尝试通过yarn和pm2启动应用程序时出现错误

Question

尝试通过yarn和pm2启动节点（next.js）应用程序时收到错误。我的谷歌搜索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了解如何修复它。

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

生态系统.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

或者

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

接收错误：

Answer 1

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

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