install robotframework (linux)

1. Ubuntu自带的Python没有pip, 所以首先安装pip
    sudo apt-get install python-pip
2. 安装robotframework
    sudo pip install robotframework
   
    # Upgrade to the latest version
       sudo pip install --upgrade robotframework

    # Install a specific version
       sudo pip install robotframework==2.8.5

    # Uninstall
       sudo pip uninstall robotframework

3. 检测是否安装成功:
    $ pybot --version
      Robot Framework 2.8.7 (Python 2.7.8 on linux2)

4. 给robotframework安装库. 因为我主要想用robot做interface测试, 所有安装了http library
   sudo pip install --upgrade robotframework-httplibrary
   sudo pip install -U robotframework-requests
现在就可以写testcase 进行测试了......
