如下圖所示，在瀏覽器直接打開，，在chrome中測試上面的代碼，控制臺會報如下錯誤：
d3.v4.min.js:2 Access to XMLHttpRequest at 'file:///C:/Users/volod/Desktop/D3.js%E5%8A%A0%E8%BD%BDcsv%E6%95%B0%E6%8D%AE/nemployment.tsv' from origin 'null' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https.
這是因為安全機制禁止了cross origin request，不允許直接讀取本地文件, 所以我們需要一個webserver來server我們的數據
2. VS Code在本地進行調試和打開本地服務器
<1>在擴展中搜索插件?Debugger for Chrome 進行安裝。
<2>配置launch.json文件，根據步驟來。file就是你在瀏覽器中需要運行的文件的路徑。
{// 使用 IntelliSense 了解相關屬性。 // 懸停以查看現有屬性的描述。// 欲了解更多信息，請訪問: https://go.microsoft.com/fwlink/?linkid =830387"version": "0.2.0","configurations":

{ "type": "chrome","request": "launch","name": "Launch Chrome against localhost","url": "http://localhost:8080","webRoot": "${workspaceFolder}"
}]
} <3>配置好之后，直接使用調試是不行的，需要開啟服務器。
3.?npm install -g live-server 安裝，開啟服務器
（3與4都能實現VS Code在本地進行調試和打開本地服務器，選擇其中一種方法即可
1.打開vs code制臺。選擇終端，在終端里輸入??npm install -g live-server? 進行安裝.
npm install -g live-server
2.然后再輸入live-server,按下回車，如下圖所示：
4.在vs code中安裝live server 插件
（3與4都能實現VS Code在本地進行調試和 打開本地服務器，選擇其中一種方法即可
