使用remix发布部署 发币 智能合约


Remix是一个基于浏览器的编译器和IDE,使用户能够使用
Solidity语言构建以太坊合约并调试事务。

在上一篇文章已经成功的使用代码讲智能合约编译并且发布部署到了链上,可是在部署 发币的智能合约 不行,于是另找方法➡️remix

git clone https://github.com/ethereum/remix-ide.git

cd remix-ide

npm install   //可能会出错多试几次,网络问题。

sudo npm run setupremix  

npm run build

npm start

浏览器打开: http://127.0.0.1:8080
