Ubuntu 14.04下安装python软件包lmfit的问题

Question

我想用ipython运行一个python脚本，我需要导入lmfit软件包。在工作中，我有一台Windows电脑，一切工作在那里。但我的私人电脑有Ubuntu 14.04，我甚至无法安装lmfit软件包。我同时安装了python 3.4.3和python 2.7.6。我试着用PIP

pip3 install lmfit

什么，我得到的是：

Storing debug log for failure in /home/kristin/.pip/pip.log 

我也试过

sudo apt-get install python-lmfit 

有了它告诉我，lmfit无法找到。

我真的不是那些安装问题的专家..我很高兴当我安装python和一切工作。所以请原谅我这个愚蠢的问题。

谢谢！

由于PIP命令有没有权利写在显示目录/usr/local/

所以，你应该尝试sudo pip3 install lmfit

如果您的IPython下PY2安装，尽量sudo pip2 install lmfit
