fatal: not in a git directory

Error: Command failed with exit 128: git

根据这个错误做搜索，发现需要执行以下命令 ：

brew -v

获取如下信息：

Homebrew 3.5.2-113-g5d3501f

fatal: unsafe repository ('/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core' is owned by someone else)

To add an exception for this directory, call:

git config --global --add safe.directory /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core

Homebrew/homebrew-core (no Git repository)

fatal: unsafe repository ('/usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask' is owned by someone else)

To add an exception for this directory, call:

git config --global --add safe.directory /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask

Homebrew/homebrew-cask (no Git repository)

按照上述信息执行：

git config --global --add safe.directory /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core
 
git config --global --add safe.directory /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask

重新执行以下命令：

brew install cmake protobuf rust python@3.10 git wget

 判断python是否安装成功：

python3 -V

安装效果：

Python 3.9.13

修改别名，执行命令

vim ~/.bash_profile 

添加下面信息：

alias python=python3

alias pip=pip3

执行命令：

# 
source .bash_profile 
 
#
python -V 
 
#
pip
