STF环境问题篇（MAC）

安装教程可以参考我之前写的，这里不再多说，直接说问题。

安装完成后输入stf doctor查看工具依赖是否正确

问题1：Unexpected error checking ZeroMQ: Error: Module version mismatch. Expected 48, got 47.

问题分析：根据错误提示，初步定位node moudle的版本不一致，期望的是48，而我的node moudle 是47.于是进入node官网（https://nodejs.org/en/download/releases/）下载moudle 等于48的nodejs版本。

node moudle version 可以根据下图中红框一列来确定自己所需要的版本。

解决方法：将v5.x版本升级到v6.x后，再次运行stf doctor，该问题解决。又出现问题2。

ps:问题灵感源：https://github.com/nodejs/node/wiki/Breaking-changes-between-v6-and-v7

Native Modules (Addons)

• The Native Module version mismatch error has been updated to be far more clear.
  • Refs: [1fda657cac], #8391

Previously:

Module version mismatch. Expected 51, got 48.

Now:

The module '<module>'
was compiled against a different Node.js version using
NODE_MODULE_VERSION 48. This version of Node.js requires
NODE_MODULE_VERSION 51. Please try re-compiling or Re-installing
the module (for instance, using `npm rebuild` or `npm install`).

• The NODE_MODULE_VERSION is now 51.
  • Refs: [96933df2ff], #8808

问题2：Error: The module '/usr/local/lib/node_modules/stf/node_modules/_zmq@2.15.3@zmq/build/Release/zmq.node' was compiled against a different Node.js version using NODE_MODULE_VERSION 47. This version of Node.js requires NODE_MODULE_VERSION 57. Please try re-compiling or re-installing the module

问题分析：在GitHub上看到外国友人这么说的：

大概是说在安装某个依赖应用中，我们升级或者安装了其他版本的node版本导致安装应用时所使用node版本与我们变更后当前的node版本不一致。

解决方法：根据错误提示建议，及国外友人建议，执行npm install 或 npm rebuild去重新构建node，注意：执行npm install / npm rebuild命令必须进入stf根目录执行

问题3：

scripts.prepublish: "bower install --allow-root && not-in-install && gulp build || in-install"
(node:1305) fs: re-evaluating native module sources is not supported. If you are using the graceful-fs module, please update it to a more recent version.

解决方法：参考 https://toutiao.io/posts/9kf4j3/preview 方可解决

问题4：插入手机后，STF显示手机信息但一直处于disconnect状态，刷新页面后，手机设备信息全部消失。查看stf控制台输出，如下：

FTL/util:lifecycle 7678 [5e56e8f2] Shutting down due to fatal error
INF/provider 6994 [*] Cleaning up device worker "5e56e8f2"
ERR/provider 6994 [*] Device worker "5e56e8f2" died with code 1

npm ERR! jpeg-turbo@0.4.0 install: node-pre-gyp install --fallback-to-build
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the jpeg-turbo@0.4.0 install script 'node-pre-gyp install --fallback-to-build'.

解决方法：

1、install yams, run brew install yasm 

2、At last run cnpm install -g stf
