Question

我收到以下错误，我的节点版本是：12.18 当我运行npm start开始我的项目时

 fs.js:36
  } = primordials;
^

ReferenceError: primordials is not defined
at fs.js:36:5

有人回答说它是与吞咽和节点12（How to fix ReferenceError: primordials is not defined in node）有关的问题

但是我没有在项目中使用gulp，也没有安装gulp。

下面是我的package.json

       {
    "name": "myapp",
    "version": "1.0.0",
    "description": "",
    "scripts": {
      "start": "node server.js",
      "test": "echo \"Error: no test specified\" && exit 1"
    },
    "author": "MJX",
    "license": "ISC",
    "dependencies": {
      "body-parser": "^1.19.0",
      "express": "^4.17.1",
      "express-handlebars": "^2.0.1",
      "mssql": "^6.2.1",
      "mysql": "^2.18.1",
      "nodemon": "^1.19.4",
      "npm": "^5.10.0"
    },
    "devDependencies": {
      "handlebars-helper-css": "^0.1.0"
    }
  }

和我的server.js：

       var express = require("express");
  var bodyParser = require("body-parser");

  var PORT = process.env.PORT || 4300;

  var app = express();

  app.use(express.static("public"));

  app.use(bodyParser.urlencoded({ extended: true }));

  app.use(bodyParser.json());

  var exphbs = require("express-handlebars");

  app.engine("handlebars", exphbs({ defaultLayout: "main" }));
  app.set("view engine", "handlebars");

  var routes = require("./controllers/burgersController.js");

  app.use(routes);

  app.listen(PORT, function() {
    console.log("App now listening at localhost:" + PORT);
  });

如果您查看错误消息中没有提供的堆栈跟踪信息：

ReferenceError: primordials is not defined
    at fs.js:35:5
    at req_ (C:\Users\Patrick\Desktop\test\node_modules\natives\index.js:143:24)
    at Object.req [as require] (C:\Users\Patrick\Desktop\test\node_modules\natives\index.js:55:10)
    at Object.<anonymous> (C:\Users\Patrick\Desktop\test\node_modules\graceful-fs\fs.js:1:37)
    at Module._compile (internal/modules/cjs/loader.js:1138:30)
    at Object.Module._extensions..js (internal/modules/cjs/loader.js:1158:10)
    at Module.load (internal/modules/cjs/loader.js:986:32)
    at Function.Module._load (internal/modules/cjs/loader.js:879:14)
    at Module.require (internal/modules/cjs/loader.js:1026:19)
    at require (internal/modules/cjs/helpers.js:72:18)

您会发现错误源自natives模块。运行npm ls natives，您可以确定它是express-handlebars的子依赖项：

myapp@1.0.0 C:\Users\Patrick\Desktop\test
`-- express-handlebars@2.0.1
  `-- graceful-fs@3.0.12
    `-- natives@1.1.6

您的express-handlebars依赖性已经过时。将其从^2.0.1更新为^5.1.0可以解决您的问题，但您实际上不应忽略其余audit messages：

found 146 vulnerabilities (80 low, 15 moderate, 51 high)
  run `npm audit fix` to fix them, or `npm audit` for details

Answer 2

在项目根文件夹中创建一个名为 npm-shrinkwrap.json 的文件。

将代码添加到文件中：

{
"dependencies": {
 "graceful-fs": {
     "version": "4.2.2"
  }
}
}

我得到错误：fs.js：36} = primordials; ^ ReferenceError：未定义primordials
