以太坊Web3.js返回“无法找到模块'web3-requestManager'”

I'm trying to start using Ethereum Web3.js with node 6.11.1 on a macosx

我正在尝试在macosx上使用带有节点6.11.1的Ethereum Web3.js

I installed web3 with the following command:

我使用以下命令安装了web3：

npm install web3

npm安装web3

Then i launch this - apparently - simple node command:

然后我启动这个 - 显然 - 简单的节点命令：

Web3 = require('web3');

Web3 = require（'web3'）;

Well, it returns the following error:

好吧，它返回以下错误：

module.js:471
    throw err;
    ^

Error: Cannot find module 'web3-requestManager'
    at Function.Module._resolveFilename (module.js:469:15)
    at Function.Module._load (module.js:417:25)
    at Module.require (module.js:497:17)
    at require (internal/module.js:20:19)

    at Module.load (module.js:487:32)
    at tryModuleLoad (module.js:446:12)
    at Function.Module._load (module.js:438:3)

it looks like it require some module (e.g. 'web3-requestManager') that aren't installed with the package.

看起来它需要一些未随包安装的模块（例如'web3-requestManager'）。

Here it is my package.json

这是我的package.json

{
  "name": "ethereum",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "dependencies": {
    "ethereumjs-testrpc": "^4.0.1",
    "solc": "^0.4.13",
    "web3": "^1.0.0-beta2"
  },
  "devDependencies": {},
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC"
}

Any Idea? Am i doing something wrong?

任何想法？难道我做错了什么？

The problem comes from using a beta version of web3 its not stable at the moment and currently is under heavy development you have one of two options,

问题来自于使用测试版的web3，目前还不稳定，目前正处于大量开发阶段，你有两种选择之一，

either use a stable version 0.23 i think or something like that

使用稳定版本0.23我认为或类似的东西
or manually install all the needed dependencies i don't recommend this solution for a stable dapp since things are currently really unstable

或者手动安装所有需要的依赖项我不推荐这个解决方案用于稳定的dapp，因为事情目前非常不稳定

I solved it by removing node_modules folder, running npm install again and installing web3js manually in addition to package.json listing:

我通过删除node_modules文件夹，再次运行npm install并手动安装web3js以及package.json列表解决了这个问题：

Add dependency to package.json

向package.json添加依赖项

"web3": "^1.0.0-beta.31"

Rebuild modules

重建模块

rm -rf node_modules
npm install

Install web3 manually

手动安装web3

npm install web3@1.0.0-beta.31

I was facing this exact issue with: web3@1.0.0-beta.26

我正面对这个问题：web3@1.0.0-beta.26

I have fixed this issue by upgrading node from v6.11.3 to v8.9.4.

我已通过将节点从v6.11.3升级到v8.9.4来解决此问题。

I have removed node_modules folder and run: npm install to rebuild modules.

I think that web3 is using features that are only supported by node version 8.x.x.

Installing git on my Windows 10 machine helped. Dependencies did not install properly without it. https://git-scm.com/downloads

在我的Windows 10机器上安装git有帮助。没有它，依赖关系没有正确安装。 https://git-scm.com/downloads
