node.js:找不到模块“请求" [英] node.js: cannot find module 'request'

问题描述

我安装了请求模块，并收到错误消息:

I installed request module, and getting the error:

module.js:340
    throw err;
          ^
Error: Cannot find module 'request'

我已经阅读了有关此错误的所有文章，并了解到这是因为模块请求未在全球范围内找到，但是我已经尝试了2条建议

i've read all the posts about this error, and understand that this is because module requests is not globally found, but i've already tried the 2 suggestions

npm安装请求-g

npm install request -g

该将其安装在/usr/loca/bin中吗?因为我在那里看不到.

should this install it in /usr/loca/bin ? because i don't see it there.

和

sudo npm链接

sudo npm link

/usr/local/lib/node_modules/request->/Users/soulsonic/dev/sandbox/node_test/request

/usr/local/lib/node_modules/request -> /Users/soulsonic/dev/sandbox/node_test/request

我在每条命令后重新启动终端，但始终收到找不到模块的错误.

i restarted terminal after each command, but keep getting the cannot find module error.

更新

我的初始目录中肯定存在某种冲突，因为"npm install request"没有在node_modules下添加"request"(那里还有10个). 切换到新目录后，它就可以正常工作了.

there must have been some sort of conflict in my initial directory, because "npm install request" was not adding "request" under node_modules (there 10 others in there) .. after switching to a new directory it just worked.

如果我使用-g开关运行它，我确实看到它已安装到/usr/local/lib/node_modules/request.

if i run it with -g switch, i do see it bing installed to /usr/local/lib/node_modules/request.

似乎我只需要更新我的个人资料，即可自动添加以上路径.

it seems that i just need to update my profile so that above path is automatically added.

推荐答案

转到项目目录

mkdir TestProject
cd TestProject

将此目录设为项目的根目录(这将创建一个默认的package.json文件)

Make this directory a root of your project (this will create a default package.json file)

npm init --yes

安装所需的npm模块并将其另存为项目依赖项(它将出现在package.json中)

Install required npm module and save it as a project dependency (it will appear in package.json)

npm install request --save

使用包示例中的代码在项目目录中创建test.js文件

Create a test.js file in project directory with code from package example

var request = require('request');
request('http://www.google.com', function (error, response, body) {
  if (!error && response.statusCode == 200) {
    console.log(body); // Print the google web page.
  }
});

您的项目目录应如下所示

Your project directory should look like this

TestProject/
- node_modules/
- package.json
- test.js

现在只需在项目目录中运行节点

Now just run node inside your project directory

node test.js
