前提条件：安装nodejs。需要用到npm和cnpm
可在终端中查看node版本：

C:\Users\璐从今夜白。>node -v
v12.18.3

安装步骤如下：
第一步：命令行安装REMIX IDE
CTRL+R调出WINDOWS命令行窗口，输入以下命令安装remix-ide本地环境。

npm install remix-ide -g

安装成功结果输出如下：

npm WARN deprecated circular-json@0.3.3: CircularJSON is in maintenance only, flatted is its successor.
C:\Users\璐从今夜白。\AppData\Roaming\npm\remix-ide -> C:\Users\璐从今夜白。\AppData\Roaming\npm\node_modules\remix-ide\bin\remix-ide
+ remix-ide@0.10.3
added 177 packages from 188 contributors in 42.411s

第二步：启动本地IDE
在WINDOWS CMD中输入REMIX-IDE启动程序：

D:\remix>remix-ide

正常返回应该是：

Starting Remix IDE at http://localhost:8080 and sharing D:\remix

但我在执行报错遇到问题如下：

internal/modules/cjs/loader.js:968
  throw err;
  ^

Error: Cannot find module 'remixd'

  ]
}

解决方式： 在报错路径中 \AppData\Roaming\npm\node_modules\remix-ide\bin\remix-ide下，去删除remixd相关内容

去除之前,如下：
#!/usr/bin/env node
var path = require(‘path’)
var httpServer = require(‘http-server’)
var remixd = require(‘remixd’)
var server = httpServer.createServer({
root: path.join(__dirname, ‘/…/’)
})
var folder = process.argv.length > 2 ? process.argv[2] : process.cwd()
server.listen(8080, ‘127.0.0.1’, function () {})
var router = new remixd.Router(65520, remixd.services.sharedFolder, { remixIdeUrl: ‘http://localhost:8080’ }, (webSocket) => {
remixd.services.sharedFolder.setWebSocket(webSocket)
remixd.services.sharedFolder.setupNotifications(folder)
remixd.services.sharedFolder.sharedFolder(folder, false)
})
router.start()
console.log(’\x1b[33m%s\x1b[0m’, 'Starting Remix IDE at http://localhost:8080 and sharing ’ + folder)

去除之后如下：
#!/usr/bin/env node
var path = require(‘path’)
var httpServer = require(‘http-server’)
var server = httpServer.createServer({
root: path.join(__dirname, ‘/…/’)
})
var folder = process.argv.length > 2 ? process.argv[2] : process.cwd()
server.listen(8080, ‘127.0.0.1’, function () {})
console.log(’\x1b[33m%s\x1b[0m’, 'Starting Remix IDE at http://localhost:8080 and sharing ’ + folder)

启动成功后，输入 localhost:8080不行的话，可以考虑加个路径/index ,即：localhost:8080/index,就可以啦
