mac系统下，Python版本切换问题？

Question

请问各位，电脑里装了两个版本的python，2.7.10和3.5.1，想用pyenv在两个版本中切换。截图如下

明明已经切换到3.5.1了，但用的时候还是2.7.10，怎么解决？谢谢！
试了用global，还是不行。。。

Answer 1

Already solved, you need to add
`export PYENV_ROOT=/usr/local/var/pyenv under the .bash_profile file after installing pyenv
if which pyenv > /dev/null; then eval "$(pyenv init -) "; fi`
After these two lines, source it. Then install 2.7.10 and 3.5.1, and then you can switch normally

Answer 2

tryglobal

Answer 3

pyenv global 3.5.1
