these instructions在我的运行Mac OSX High Sierra的MacBook上安装带有Homebrew的Python 3.

我在这一步遇到了麻烦：

Once you’ve installed Homebrew, insert the Homebrew directory at the top of your PATH environment variable. You can do this by adding the following line at the bottom of your ~/.profile file

export PATH=/usr/local/bin:/usr/local/sbin:$PATH

在更新〜/ .profile并运行python –version之后,我仍然看到Python 2.7.10.

这似乎是个问题,因为当我按照next page使用pip install –user pipenv安装虚拟环境时,安装完成后会收到以下警告：

The scripts pewtwo, pipenv and pipenv-resolver are installed in ‘/Users/charliesneath/Library/Python/2.7/bin’ which is not on PATH.

看起来我的系统没有正确地优先安装Homebrew的Python 3安装.

我怎样才能解决这个问题？

最佳答案 对于Mac,当您安装python3时,它将安装在与您引用的示例不同的路径中.要找出python3的安装位置,请键入命令行：

which python3

它将返回/Library/Frameworks/Python.framework/Versions/3.6/bin/python3.

将以下行添加到.bash_profile：

PATH="/Library/Frameworks/Python.framework/Versions/3.6/bin:${PATH}"
export PATH
