Your pandasis installed here:
你pandas安装在这里：
/usr/local/python3.4/lib/python3.4/site-packages
But this path is not in sys.path.
但是这条路不在sys.path.
As a workaround do:
作为一种解决方法：
export PYTHONPATH=$PYTHONPATH:/usr/local/python3.4/lib/python3.4/site-packages
and inside this terminal start Python again and do your import of pandas.
并在此终端内再次启动 Python 并导入pandas.
If this works, add this line above (export PYTHONPATH...) to your ~/.bashrcor equivalent if you use a different shell for a more permanent solution.
如果可行，如果您使用不同的 shell 以获得更持久的解决方案，请将上面 ( export PYTHONPATH...)行添加到您的~/.bashrc或等效的行中。
