2、我是在安装setuptools的时候，运行python setup.py install出现的。
3、具体代码间下面：
XXXXX@XXXXXX:~/requests/setuptools-0.6c11$ python setup.py install
running install

Answer 1

你的系统中应该还有其他版本的Python存在，导致_io.so在错误的libpython.so中找不到对应的符号。
建议将自己特定版本的Python安装在HOME目录或/opt等目录，并且不加入PATH中以免影响系统自带Python的工作（很多系统工具会依赖系统自带的Python）。然后使用Virtualenv指定使用你需要的Python版本。
