以太坊的合约是通过特殊的 solidity 语言开发，solidity 是通过 remix 编译器开发，网上很多的文章都太老，或者是相互抄袭的，导致我在使用过程中各种报错，估计现在都已经 2021 年了吧。

错误方式

• 安装 npm install remix-ide -g
• 运行 remix-ide

internal/modules/cjs/loader.js:883
  throw err;
  ^

Error: Cannot find module 'remixd'

这里肯定会报错，找不到 remixd 模块。

• 那就 npm install -g remixd

这里一定还是会报错，于是我查看了npmjs.com 查了一下，remix 包已经移动到 @remix-project/remixd 下面

• 所以 npm uninstall -g remixd 卸载老版本
• 继续安装新版本 npm install -g @remix-project/remixd

这里成功了，但是 remix-ide还是依然会报错，算了不想折腾这种方式了，还是使用 docker 吧

正确方式✅

• docker run -p 18080:80 -d --name remix remixproject/remix-ide:latest
  但是这里有个问题，是不能做文件映射，不能将宿主机和容器路径相关联，算了，先这样测试开发吧，后面再说。
