Question

我以前在python2.7上安装了ipython。我使用

安装python3-pip后

$sudo apt-get install python3-pip

并运行以下命令

$sudo pip3 install ipython

，我无法启动ipython。我收到以下错误：

kv@kv:~$ ipython


Traceback (most recent call last):
  File "/usr/local/bin/ipython", line 7, in <module>
    from IPython import start_ipython
  File "/usr/lib/python2.7/dist-packages/IPython/__init__.py", line 43, in <module>
    from .config.loader import Config

Original exception was:

如何在ipython和python2.7

下python3.4开展工作

更新：

kv@kv:~$ ipython2
No command 'ipython2' found, did you mean:
 Command 'python2' from package 'python-minimal' (main)
 Command 'ipython' from package 'ipython' (universe)
 Command 'ipython3' from package 'ipython3' (universe)
ipython2: command not found

和kv@kv:~$ ipython3 我收到前面提到的错误

Answer 1

对我来说，下面的命令可以移动b / w python版本。

启动ipyton for python 2

$ ipython2

启动ipython for python 3

$ ipython3

ipython无法启动
