mac下python3安装

操作系统: macOS Mojave 版本 10.14

 

通过brew安装,命令行下输入brew install python, 一段时间后提示:

Error: An unexpected error occurred during the `brew link` step

The formula built, but is not symlinked into /usr/local

Permission denied @ dir_s_mkdir - /usr/local/Frameworks

Error: Permission denied @ dir_s_mkdir - /usr/local/Frameworks

 

解决方法:

命令行下依次执行如下3个命令

sudo mkdir /usr/local/Frameworks

sudo chown $(whoami):admin /usr/local/Frameworks

brew link python3

完成后输入: brew reinstall python重新安装,成功

 

最后,在终端下输入python3,验证是否安装成功,以及安装的python版本
