NODE_PATH NPM 在 windows 10 上启动时抛出错误

Question

我正在尝试按照 https://github.com/michaelcheng429/super-mean-stack

构建一个 MEAN Todo 应用程序

package.json

{
 "name": "ToDoThoughts",
 "version": "1.0.0",
 "description": "",
 "main": "index.js",
 "scripts": {
   "start": "NODE_PATH=$NODE_PATH:./app  node server",
   "dev": "npm start & webpack-dev-server --progress --colors"
 },
 "license": "ISC",
 "dependencies": {
   "angular": "1.4.12",
   "angular-ui-router": "0.3.1",
   "body-parser": "1.15.2",
   "bootstrap": "3.3.7",
   "express": "4.14.0"
 },
 "devDependencies": {
   "babel-core": "6.17.0",
   "babel-preset-es2015": "6.16.0",
   "raw-loader": "0.5.1",
   "webpack": "1.13.2",
   "webpack-dev-server": "1.16.2"
 },
 "engines": {
   "node": "5.5.0"
 }
}

当我在命令提示符下运行命令 "npm run dev" 时出现错误。我也附上了npm.debug.log

Answer 1

"scripts": {
    "start": "node server.js",
    "dev": "start cmd /k \"webpack-dev-server --progress --colors\" & node server.js"
  }

Answer 2

安装节点应安装在您的系统环境变量中，并应在 PowerShell 或 cmd 中使用 node 调用。

这应该意味着无需始终在环境变量中插入节点路径。

确保您还运行以管理员身份使用 PowerShell 或 cmd，这可确保获取系统环境变量。

最后，在您的 package.json 中更改为：

"scripts": {
    "start": "node server.js",
    "dev": "start cmd /k \"webpack-dev-server --progress --colors\" & node server.js"
}

然后运行 npm start 并且您的服务器应该运行ning。

Answer 3

NPM scripts 在调用 NPM 的 shell 中执行。

如果您在 Windows 上使用命令提示符或 Powershell，

NODE_PATH=$NODE_PATH:./app node server 将无法正常运行。如果您已经安装了 Git，那么您应该使用 Git Bash，它应该已经可用。

否则，您可能会安装 MSYS' or Cygwin's Bash shell。

Answer 4

npm 缓存清理然后清除package-lock.json file
