如何在Mac OS 10.13.6中从预安装的python 2.7.10切换到Python 3.7

标签: python python-3.x pip praw

正如大多数在线解决方案所建议的,我做了以下事情:

open -e ~/.bash_profile

并添加了别名python ='python3'

这是我的.bash_profile的样子:

# Setting PATH for Python 3.7
# The original version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/3.7/bin:${PATH}"
export PATH

alias python='python3'

现在在终端上我得到了

Sakets-MacBook-Pro:~ theonlyroy$ python --version
Python 3.7.1

但是,我仍然无法安装pip软件包:

Sakets-MacBook-Pro:~ theonlyroy$ pip install praw

praw requires Python '>=3.4' but the running Python is 2.7.10

我不明白为什么它说Python 2.7.x正在运行,或者我能做些什么来解决它。任何建议表示赞赏,谢谢!
