1、启动客户端项目报错
当前Node.js版本：v10.13.0
启动H5项目客户端，抛如下异常：
[webpack-cli] /Users/maomao/Documents/demo/pc/askteam/node_modules/webpack-dev-server/lib/servers/WebsocketServer.js:10
static heartbeatInterval = 1000;

尝试切换到更低Node版本v8.17.0
又报如下错误：

关键是之前都能正常启动。
所以我怀疑是本地Node版本问题。
解决办法
以上问题统一解决方案为，将Node.js版本更新到最新。
C02Z84E5LVCF:server maomao$ nvm ls
-> v8.17.0
v10.13.0
v10.23.0
v16.14.0
default -> 8.17.0 (-> v8.17.0)
node -> stable (-> v16.14.0) (default)
stable -> 16.14 (-> v16.14.0) (default)
iojs -> N/A (default)
lts/* -> lts/gallium (-> v16.14.0)
lts/argon -> v4.9.1 (-> N/A)
lts/boron -> v6.17.1 (-> N/A)
lts/carbon -> v8.17.0
lts/dubnium -> v10.24.1 (-> N/A)
lts/erbium -> v12.22.10 (-> N/A)
lts/fermium -> v14.19.0 (-> N/A)
lts/gallium -> v16.14.0
我当前最新版本是v16.14.0,所以切换或安装到v16.14.0版本即可。
切换版本：
nvm use v16.14.0安装版本(需要外网)：
nvm i v16.14.0
