尝试通过 yarn 和 pm2 启动应用程序时出错

Question

尝试通过 yarn 和 pm2 启动节点 (next.js) 应用程序时收到错误。我的 google fu 没有发现任何有用的东西。我怀疑问题出在 nvm 上，尽管我没有足够的经验来理解如何修复它。

Ubuntu 20.04
nvm 0.38.0
节点 v14.5.0
纱线 1.22.10
pm2 4.5.6

ecosystem.config.js

module.exports = {
  apps: [
    {
        name: "next",
        script: "yarn",
        interpreter: "bash",
        args: "start:next",
        instances: 1,
        env: {
            NODE_ENV: "development",
        },
        env_staging: {
            NODE_ENV: "production",
        },
        env_production: {
            NODE_ENV: "production",
        }
    }
]

}

通过以下方式启动文件：

pm2 start ecosystem.config.js --env staging

或

pm2 start yarn --interpreter bash --name next -- start:next

接收错误：

Answer 1

--interpreter bash 是你的问题。 yarn 不是 bash 脚本，而是一个 JS 程序。这样做：

pm2 start yarn --name appname -- start:next

Answer 2

我发现唯一的解决方案是运行通过定义一个特定的端口，在我的例子中是 3000，感谢 Brandon Aguilar 的评论。就是这个命令

pm2 start yarn --name appname -- start -p 3000

似乎默认它运行它到端口 80
