Question

我想用ipython运行python脚本，我需要导入lmfit包。在工作中，我有一台Windows电脑，一切都在那里工作。但我的私人电脑有ubuntu 14.04，我甚至无法安装lmfit包。我安装了python 3.4.3和python 2.7.6。我试着用pip

pip3 install lmfit

我得到的是：

我也试过

sudo apt-get install python-lmfit

据说它告诉我找不到lmfit。

我真的不是那些安装问题的专家。当我安装python并且一切正常时，我感到非常高兴。所以请原谅我这个愚蠢的问题。

谢谢！

Answer 1

因为pip命令无权在/usr/local/

中写dirs

所以你应该试试sudo pip3 install lmfit

如果您的ipython安装在py2下，请尝试sudo pip2 install lmfit

Answer 2

通过键入sudo pip3 install lmfit，如果您的终端机说from pip import main [...] ImportError: cannot import name 'main'，则可以通过sudo python3 -m pip uninstall pip && sudo apt install python3-pip --reinstall全新安装pip3来解决问题，如此处的link
