如何解决在 Windows 上的 PM2 中启动应用程序的问题？

Question

我正在尝试通过 IIS10 上的 PM2 在 Windows Server 2016 上使用 Node.js 版本 12.14.0运行Docusaurus 。我正在使用 PM2，因此我可以在服务器重新启动后重新启动应用程序。我现在必须承认，今天是我第一次尝试使用 Node.js，所以请耐心等待。

这通常通过在 Docusaurus 目录中调用来运行。npm run start在测试 Node.js 以及“Hello World”应用程序是否会在服务器重新启动时启动时，我使用了ecosystem.config.jsPM2 文档中建议的方法。这称为一个 javascript 文件，如下所示。

module.exports = {
    apps: [
      {
        name: "HelloWorld",
        script: "apps\\hello_world.js",
        instances: 1
      }
    ]
  }

这工作正常，但我找不到任何有关如何npm start从该文件运行的文档（尽管我确实尝试调用单独的批处理文件，但这也不起作用）。然后我在这里看到我可以调用一个记录了更多选项的 JSON 文件。

JSON 配置文件：

{
    "apps": [
        {
            "name": "docs",
            "cwd": "apps\\docs",
            "script": "npm",
            "args": "start"
        },
        {
            "name": "HelloWorld",
            "script": "apps\\hello_world.js"
        }
    ]
}

“HelloWorld”脚本启动，但文档应用程序不启动。

pm2 报告提供以下输出：

这让我在 GitHub 上看到了这个问题。不过，关于这些问题的活动似乎并不多，而且也有历史性的事件发生。

我认为 PM2 可能做错了什么或者它有问题，因为我也无法通过 PM2 的命令行启动文档。

{
    "apps": [
        {
            "name": "docs",
            "cwd": "apps\\docs",
            "script": "npm",
            "args": "start"
        },
        {
            "name": "HelloWorld",
            "script": "apps\\hello_world.js"
        }
    ]
}

有没有人对我如何让它发挥作用有任何想法或尝试过做类似的事情？我愿意回答以下问题：

• 在 Windows Server 上运行 Docusaurus 的另一种方法。
• 使用 PM2.5 的替代方案。
• 任何其他想法。

如果我胡言乱语，抱歉。

它引用的日志是空的。多次重复docs-error.log同样的错误，但从昨晚开始就没有更新了。它可能是我在 JSON 文件中尝试不同的语法创建的，但还是发布了它。

C:\Node JS\apps\docs>pm2 start npm --name "docs" -- start

问题实际上是 pm2 如何通过 Windows 上的批处理文件调用节点。如果您npm-cli.js直接使用其完整路径调用，程序将正常运行。

{
    "apps": [
        {
            "name": "docs",
            "cwd": "some_path_to\\apps\\docs",
            "script": "C:\\Program Files\\nodejs\\node_modules\\npm\\bin\\npm-cli.js",
            "args": "start",
            "exec_mode": "cluster",
            "instances": 1,
            "interpreter": "none"
        }
    ]
}
