下载源码

官网下载源码地址：

https://github.com/vuejs/vue-next

有git的可以克隆：git clone https://github.com/vuejs/vue-next.git

没有git的直接下载源码

运行源码

使用如下命令在cmd中执行，前提是先安装Node.js

# 如果没有安装yarn的需要安装一下
npm install -g yarn --registry=https://registry.npm.taobao.org

# 还可以设置一下yarn的国内镜像
yarn config set registry https://registry.npm.taobao.org -g
yarn config set sass_binary_site http://cdn.npm.taobao.org/dist/node-sass -g

# 安装依赖
yarn

# 运行
yarn run dev

运行源码报错

运行出现如下错误：

yarn dev
yarn run v1.22.10
$ node scripts/dev.js

C:\Users\star\Documents\project\vue-next-master>git rev-parse HEAD
fatal: ambiguous argument 'HEAD': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'
HEAD

看原因是因为git仓库获取不到head信息，所有就初始化仓库并提交到本地仓库中

# 运行源码需要Git仓库
git init
git add .
git commit "初始化项目"

# 如果没有安装yarn的需要安装一下
npm install -g yarn --registry=https://registry.npm.taobao.org

# 还可以设置一下yarn的国内镜像
yarn config set registry https://registry.npm.taobao.org -g
yarn config set sass_binary_site http://cdn.npm.taobao.org/dist/node-sass -g

# 安装依赖
yarn

# 运行
yarn run dev

成功运行

这时候运行就成功了，运行成功出现如下信息：

rollup v2.38.5
bundles C:\Users\star\Documents\project\vue-next-master\packages\vue\src\index.ts → packages\vue\dist\vue.global.js...
