Question

尝试使用docker-composer up命令设置锯齿形供应链，但是收到以下错误。在版本0.10.1的Windows 10笔记本电脑上运行。我已经从https://github.com/hyperledger/sawtooth-supply-chain下载了文件，并按照readme.md文件进行设置。

当我查找文件'/sawtooth-supply-chain/ledger_sync/index.js'时，我得到一个javascript语法错误，代码为800A03EA，Source为Microsoft JScript编译错误。有人可以帮忙吗？

/sawtooth-supply-chain/server/index.js中index.js中的代码如下：

const express = require('express')
const db = require('./db')
const blockchain = require('./blockchain')
const protos = require('./blockchain/protos')
const api = require('./api')
const config = require('./system/config')

const PORT = config.PORT
const app = express()

Promise.all([
  db.connect(),
  protos.compile(),
  blockchain.connect()

  .then(() => {
    app.use('/', api)
    app.listen(PORT, () => {

  })
  .catch(err => console.error(err.message))

我不知道上面的解决方案，但是如果您安装了VirtualBox之类的VM，然后在VirtualBox中使用Docker和docker-compose运行Sawtooth，将会发现它容易得多。

Answer 2

我今天也对此进行了搜索。 JScript / 基于Microsoft Windows的脚本宿主无法处理ECMAScript类型语法或Regex功能。

对我来说，我发现它可能只能使用诸如以下的关键字：

let。
forEach
exec

（最后两个带有正则表达式匹配器）。

顺便说一句：代码是以下内容的合并：

regex101为JavaScript生成的内容，以及
来自this之类的Wscript内容。

我最终放弃了JavaScript，转而使用VBScript，因为我试图为包含来自Automation Anywhere的多个组以及一次包含多个结果的正则表达式调用脚本代码。
