我的python不起作用

Question

我意外地替换了位于/ usr/local/bin /的python二进制文件。从那以后，我无法运行任何python脚本，甚至不能运行python的交互模式。

$ python 
Traceback (most recent call last): 
    File "/usr/lib/python2.7/site.py", line 562, in <module> 
    main() 
    File "/usr/lib/python2.7/site.py", line 544, in main 
    known_paths = addusersitepackages(known_paths) 
    File "/usr/lib/python2.7/site.py", line 271, in addusersitepackages 
    user_site = getusersitepackages() 
    File "/usr/lib/python2.7/site.py", line 246, in getusersitepackages 
    user_base = getuserbase() # this will also set USER_BASE 
    File "/usr/lib/python2.7/site.py", line 236, in getuserbase 
    USER_BASE = get_config_var('userbase') 
    File "/usr/lib/python2.7/sysconfig.py", line 558, in get_config_var 
    return get_config_vars().get(name) 
    File "/usr/lib/python2.7/sysconfig.py", line 457, in get_config_vars 
    _init_posix(_CONFIG_VARS) 
    File "/usr/lib/python2.7/sysconfig.py", line 303, in _init_posix 
    makefile = _get_makefile_filename() 
    File "/usr/lib/python2.7/sysconfig.py", line 297, in _get_makefile_filename 
    return os.path.join(get_path('platstdlib').replace("/usr/local","/usr",1), "config" + (sys.pydebug and "_d" or ""), "Makefile") 
AttributeError: 'module' object has no attribute 'pydebug' 

我看到了相关的问题“AttributeError的：‘模块’对象有没有属性‘pydebug’”的错误，但我仍然无法弄清楚如何来解决这个问题。

当我尝试重新安装将出现相同的错误：

Answer 1

的问题是，你打/usr/local/bin/python代替/usr/bin/python。

您可以将其移出的方式运行类似...

mv /usr/local/bin/python /usr/local/bin/python.old 

...为根，或者如果你确定你不需要它，那么就删除它与...

rm /usr/local/bin/python 

如果仍然庆典尝试运行/usr/local/bin/python和运行type python打印...

python is hashed (/usr/local/bin/python) 

...然后执行hash -r来清除哈希表。

这并不是/usr/bin/python复制到/usr/local/bin/python一个好主意，否则你可能会得到问题的下一次你apt-get upgrade更新蟒蛇，即它会更新/usr/bin/python，但/usr/local/bin/python仍然会被默认运行。

您必须重新安装。 这是一个更好的解决方案。 这是我在Ubuntu上使用终端的最佳安装。 尝试： Install Python and cherrypy

而且你看看答案在这个问题上

Installation python

Answer 3

貌似这个事做与调试特制一个Python版本。

我建议你重新安装Python和apt-get的：

sudo apt-get install --reinstall python2.7
