node.js - 尝试同时运行(npm ERR!代码 ELIFECYCLE npm ERR!)

Question

我正在尝试创建一个从 API 获取数据的全栈 Node 和 Vue 应用程序。我遇到了一个问题，我试图同时运行客户端和服务器，但代码遇到错误。如果我错误地构建了这个问题，请耐心等待，因为我对编码还很陌生!

这是以下错误日志:

[0] Error occurred when executing command: npm run server
[0] Error: spawn cmd.exe ENOENT
[0]     at Process.ChildProcess._handle.onexit (internal/child_process.js:267:19)
[0]     at onErrorNT (internal/child_process.js:469:16)

[1] Error occurred when executing command: npm run client
[1] Error: spawn cmd.exe ENOENT

[1] npm run client exited with code -4058
[0] npm run server exited with code -4058
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! apex-tracker@1.0.0 dev: `concurrently "npm run server" "npm run client"`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the apex-tracker@1.0.0 dev script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

据我所知，程序运行良好，直到到达 package.json 中的“dev”脚本:

{
  "name": "apex-tracker",
  "version": "1.0.0",
  "description": "Apex Legends user statistics tracker",
  "main": "server.js",
  "scripts": {
    "start": "node server",
    "server": "nodemon server",
    "client": "npm run serve --prefix client",
    "dev": "concurrently \"npm run server\" \"npm run client\""
  },
  "author": "Jared Mackay",
  "license": "MIT",
  "dependencies": {
    "concurrently": "^5.0.1",
    "dotenv": "^8.2.0",
    "express": "^4.17.1",
    "morgan": "^1.9.1",
    "node-fetch": "^2.6.0"
  },
  "devDependencies": {
    "nodemon": "^2.0.2"
  }
}

在出现错误之前，当我运行npm run server 命令时，程序运行良好，但是在安装客户端文件夹并添加客户端和开发脚本时，我遇到了错误。

这是我尝试与客户端一起运行的 server.js:

const express = require('express');
const morgan = require('morgan');
const dotenv = require('dotenv');

//Load configuration file
dotenv.config({ path: './config.env' })

const app = express();

//Develper logging
if (process.env.NODE_ENV === 'development') {
    app.use(morgan('dev'));
}

//Profile routes
app.use('/api/v1/profile', require('./routes/profile'));

const port=process.env.PORT || 8000;

app.listen(port, () => {
    console.log(`Server running on ${process.env.NODE_ENV} mode on port ${port}`);
});

我尝试清除 npm 缓存、删除并重新安装 node-modules 以及 package-lock.json，但这会产生更多问题，而不是修复它们。我不得不恢复到旧的 git 提交，现在我陷入了困境。

我认为这个路由 .js 文件不是问题，但这里只是以防万一 profile.js:

const express = require('express');
const router = express.Router();
const fetch = require('node-fetch');

router.get('/:platform/:gamertag', async (req, res) => {
    try {
        const headers  = {
            'TRN-Api-Key': process.env.TRACKER_API_KEY
        }

        const { platform, gamertag } = req.params;

        const response = await fetch(
            `${process.env.TRACKER_API_URL}/profile/${platform}/${gamertag}`, 
            {
                headers
            }
        );

        const data = await response.json();

        if(data.errors && data.errors.length > 0) {
            return res.status(404).json({
                message: 'Profile Not Found'
            });

        }

        res.json(data);
    }   catch (err) {
        console.error(err);
        res.status(500).json({
            message: 'Server Error'
        });
    }
});

module.exports = router;

提前谢谢您!

spawn cmd.exe ENOENT

您的程序不知道在哪里可以找到 cmd.exe。
