Ubuntu 11.04 x64 下安装Python

在网上搜了下，找到了如下安装顺序：

 

Install python2.7
wget http://www.python.org/ftp/python/2.7/Python-2.7.tar.bz2
tar xjf Python-2.7.tar.bz2
cd Python-2.7/
./configure
make
sudo make altinstall

Install setuptools
cd ..
wget http://pypi.python.org/packages/source/s/setuptools/setuptools-0.6c11.tar.gz#md5=7df2a529a074f613b509fb44feefe74e
tar xzf setuptools-0.6c11.tar.gz
cd setuptools-0.6c11/
sudo python2.7 setup.py install

aptitude search libmysqlclient
sudo aptitude install libmysqlclient-dev

Install modules (sqlalchemy, mysqldb)
sudo easy_install-2.7 sqlalchemy
sudo easy_install-2.7 mysql-python

 

不过在make的时候，出现如下错误：

>   Failed to find the necessary bits to build these modules:
>   _bsddb             _hashlib           _ssl
>   _tkinter           bsddb185           dbm
>   dl                 gdbm               imageop
>   sunaudiodev
>   To find the necessary bits, look in setup.py in detect_modules() for the module's name.
>
>
>   Failed to build these modules:
>   crypt              nis


继续网上搜寻解决方案，有人建议试下Python-2.6，试下来，错误相同。



继续搜寻，终于在以下地址找到解决方案。

大致原因如下：

  This is not related to PEP 3149 failures.  Ubuntu 11.04 introduced multiarch
   directories for the underlying shared libraries used to link to the Python
   extension modules.  Unpatched, Python's setup.py does not add the necessary
   multiarch directories to the search paths, so some extensions won't build.

   Ubuntu 11.04's Python packages have been patched to add the correct search
   paths.  Upstream Python 2.7, 3.1, 3.2, and 3.3 have also been patched to
   include the correct search paths, but fixed versions have not been released
   upstream yet.  Python 2.6 won't be patched.

   See issue 11715 for details.

 

找到了病根，也就好对症下药。拿Python-2.7.2试试，果然OK。

 

后面到命令都畅通无阻了。
