react 项目创建 （umi）踩坑

今天要新建一个react 项目完成一个demo 这回我们用dva + umi 来写

所以我们需要用umi.js 来创建一个项目

npm create umi

这里的选择可是一个大坑

最开始是这样的，我们要创建一个app的项目 按 ↑↓都没有用 ，无法实现选择。我们需要在cmd 或者 gitbash 等终端手动把这个箭头更改到 app 的位置

包括之后的 选择 ts 和 js 也需要这么修改

? Select the boilerplate type (Use arrow keys)
❯ ant-design-pro  - Create project with an layout-only ant-design-pro boilerplate, use together with umi block.
  app             - Create project with a simple boilerplate, support typescript.
  block           - Create a umi block.
  library         - Create a library with umi.
  plugin          - Create a umi plugin.

这样选择成功后 我们创建的项目就是这个样子的。

Did you mean this?
    repo

? Select the boilerplate type block
? What's the block name? (project)
                                  demo
? What's the block name? demo
? What's your block description?

? What's your email?
? What's your name? Create a umi block.
? What's your name?
? Which repo is your block stored under github? (umijs/umi-blocks)
? Which repo is your block stored under github? umijs/umi-blocks

   create package.json
   create .gitignore
   create .prettierignore
   create .prettierrc
   create .umirc.js
   create LICENSE
   create README.md
   create src\index.css
   create src\index.js
✨ File Generate Done

此时我们就可以 安装依赖

npm i

然后可以启动项目

npm start
