在根目录执行安装命令后，报错，报错内容如下，按照提示，使用 npm install pm2 -g --unsafe-perm命令安装后，依然没办法解决， 所以请问有遇到过类似情况的朋友么？可以帮忙解决下么？ 谢谢！

[root@test nodeclub]# npm install
\
> [email protected] preinstall /alidata/server/nodeclub/node_modules/pm2
> bash ./scripts/preinstall.sh

##### PM2 INSTALLATION
#
#
# As you run PM2 as root, to update PM2 automatically
# you must add the --unsafe-perm flag.
#
#       $  npm install pm2 -g --unsafe-perm
#
# Else run the installation as a non root user
#
