我正在尝试使用Pythonbrew构建多个版本的python,但是我遇到了一些测试失败.这是在运行的VM上:Ubuntu 8.04 32位
当我使用–enable-shared选项时会发生这种情况
build.log文件错误如下所示:

解决方法:
目前,我设法让pythonbrew使用2.7.2执行以下操作:
a)首先,安装编译python所需的所有依赖项.
'curl' # not for build, but for steps after
'build-essential',
'libbz2-dev',
'libsqlite3-dev',
'zlib1g-dev',
'libxml2-dev',
'libxslt1-dev',
'libreadline5', # lenny
'libreadline5-dev', # lenny
'libgdbm-dev',
'libgdb-dev',
'libxml2',
'libssl-dev',
'tk-dev',
'libgdbm-dev',
'libexpat1-dev',
'libncursesw5-dev'
b)现在安装2.7.2:
pythonbrew install --configure="--with-threads --enable-shared" -j2 -v 2.7.2
这安装,但受到以下bug的影响:
/home/python-deploy/.pythonbrew/pythons/Python-2.7.2/bin/python: error
while loading shared libraries: libpython2.7.so.1.0: cannot open
shared object file: No such file or directory
*为避免在构建尝试安装setuptools后出现错误,请使用–no-setuptools选项,并且您可能需要在某些平台上使用–force,因为gdb测试由于测试中的错误而失败本身.
pythonbrew install --configure="--with-threads--enable-shared" \
--force \
--no-setuptools \
--jobs=2 \
--verbose 2.7.2
c)最简单的解决方法是(使用pythonbrew安装的正确路径):
pythonbrew use 2.7.2
export LD_LIBRARY_PATH=$HOME/.pythonbrew/pythons/Python-2.7.2/lib
或者永久添加它,将pythonbrew lib路径放在/etc/ld.so.conf.d下的文件中,路径将在启动时添加,或立即运行ldconfig:
sudo echo /home/user/.pythonbrew/pythons/Python-2.7.2/lib >> /etc/ld.so.conf.d/pythonbrew.conf
sudo ldconfig
d)安装setuptools或手动分发,即
curl -O http://python-distribute.org/distribute_setup.py
python distribute_setup.py && easy_install pip
你应该准备好了.仅在臭名昭着的debian lenny VM上使用2.7.2进行测试.
