我使用google-perf工具(tcmalloc)库编译了Python 2.6.6,以消除我使用默认2.6.5时遇到的一些内存问题.在获得2.6.6之后它似乎无法工作,因为我认为在Ubuntu中存在默认2.6.5安装问题.从wxPython和setuptools这样的软件通道安装的二进制文件是否都不能正常使用2.6.6.这些需要重新编译吗?任何其他建议,以使其顺利运作.我可以在不更改路径的情况下将2.6.5设置为默认值吗?该路径首先在usr / local / bin中查找.
一个好的一般经验法则是永远不要使用默认系统安装的Python来进行除杂项系统管理脚本之外的任何软件开发.这适用于所有UNIX,包括Linux和OS / X.
相反,使用您需要的库(Python和C)构建一个您控制的优秀Python发行版,并将此tarball安装在非系统目录中,例如/ opt / devpy或/ data / package / python或/ home /蟒蛇.为什么2.7.2可用时为什么要乱用2.6?
在构建它时,请确保其所有依赖项都在其自己的目录树(RPATH)中,并且任何系统依赖项(.so文件)都将复制到其目录树中.这是我的版本.如果您只运行整个shell脚本,它可能无法正常工作.我总是将其中的部分复制并粘贴到终端窗口中,并验证每个步骤是否正常.确保将终端属性设置为允许大量回滚行,或者一次只粘贴几行.
(实际上,经过一些调整之后我认为这可能会像脚本一样运行,但是我会推荐类似./pybuild.sh> pylog 2>& 1这样你就可以梳理输出并验证所有内容是否正常.
这是建立在Ubuntu 64位上的
