在Ubuntu 10.4上安装Python-2.7

Question

我似乎无法正确安装zlib，我在Ubuntu10.4上从源代码安装了Python

确保安装了这些软件包，然后重新编译Python：
sudo aptitude install zlib1g-dev libreadline6-dev libdb4.8-dev libncurses5-dev
‘###################### ############

安装后，我尝试安装setuptools.py

$ sh setuptools-0.6c11-py2.7.egg   
Traceback (most recent call last):  
  File "<string>", line 1, in <module>  
zipimport.ZipImportError: can't decompress data; zlib not available

然后我安装了zlib：

$ sudo aptitude install zlibc

重新编译Python之前：

但是setuptools仍然无法安装：

$ sh setuptools-0.6c11-py2.7.egg   
Traceback (most recent call last):  
  File "<string>", line 1, in <module>  
zipimport.ZipImportError: can't decompress data; zlib not available

我很困惑。

我检查了我的权限：

lrwxrwxrwx 1 root      18 Oct 28 18:19 /usr/bin/python -> /usr/bin/python2.7
lrwxrwxrwx 1 root      24 Oct 28 18:26 /usr/bin/python2.7 -> /usr/local/bin/python2.7
lrwxrwxrwx 1 root       9 Oct 28 15:13 /usr/bin/python2 -> python2.6
-rwxr-xr-x 1 root 2613296 Apr 16  2010 /usr/bin/python2.6

我注意到我添加了一个额外的步骤，因此我对其进行了重构：

llrwxrwxrwx 1 root      24 Oct 28 18:33 /usr/bin/python -> /usr/local/bin/python2.7  
lrwxrwxrwx 1 root       9 Oct 28 15:13 /usr/bin/python2 -> python2.6  
-rwxr-xr-x 1 root 2613296 Apr 16  2010 /usr/bin/python2.6

所以现在，Python2.7应该是默认版本，但仍然失败。

$ sh setuptools-0.6c11-py2.7.egg --prefix=/usr/local/bin/python2.7  
Traceback (most recent call last):  
  File "<string>", line 1, in <module>  
zipimport.ZipImportError: can't decompress data; zlib not available

zlib应该位于哪里才能正常工作？

$ find / -name zlib 2>/dev/null  
/home/username/sources/Python-2.7/Modules/zlib  
/home/username/sources/Python-2.7/Demo/zlib

username@servername Thu Oct 28 18:43:17 ~/sources   
$ find / -name zlibc 2>/dev/null  
/usr/share/lintian/overrides/zlibc  
/usr/share/doc/zlibc

您不想要zlibc，这完全是另外一回事。您需要zlib1g（肯定已经安装了），并且正如Luper所提到的，开发包是zlib1g-dev。

基于Debian的Linux发行版将每个C库分为一个单独的运行时二进制包和一个开发包，该包提供在编译时包含的标头。如果要从源代码中编译依赖于库的内容，则需要两个软件包。有点烦，但是考虑到Ubuntu之类的库数量惊人，这可能是不可避免的。

请确保你在其他带-dev包，你可能想Python中可以使用，也如libexpat1-dev，libdb4.8-dev，libncurses5-dev和libreadline6-dev（使用Python解释器没有的ReadLine是痛苦的！）。然后，您必须重新编译Python以利用它们。

（或者，如果您不打扰，您可能会忘记setuptools，而只是解压缩您自己的任何最终应用程序，然后将其放入站点包中或任何地方。不得不说我不是鸡蛋的忠实粉丝。）
