我似乎无法正确安装 zlib,我在 Ubuntu10.4 上从源代码安装了 Python
'######## 编辑 #####################
博宾斯和卢珀帮忙了。
确保安装这些包,然后重新编译 Python:
sudo aptitude 安装 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 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,所以我重构了它:
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 应该放在哪里才能正常工作?
