在我的电脑上装有Python2版本的ipython虚拟环境,和Python3版本的虚拟环境.
#+BEGIN_SRC ipython :preamble # -*-
coding: utf-8 -*- :results raw drawer values list :exports both :session
import sys
sys.version
#+END_SRC
运行改代码判断, 可以正确的输出ipython的版本2.7.10. 但是当我使用virtualwapper.el的命令venv_workon将虚拟环境切换至Python3后,并将#+BEGIN_SRC ipython…中的ipython修改成python后,再次运行该代码片段,并没有任何效果.相反的当再复原成#+BEGIN_SRC ipython…,并再使用venv_workon命令切换回ipython虚拟环境后,运行结果产生了错误,是ob-ipython提示的:Json error:josn readtable error. 在Github上查找相关的issue,也没有能够解决该提示错误的方法? ob-ipython的作者也没有给出答案? 我不知道我这样的做法对不对,如果有更好的解决方案能否分享?
我的配置,虚拟环境切换用的virtualwapper.el,运行ipython用的ob-ipython.el.
