我试图在开发者模式下在cr-48 chromebook上安装Python2.7,并面临一个奇怪的问题,即我很难在谷歌上搜索解决方案.首先是一些背景..根分区是readonly挂载的,所以我一直在/usr/local下安装包,这是一个可写的独立挂载点.有一种方法可以强制root分区本身readwrite(有一些小的缺点),但我决定不去那条路.我一直在下载archlinux软件包并在/usr/local下提取它们,其中一些已经很好地工作了.我基本上提取.tar.xz文件有点像这样：

xz -dc package.tar.xz | sudo tar --strip-components=1 -C /usr/local -xvf -

这基本上将发往/ usr的文件放在/usr/local下.我在LD_LIBRARY_PATH下的/usr/lib之前导出/usr/local/lib,并通过这种方式获得了几个包.由于某种原因,python无法加载识别它,虽然不完全确定是什么原因造成的.在扩展了我从archlinux site获得的python 2.7软件包之后,我能够很好地启动python shell,并且简单的打印工作正常.然后我尝试安装setuptools,所以从pypy下载了源代码并尝试运行sudo /usr/local/python2 setup.py install,但它一直给我以下错误：

/usr/local/bin/python2: error while loading shared libraries: libpython2.7.so.1.0: cannot open shared object file: No such file or directory

libpython2.7.so.1.0文件位于/usr/local/lib /目录中,该文件位于LD_LIBRARY_PATH中.快速运行的ldd清楚地显示了这一点：

chronos@localhost /tmp/setuptools-1.1.6 $ldd /usr/local/bin/python2
        linux-gate.so.1 (0x777a9000)
        libpython2.7.so.1.0 => /usr/local/lib/libpython2.7.so.1.0 (0x77610000)
        libpthread.so.0 => /lib/libpthread.so.0 (0x775ee000)
        libc.so.6 => /lib/libc.so.6 (0x77464000)
        libdl.so.2 => /lib/libdl.so.2 (0x77460000)
        libutil.so.1 => /lib/libutil.so.1 (0x7745b000)
        libm.so.6 => /lib/libm.so.6 (0x77436000)
        /lib/ld-linux.so.2 (0x777aa000)

我还检查了/etc/ld.so.conf,这也有/usr/local/lib：

chronos@localhost /tmp/setuptools-1.1.6 $cat /etc/ld.so.conf 
# ld.so.conf autogenerated by env-update; make all changes to
# contents of /etc/env.d directory
/lib
/usr/lib
/usr/local/lib
/usr/lib/opengl/xorg-x11/lib

我安装了strace(和perl,因为它被列为依赖项),并在strace下运行install命令,显示下面有趣的输出(请参阅它不是在寻找/usr/local/lib/libpython2.7.so.1.0任何地方)：

chronos@localhost /tmp/setuptools-1.1.6 $sudo strace /usr/local/bin/python2 setup.py installPassword:

我总是通过在LD_LIBRARY_PATH中包含lib路径并导出它来获得自定义安装路径,因此不确定我还能在这里找到什么.任何帮助深表感谢.

解决方法:

除了LD_LIBRARY_PATH之外,您可能还需要设置一些特定于Python的环境变量,例如PYTHONHOME& PYTHONPATH.有关详细信息,请参阅Python man page.

安装新库后,您可能还需要以root身份运行ldconfig以更新库高速缓存文件.

另一个尝试的选项是设置环境变量RUN_LD_PATH,甚至可以使用-rpath或-rpath-link编译器/链接器选项.

您也可以尝试预先链接/usr/local下的所有可执行文件和库,尽管这可能很繁琐,因为这些目录可能未在/etc/prelink.conf中列出.也许只是从你的python可执行文件开始.
