即使在MAC OSX El Capitan上正确安装后，也无法在ipython笔记本中导入Pandas

Question

我已经通过conda install pandas安装了pandas，但是在通过ipython jupyter笔记本导入pandas库时仍然收到这个错误。在

我也试着通过

print ('version:' + np.__version__)

并追踪到系统可执行文件从这个目录

^{pr2}$

并具有正确的数据目录路径。在

from jupyter_core.paths import jupyter_data_dir
print(jupyter_data_dir())

将熊猫作为pd导入

尝试将以下参数添加到~/.bash_profile（通过在terminal中键入以下内容）：

export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8
