嘗試通過 yarn 和 pm2 啟動應用程序時出錯

Question

嘗試通過 yarn 和 pm2 啟動節點 (next.js) 應用程序時收到錯誤。 我的 google fu 沒有找到任何有用的東西。 我懷疑問題出在 nvm 上，盡管我沒有足夠的經驗來理解如何修復它。

Ubuntu 20.04
nvm 0.38.0
節點 v14.5.0
紗線 1.22.10
pm2 4.5.6

生態系統.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",
        }
    }
]

}

通過以下方式啟動文件：

pm2 start ecosystem.config.js --env staging

或者

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

接收錯誤：

Answer 1

--interpreter bash是你的問題。 yarn不是 bash 腳本，而是似乎是 JS 程序。 做這個：

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

Answer 2

我發現唯一的解決方案是通過定義一個特定的端口來運行它，在我的例子中是 3000，感謝 Brandon Aguilar 的評論。 這就是命令

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

似乎默認情況下它將它運行到端口 80
