Question

请在同一台计算机（mac OS 10.6.8）上找到解决此问题的方法：

toto$ python
Python 2.7.9 (v2.7.9:648dcafa7e5f, Dec 10 2014, 10:10:46) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin

>>> import matplotlib.pyplot as plt
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/matplotlib/pyplot.py", line 109, in <module>
    _backend_mod, new_figure_manager, draw_if_interactive, _show = pylab_setup()

    globals(),locals(),[backend_name],0)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/matplotlib/backends/backend_macosx.py", line 24, in <module>
    from matplotlib.backends import _macosx
ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/matplotlib/backends/_macosx.so, 2): Symbol not found: __cg_jpeg_resync_to_restart

对于用户toto。但对于另一个用户，我觉得没有问题：

titi$ python

>>> import matplotlib.pyplot as plt
>>>

任何建议都将非常感谢!!!!

我刚找到灰尘： - （（（由于未知原因，用户toto有〜/ .bash_profile文件：

export PATH=~/bin:/opt/local/bin:${PATH}
export DYLD_LIBRARY_PATH=/opt/local/lib:${DYLD_LIBRARY_PATH}


# Setting PATH for Python 2.7
# The orginal version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/2.7/bin:${PATH}"
export PATH

# Setting PATH for Python 2.7
# The orginal version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/2.7/bin:${PATH}"
export PATH

# Setting PATH for Python 2.7
# The orginal version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/2.7/bin:${PATH}"
export PATH

# Setting PATH for Python 2.7
# The orginal version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/2.7/bin:${PATH}"
export PATH

我通过以下方式更改了此文件：

if [ -f ~/.bashrc ]; then 
    source ~/.bashrc 
fi

在.bashrc中，我只保留别名和命令以进行提示。

现在一切正常:-)））感谢您的建议，这有助于找到路径！
