我按老师的来为什么pwd有三个值呢，最后报错了

+ TOMCAT_APP_PATH=/root/apache-tomcat-9.0.14
++ pwd
+ export 'PROJ_PATH=/root/ /root/.jenkins/ /root/.jenkins/workspace/testenv'
+ PROJ_PATH='/root/ /root/.jenkins/ /root/.jenkins/workspace/testenv'
+ sh /root/ /root/.jenkins/ /root/.jenkins/workspace/testenv/order/deploy.sh
/root/: /root/: is a directory
