Python 不加载 _fileio 库

Question

我有一个问题，Python 不加载动态 c 库 _fileio

~ $ python
Python 2.7.1+ (r271:86832, Apr 11 2011, 18:05:24) 
[GCC 4.5.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
Could not open PYTHONSTARTUP
IOError: [Errno 2] No such file or directory: '/home/sven/.pythonrc'
>>> import io
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.6/io.py", line 63, in <module>
    import _fileio
ImportError: No module named _fileio
>>> 

~ $ locate _fileio
/usr/lib/python2.6/lib-dynload/_fileio.so 

~ $ echo $PYTHONPATH
/usr/lib/python2.6/

问候斯文

Answer 1

似乎是一个环境问题，源于这一行:

IOError: [Errno 2] No such file or directory: '/home/sven/.pythonrc'

要解决此问题，请找到 .pythonrc 并确保 .bashrc 文件中的 PYTHONSTARTUP 环境变量指向此文件位置。如果它实际上是正确的，请尝试使用硬编码路径到 /home/sven/.pythonrc 而不是诸如 ~/.pythonrc 之类的路径。

此外，如果我没记错的话，.pythonrc 实际上应该是一个 *.py 文件，但这可能会因发行版而异。
