Question

我不小心替换了位于/ 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'

我已经看到“AttributeError：'module'对象没有属性'pydebug'”的相关问题，但我仍然无法弄清楚如何解决这个问题。

当我尝试重新安装时出现同样的错误：

$ sudo apt-get install python2.7-minimal

Answer 1

问题在于您正在点击/usr/local/bin/python而不是/usr/bin/python。

您可以通过运行类似...

的方式将其移开

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

...以root身份，或者如果您确定不需要它，那么只需将其删除...

rm /usr/local/bin/python

如果bash仍然尝试运行/usr/local/bin/python，并且正在运行type python打印...

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

...然后执行hash -r清除哈希表。

将/usr/bin/python复制到/usr/local/bin/python并不是一个好主意，否则下次使用apt-get upgrade更新python时可能会遇到问题，即它会更新/usr/bin/python ，但默认情况下仍会运行/usr/local/bin/python。

Answer 2

看起来这与专门用于调试的Python构建有关。

我建议您使用apt-get重新安装Python：

sudo apt-get install --reinstall python2.7

您的问题似乎与this SO question about sys.pydebug

相同

Answer 3

你必须重新安装。这是一个更好的解决方案。这是我在Ubuntu上使用终端安装的favourite。尝试： Install Python and cherrypy

你看看这个问题的答案

Installation python

我的python不起作用
