你好，我在使用Mac OS Mavericks，最近对Python的安装做了一些调整，想让系统的python命令显示更新后的Python 3.4.1版本。但现在看起来有点乱。当我在终端输入

时，得到的结果是这样的。

我想问的是，怎么才能把系统里其他版本的Python都删掉，只保留最新的Python 3.4.1？而且我不想用homebrew或macports来安装。接下来，安装完Python后，怎么才能安装pip？最后，我想把系统的python命令改成读取python3。也就是说，如果我在系统里输入python -v，应该显示Python 3.4.1的版本信息。

首先，关于“我想知道如何从系统中删除所有其他版本的Python，只保留最新的版本Python 3.4.1”这个问题，

千万不要这样做！如果你把苹果自带的Python版本删掉，你的系统可能会变得无法使用。

1) 从Python官网安装Python 3.x。

2) 把你自定义安装的路径添加到你的.profile文件中。以下是我在.profile中的设置：

#PYTHON
export PATH=/Library/Frameworks/Python.framework/Versions/2.7/bin/:$PATH
export PATH=/Library/Frameworks/Python.framework/Versions/3.3/bin/:$PATH

3) 重启电脑。现在当你输入“python3”时，系统会找到并使用你安装的版本，而不是苹果自带的版本。

4) 如果你觉得每次输入“python3”很麻烦，可以在.profile文件中添加 alias py3=python3，这样你只需输入 py3 就能调用python3。我不建议把 python 设置别名，因为那样如果需要使用python2就不方便了。

5) 这里是pip安装的说明： https://pip.pypa.io/en/latest/installing.html#install-or-upgrade-pip
