正在编译Python2.6.6并需要外部包wxPython、setuptools等。。。在Ubuntu中

Question

我用googleperf工具（tcmalloc）库编译了python2.6.6，以消除我在默认2.6.5中遇到的一些内存问题。在运行2.6.6之后，它似乎不起作用，因为我认为在Ubuntu中默认的2.6.5安装有问题。从软件频道（如wxPython和setuptools）安装的二进制文件都不能在2.6.6中正常工作吗。这些需要重新编译吗？有什么其他的建议可以让它顺利工作吗。在不更改路径的情况下，是否仍可以将2.6.5设置为默认值？路径首先在usr/local/bin中查找。在

Answer 1

如果从repos编译了2.6.6并安装了2.6.5，那么ubuntu在查找所使用的python时会出现冲突。在

我将此标记为移动到超级用户。在

Answer 2

我很确定您必须将wxPython编译为您想要使用它的Python版本。在wxPython邮件列表上做过类似事情的人总是这样。我认为这适用于大多数包，尤其是如果它们有任何C/C++组件，比如WxPython。根据我的经验，纯Python包有时可以完整地从一个版本转移到下一个版本。在

这里有相当广泛的wxPython构建说明：http://wxpython.org/BUILD-2.8.html

如果遇到任何问题，wxPython邮件列表中的robindunn和其他人会非常有帮助。在

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进行任何软件开发，而不是使用其他系统管理脚本。这适用于所有unix，包括Linux和OS/X

相反，使用所需的库（Python和C）构建一个好的Python发行版，并将这个tarball安装在非系统目录中，例如/opt/devpy或/data/package/Python或/home/Python。既然2.7.2可用，为什么还要在2.6上乱搞呢？在

在构建它时，请确保它的所有依赖项都在它自己的目录树（RPATH）中，并且任何系统依赖项（.so文件）都被复制到它的目录树中。这是我的版本。如果只运行整个shell脚本，它可能不起作用。我总是将这部分内容复制并粘贴到终端窗口中，并验证每个步骤是否正常工作。确保您的终端属性设置为允许许多行的滚动，或者一次只粘贴几行。在

（实际上，在做了一些调整之后，我认为它可以作为脚本运行，但是我建议使用./pybuild.sh >pylog 2>&1这样您就可以梳理输出并验证是否所有构建都正常。在

这是建立在64位的Ubuntu上的
