以前基础不扎实- -
现在定义一个环境变量都挺难受
1 #InstallJammer 2 MY_INSTALLJAMMER_PATH=/home/shivency/tools/installjammer 3 export PATH=$MY_INSTALLJAMMER_PATH:$PATH
第二行那儿guide上之前有一个$，弄了好久发现是坑爹的- -
测试：
which installjammer
/home/shivency/tools/installjammer/installjammer
测试：
MY_INSTALLJAMMER_PATH/installjammer
bash: MY_INSTALLJAMMER_PATH/installjammer: No such file or directory
测试：
$MY_INSTALLJAMMER_PATH/installjammer
结果那货自己给弹出来了！！！
