Mac os x yosemite安装appium 1.2.4及运行sample成功遇到的问题

原先使用appium正常，昨天升级了mac os x yosemite系统后，启动appium，可以看到1.1.0的版本号；但是 启动appium－doctor时提示

Running iOS Checks

✖ Could not detect Mac OS X Version

Appium-Doctor detected problems. Please fix and rerun Appium-Doctor.

而且编译并运行示例中的simple程序，编译并运行后出现失败

经过google后发现是xcode6及ios8的环境变量问题
解决方法：

所以只能重装appium了

在安装的过程中遇到以下几个问题：
1.安装appium，当前通过npm install appium
1）方法一：直接敲入命令
npm install －g appium
加载一段时间后弹出错误提示：

经过google，这个问题是因为校验和不对. 下的文件跟服务器上的文件校验和不相等. 应该是传输过程中下载的东西受损了.. 可能是网络原因.
所以该方法暂时不用
2）方法二：npm在下载appium时特别慢，经过google，觉得换registry可能有用；
官方默认的： https://registry.npmjs.org/appium
网上找的一个：http://registry.cnpmjs.org

敲入命令：npm --registry http://registry.cnpmjs.org install -g appium

下载过程中会出现错误

①在sudo下运行，

sudo npm --registry http://registry.cnpmjs.org install -g appium 【本人用这个命令安装成功】



运行完会出现提示

error: Appium will not work if used or installed with sudo. Please rerun/install as a non-root user. If you had to install Appium using
`sudo npm install -g appium`, the solution is to reinstall Node using a method (Homebrew, for example) that doesn't require sudo to install global npm packages.

权限问题,无法使用sudo来运行appium

尝试如下方法：

②解决方法如下：在运行node install appium前运行以下命令
>> cd /usr/local/bin

>> sudo chown -R root:admin /usr/local;
③然后卸载appium,卸载成功
npm uninstall appium -g
④最后再次下载，npm --registry http://registry.cnpmjs.org install -g appium
还是运行错误

错误原因：卸载不干净，清除/usr/local/lib/node_modules/下appium文件夹
sudo rm -rf appium

⑤再次运行npm install －g appium
下载成功，运行appium

info: Welcome to Appium v1.2.4 (REV 71584425ecf777349e3215f0f18e71e7782acfb6)
info: Appium REST http interface listener started on 0.0.0.0:4723
info: Console LogLevel: debug

3）继续npm install wd

npm --registry http://registry.cnpmjs.org install -g wd
安装完后验证appium能否运行
浏览器敲入http://0.0.0.0:4723/
显示：

That URL did not map to a valid JSONWP resource

说明成功

4）安装selenium组件

因为是Python版，所以就去Selenium官网下载Python的WebDriver（selenium-2.43.0.tar.gz）

https://pypi.python.org/pypi/selenium

解压：

#gzip -dc selenium-2.43.0.tar.gz | tar xvf -

安装：

#cd selenium-2.43.0

#sudo python setup.py install

安装完成selenium
5）执行sample code
下载源代码：git
clone https://github.com/appium/appium.git，下载完执行以下命令： ①　安装待测试的app

首先，我们需要用xcode编译这个app

#cd appium

#cd sample-code/apps/TestApp
#xcodebuild
-sdk iphonesimulator　
出现build successful表示OK
②执行测试脚本

#cd appium

#cd sample-code

#cd examples/python

#python simple.py
