npm install forever出错

出现node版本过低，无法安装npm

apt-get install nodejs-dev node-gyp libssl1.0-dev -y

然后安装npm

apt-get install npm -y

在使用npm安装forever时候报错：

npm WARN deprecated [email protected]: Chokidar 2 will break on node v14+. Upgrade to chokidar 3 with 15x less dependencies.
npm WARN deprecated [email protected]: Please see https://github.com/lydell/urix#deprecated

npm WARN optional Skipping failed optional dependency /chokidar/fsevents:

ubuntu下没有forever命令，就没有安装上，清理cache后

sudo npm cache clean

继续运行

sudo npm install forever -g

终于安装上了，虽然还是出现一些警告
