配置weex开发环境时候，首先要进行安装，执行如下命令：

npm install -g weex-toolkit@beta

 安装完以后，执行命令：weex help 一直提示错误： Error: Cannot find module 'async'

Error: Cannot find module 'async'

 然后使用npm install -g async 安装完以后，仍然出现该错误。尝试更新node版本和npm版本，仍然出错。

无论使用npm还是cnpm安装async模块，怎么安装都出错。

最后尝试使用weex安装，即执行命令：

weex install async

 成功：

C:\Users\Administrator\Desktop\tees>weex install async
√ Installed 1 packages
√ Linked 1 latest versions
√ Run 0 scripts
√ All packages installed (2 packages installed from npm registry, used 3s(network 3s), speed 155.12kB/s, json 2(14.08kB), tarball 418.85kB)

Start checking package, please wait ...

The module async was not suitable for the weex core
Please check the spelling

 再运行weex help命令，成功。

运行weex create project， 创建项目 成功。

C:\Users\Administrator\Desktop\tees>weex create testPro
√ Installed 1 packages
√ Linked 0 latest versions
√ Run 0 scripts
√ All packages installed (used 165ms(network 146ms), speed 16.11kB/s, json 1(2.35kB), tarball 0B)

后面只需要进行一系列的创建项目设置选项：

最后npm start 运行起来如图：

 最后就成功了产生了如下图页面：成功跑起来了，下载APP扫码即可查看效果。
