环境 ubuntu18.4 phpstorm php7.2

最正确安装方法                                      （推荐学习：phpstorm）

sudo apt-get install php-codesniffer

composer安装PHP_CodeSniffer   

composer global require "squizlabs/php_codesniffer=*" //这个方法装好后各种问题

配置phpstorm

找到phpcs文件并记住

jiang@jiang:/usr/local$ cd /home/jiang/.config/composer/vendor/bin/jiang@jiang:~/.config/composer/vendor/bin$ ls

 将执行路径加入环境变量vim ~/.bashrc

export PHPCODESNIFFER=/home/jiang/.composer/vendor;
 export PATH=$JAVA_HOME/usr/local/eclipse:$ECLIPSE_HOME:$MAVEN_HOME/bin:$TOMCAT_HOME/bin:$TOMCAT_HOME/bin:$PHPCODESNIFFER/bin:$PATH:
