一、mac OSError: mysql_config not found。

1.安装brew

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"  

2.安装mysql-connector-c

brew install mysql-connector-c

3.配置路径

PATH="$PATH":/usr/local/Cellar/mysql-client/8.0.18/bin/

如果再次安装出现IndexError: string index out of range

cd /usr/local/Cellar/mysql-connector-c/6.1.11/bin/  
# 备份  
cp  mysql_config mysql_config.bak     
chmod u+w mysql_config  
vi mysql_config  

#   :114    找到第114行  
# 将  
#  libs="$libs -l "  
# 替换为  
#  libs="$libs -lmysqlclient -lssl -lcrypto"  
#保存

1.安装gcc
