看起来好像是 example 下的 package.json 里面缺少 name 字段。
https://github.com/ykfe/imove/blob/master/example/package.json

是不是应该改成这样，增加一个 name: example 为 package name。

    "start": "umi dev",

    "postinstall": "umi generate tmp"

大概看了一下，应该就是执行 lerna bootstrap 的时候调用 npm-lifecycle 来执行 example 包的postinstall 命令时报错了，因为 example 包缺少 name 字段。

@zhangxh1023 不用执行 lerna bootstrap，如果要跑 example 的话，按以下步骤操作：

$ git clone https://github.com/ykfe/imove.git
$ cd imove/example
$ npm install
$ npm start

不要在根目录 npm install

好的吧，是我看错了。了解了 :)
