这是一个系列文章，完整的合集链接：Appium 开发环境搭建合集

2015/2/25 update:
由于 testerhome/appium 已更新到最新版本，故把 更新代码库部分移到 Q&A 中。

2015/2/24 update:
把标题改为 Appium 开发环境搭建（1）-- 配置源码运行环境，同时微调了格式，以配合后续文章。

之前加入了 doctorq 的开源项目，今天提前配置一下 testerhome/appium 的源码运行环境。过程中发现有一些地方官方文档没有提到，在此分享一下配置过程。
PS：这是我的第一个贴子，有些地方写得不对或不够清晰请跟贴说明，我会立即更正。

1. 下载代码库

git clone https://github.com/testerhome/appium.git

然后运行此命令时所在的目录会出现一个appium文件夹。进入文件夹：

cd appium

3. 根据官方介绍配置从源码运行 appium 的环境（ios, android, seledroid）

参考资料：https://github.com/appium/appium/blob/master/docs/en/contributing-to-appium/appium-from-source.md
注意：我的配置环境为 Mac OS X 10.10.1。根据官方要求，配置过程中除非官方说明，否则尽量不要使用sudo命令。这里遇到的错误基本都和系统当前配置有关。可能有些人会遇到，有些人不会，请大家按照需要参考。

3.1 运行appium目录下的reset.sh 进行环境配置。

这个脚本进行了各个主要运行环境（ios, android, selendroid）的重置和更新，例如下载需要用到的 npm 包、安装 selendroid 等。
如果运行出错就加上--verbose参数再跑，看是哪里出错。

运行过程中我出现了几次错误，我把我遇到的错误信息和解决方案放在了文章末尾。大家可以参考一下（这里的信息都是用了--verbose后才会显示的）.
另外，appium 官方有个地方也有说明其他常见错误及解决方案：https://github.com/appium/appium/blob/3f0aee727bd320377b63bbc57ab4b3fb591260c4/docs/en/appium-setup/troubleshooting.md。
如果用上面的办法还是解决不了，可以去 github报个 issue来让 appium 团队帮忙寻找解决方案。

3.2（仅针对 ios）运行sudo ./bin/authorize-ios.js配置 ios 的认证环境（用来让 ios 不认为 appium 安装的应用有安全问题）。

$ sudo ./bin/authorize-ios.js
Password:
Enabling DevToolsSecurity
Updating security db for developer access
Granting access to built-in simulator apps
Authorization successful

3.3 使用node .运行 appium server：

$ node .
info: Welcome to Appium v1.3.5 (REV 80453f682c18c32377bdf5664533e4df69a62770)
info: Appium REST http interface listener started on 0.0.0.0:4723
info: Console LogLevel: debug

至此，从源码运行 appium 的环境完成了。此时运行的 appium 就是从源码运行的了。如果是 debug 的话，这样基本足够了。但对于开发来说，但这只是配置开发环境的第一步（官方文档里的Setting up Appium from Source部分），后面还有Hacking on Appium，Hacking with Appium for iOS, Hacking with Appium for Android来配置开发环境，以及Running Tests， Running individual tests来执行测试。后面我会根据官方文档（https://github.com/appium/appium/blob/master/docs/en/contributing-to-appium/appium-from-source.md）配置下去，如果有遇到官方文档内没有提到的问题，我会另外开贴来帮助大家处理这些问题。

Q&A

更新代码库

通过 Fork 出来的代码库都有可能存在和源代码库不一致的情况。在此简述一下如何更新代码库。

注意：这里的同步仅仅更新了你的本地代码库，github 上的代码库还是旧的。需要使用git push命令才会把这个变更更新到远程代码库里。

**原因分析：**之前用管理员权限安装过npm，或者某些npm包用了管理员权限来安装。这里千万不要参照错误提示用管理员执行，否则appium就装不下去了。
**解决方案：**
卸载npm，删除`~/.npm`文件夹（部分目录没权限就用`sudo`来删），然后用`brew install npm`重新安装。安装后再运行`./reset.sh --verbose`（`brew`命令是`homebrew`的命令，提示没找到命令的请安装[homebrew]。不能用node官方安装程序来装）

**原因分析**：没找到mvn命令。我没有装`maven`。
**解决方案**：参考下一个问题，使用以下命令安装`maven`

brew install homebrew/versions/maven31
sudo ln -s /usr/local/Cellar/maven31/3.1.1 /usr/local/Cellar/maven/
brew switch maven 3.1.1

**原因分析**：这是安装Selendroid时出错了，错误信息表示是找不到class的声明。这个只能求助google了。
**解决方案**：google后找到<https://github.com/appium/appium/issues/4490>，根据里面的解决方案使用下面命令修复：

brew install homebrew/versions/maven31
sudo ln -s /usr/local/Cellar/maven31/3.1.1 /usr/local/Cellar/maven/
brew switch maven 3.1.1

**原因分析**：大致意思是没有找到Android sdk里的`Platform/API level 16`。官方文档提到配置seledroid的话需要用到level 16的API。
**解决方案**：装上level 16的API。

**原因分析**：这个原因应该是编译器暂存空间不足导致的（StackOverflowError）。
**解决方案**：运行下面的命令加大暂存空间：

export MAVEN_OPTS="-Xms1024m -Xmx2048m -Xss2048k"
