Mac 中同时有三个版本的 Python , 2.7、3.5 和 3.6,但是 terminal 中无法使用 3.5,而 Pycharm 却可以,请问这是为什么?

    不能用是什么意思,你敲 python3.5 回车没反应,还是切到 python3.5 的目录运行不了?

    终端下切到 python3.5 安装位置,手动运行下看看

    Pycharm 也不自带 Python3 啊,应该是你给配的环境变量啊什么的用的 3.5

    ide 配置的绝对路径,终端里面你也用全路径就行

    cd bin
    mv python python.bak
    ln -s pythonXY python

    在 bin 里面的 python* 全都是以软连接的形式存在的 想要改 python 版本自己重建软连接就行了。

    @zhaojjxvi 恩,PyCharm 可以选择 project interpreter,因为之前很多包都装在了 3.5 中
