Question

我在Windows 8上运行express。我运行了命令

>express app

运行命令后安装依赖项

>cd app && npm install

在我尝试使用给定命令运行应用程序

之后

>DEBUG=my-application ./bin/www

但我收到了错误消息

'Debug' is not recognized as an internal or external command,
operable program or batch file.

有关如何解决此问题的任何想法？一些背景信息，我从他们的网站成功安装了node.js.我尝试使用命令

安装express

>npm install

当我没有工作时，我按照本网站https://coderwall.com/p/mbov6w的指示进行操作。当我没有工作时，我使用以下命令，它工作

npm install -g express-generator@3

我也在快递网站上创建了自己的package.json和app.js，现在我被卡住了。

Answer 1

首先，您必须将DEBUG设置为环境变量：

set DEBUG=my-application

然后，您可以运行该应用程序：

node bin/www

Answer 2

在项目的根文件夹中，您必须运行此命令

对于Windows：

set DEBUG=express:* & node bin/www

Answer 3

对Windows执行以下步骤：

转到您的应用程序，即cd app
npm install
设置DEBUG = app
npm start

默认情况下它将开始侦听端口3000。

Answer 4

对于Windows：将package.json文件中的启动命令更改为

"scripts": {
    "start": "set DEBUG=my-application & node ./bin/www"   
}

然后您可以运行npm start。无需先在cmd窗口中设置DEBUG环境变量。

Answer 5

对于Windows环境，您需要使用SET VARIABLE例如

"scripts" : {
   "start" : "SET DEBUG=app & node ./bin/www"
}

这将对Windows env有所帮助，但是如果您要使用跨平台，我建议安装此库cross-env，该库将帮助您设置Windows和Linux环境的变量。并且json应该看起来像这样：

"scripts" : {
    "start" : "cross-env DEBUG=app & node ./bin/www"
}

我遇到了同样的问题，这对我有帮助！

Answer 7

在package.json上使用此设置

对于窗口用户。

  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "start": "set DEBUG=app & node app.js"
  },

对于Mac用户

  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "start": "DEBUG=app node app.js"
  },

app 是您的应用名称，例如[app.js] [server.js]等。
