打开文件编辑器：
进入终端，输入open -e .bash_profile或者open -t ~/.bash_profile 打开profile文件
填写配置的环境变量：
#示例代码
export PATH=$PATH:/usr/local/bin export ANDROID_HOME=/Users/lucky/Desktop/Auto/tools/android-sdk-macosx PATH=${PATH}:$ANDROID_HOME/tools:$ANDROID_HOME/platform_tools echo $ANDROID_HOME PATH="/Library/Frameworks/Python.framework/Versions/2.7/bin:${PATH}" export PATH export JAVA_HOME=$(/usr/libexec/java_home) export PATH=$JAVA_HOME/bin:$PATH export CLASS_PATH=$JAVA_HOME/lib export PATH=$PATH:$ANDROID_HOME/platform-tools export PATH=$JAVA_HOME/bin:$PATH:/Users/lucky/Desktop/Auto/tools/apache-tomcat-9.0.8/bin export ANT_HOME=/Users/lucky/Desktop/Auto/tools/apache-ant-1.10.3 export PATH=$PATH:$JAVA_HOME/bin:$ANT_HOME/bin # Add Cmake Root to Path
export CMAKE_ROOT=/Applications/CMake.app/Contents/bin export PATH=$CMAKE_ROOT:$PATH export PATH="/usr/local/opt/freetds@0.91/bin:$PATH" PATH="/usr/local/mysql/bin:${PATH}" export PATH export DYLD_LIBRARY_PATH=/usr/local/mysql/lib/ export VERSIONER_PYTHON_PREFER_64_BIT=yes export VERSIONER_PYTHON_PREFER_32_BIT=no # Setting PATH for Python 3.7 # The original version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/3.7/bin:${PATH}" export PATH
保存配置：
编辑完成后保存profile文件后保存，返回终端，输入source .bash_profile使环境变量生效
