纯粹问题流水，勿喷！^_^

1.问题：

升级node v8.2.1,npm 5.3.0后antd-adimin下npm install报错

antd-admin git:(master) ✗ npm installnpm WARN checkPermissions Missing write access to /home/quanpower/antd-admin/node_modules/_read-pkg-up@2.0.0@read-pkg-up/node_modules/find-upnpm ERR! path /home/quanpower/antd-admin/node_modules/_read-pkg-up@2.0.0@read-pkg-up/node_modules/find-upnpm ERR! code ENOENTnpm ERR! errno -2npm ERR! syscall accessnpm ERR! enoent ENOENT: no such file or directory, access '/home/quanpower/antd-admin/node_modules/_read-pkg-up@2.0.0@read-pkg-up/node_modules/find-up'npm ERR! enoent This is related to npm not being able to find a file.npm ERR! enoent npm ERR!

Google试了若干办法都没搞定，也看到好多人说npm 5会出这问题，有npm cache verify，npm cache clean -f,有说打开着IDE问题，也去github npm issue里看了下https://github.com/npm/npm/issues/17444，没找到根本答案，浪费了一天时间，最后还是rm -rf node-modules重新来过了。

结果出现checksum问题，后面又把package-lock.json干掉！终于可以继续调试了，问题症结不解。

2.dva

过了一遍大dva+antd crud的例子

3.推荐一个调试工具：Redux Devtools + react developertools配合使用，数据流十分清晰

4.利用git submodule将项目加到另外一个smart-iiot里面，另superset也考虑加
