在亚马逊Linux上运行pm2时出现“语法错误意外令牌...”

问题描述

我已经安装了nodejs提供的amazon-extras：

sudo amazon-linux-extras install -y epel
yum install -y nodejs
node --version

现在就安装pm2：

sudo npm install pm2@latest -g

/usr/bin/pm2 -> /usr/lib/node_modules/pm2/bin/pm2
/usr/bin/pm2-dev -> /usr/lib/node_modules/pm2/bin/pm2-dev
/usr/bin/pm2-docker -> /usr/lib/node_modules/pm2/bin/pm2-docker
/usr/bin/pm2-runtime -> /usr/lib/node_modules/pm2/bin/pm2-runtime
/usr/lib
└── pm2@4.5.0 

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@~2.1.2 (node_modules/pm2/node_modules/chokidar/node_modules/fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@2.1.3: wanted {"os":"darwin","arch":"any"} (current: {"os":"linux","arch":"x64"})
npm WARN ws@7.2.5 requires a peer of bufferutil@^4.0.1 but none was installed.
npm WARN ws@7.2.5 requires a peer of utf-8-validate@^5.0.2 but none was installed.

这似乎还可以。但是随后运行 pm2并不高兴：

$ pm2
/usr/lib/node_modules/pm2/node_modules/chalk/source/index.js:103
    ...styles,^^^
SyntaxError: Unexpected token ...

    at require (internal/module.js:20:19)
    at Object.<anonymous> (/usr/lib/node_modules/pm2/constants.js:10:14)

此问题和解决方法是什么？

解决方法

运行兼容的 pm2 版本，这对我有用：

npm 安装 pm2@^3

,

这很可能是由于node上amazon linux的默认版本就像过时的

$ node --version
v6.17.1

当我弄清楚如何获得铜器时代（与石器时代）节点版本时，此答案将得到更新。
