? ? Remix是一個用于開發和部署Solidity合約的線上IDE，該IDE含有各個版本的Solidity，當一個工程有多個Solidity版本時，就需要使用Remix來進行分開編譯和部署。

1、安裝相關的編譯與部署插件

1.1）安裝Solidity編譯插件

? ? 點擊Remix左側頁邊欄里的兩腳插頭圖標，進入Remix的搜索欄，輸入solidity關鍵字，按[Active]依次激活如下插件
? ? SOLIDITY COMPILER
? ? SOLIDITY STATIC ANALYSYS
? ? SOLIDITY UINT TESTING

1.2）安裝Solidity部署插件

? ? 點擊Remix左側頁邊欄里的兩腳插頭圖標，進入Remix是搜索欄，輸入run關鍵字，點擊[Active]即可安裝

1.3）安裝Debug插件和SOURCIFY代碼檢查插件

? ? 同樣，進入Remix是搜索欄，輸入Debug關鍵字，點擊[Active]即可安裝;
? ? 輸入SOURCIFY關鍵字，點擊[Active]即可安裝;
? ? 最后，一共6個插件，如下：

2、設置Remix的頁面顏色

? ? 點頁面左下角的齒輪按鈕 -->Themes --> 顏色如下：
? ? ? Dark(dark) 深藍色
? ? ? Light(ligt) 白色
? ? ? Midcentury(light) 淺棕色
? ? ? Black(dark) 深黑色
? ? ? Candy(light) 糖果色
? ? ? Cerulen(light) 淺青色
? ? ? Flaty(light) 淡白色
? ? ? Spacelab(ligth) 蛋白色
? ? ? Cybory (dark) 亮黑色
? ? 建議選擇第四個Black(dark)，如圖(2)所示：

3、新建一個Solidity文件，名稱為HelloWorldToken.sol

//HelloWorldToken.sol

4、設置編譯選項

? ? COMPILER: 0.4.26
? ? EVM VERSION: compiler default
? ? COMPILER CONFIGRURATION:
? ? ? √ Auto compile
? ? ? √ Enable optimization
? ? 點擊Compile按鈕，如圖(3)所示：

圖(3) 設置編譯選項

5、設置部署選項

? ? ENVIRIONMENT: JavaScript VM
? ? ACCOUTNT: 默認即可
? ? GAS LIMIT: 3000000
? ? VALUE: 0 wei
? ? CONTRACT: HelloWorldToken - browser/HelloWorldToken.sol
? ? 點擊[Deploy]按鈕，即可部署，如圖(4)所示：

圖(4)設置部署選項

? ? 等約半分鐘，部署完成后，左側Deploy Contracts下會彈出HelloWorldToken這一欄，點它的頭部，會展開列出里面的操作方法，點它右括號后的尾巴會復制該Token地址，如圖(5)所示：

圖(5) 點頭部查看函數列表， 點右括號的尾巴得到合約地址

6、驗證部署

? ? 點擊[name] 按鈕，得到Token的全稱；
? ? 點擊[owner]按鈕，得到Token的主人地址；
? ? 點擊[symbol]按鈕，得到Token的簡稱；
? ? 點擊[totalSupply]按鈕，得到Token的總量。
? ? 如圖(6)所示：

? ? 點擊[name]按鈕，得到Token的全稱為"HelloWorldToken"，與代碼里保持一致，這說明HelloWorldToken部署成功，它部署在本地JavaScript虛擬機里。 如果想要部署在測試網上，需要將部署選項參數ENVIRIONMENT設置為Injected Web3，并連上對應的MetaMask賬戶。
