/download/releases/2.6.8/

Create the installation directory mkdir/usr/local/python2.6

Compile and install./configure -- prefix =/usr/local/python2.6 make & make install

Create a connection

Mv/usr/bin/python/usr/bin/python_bak (Save the original version)

Ln-s/usr/local/python2.6/bin/python/usr/bin

Test Results

Nothing goes smoothly...

Error...

ImportError: No module named readline

 

Google ~ It seems that the readline module is missing

 

2. Install readline

Before installing readline, install 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

"

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

"Indicates that the installation is successful.

Then, install readline-devel and copy the corresponding rpm package from the DVD disc that comes with the SuSe system.

Rpm-ivh readline-devel-5.1-24.13.x86_64.rpm

Rpm-ivh readline-devel-32bit-5.1-24.13.x86_64.rpm

After installing these two dependent packages, you can start to install readline.

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

(You must add "-O3-fPIC". Otherwise, the error "libreadline. a: cocould not read symbols: Bad value" will be reported ")

Make CFLAGS =-fPIC

Make CFLAGS =-fPIC install

3. Install the python readline Module

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

"

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

"Indicates that the installation is successful.

Then, when you press python, the prompt "ImportError: No module named readline" will not appear.
