1. 先安裝 pip

download pip-6.0.8.zip from https://github.com/pypa/pip/releases  to a dir for example(C:\Python27\download)

unzip it and cd the dir(C:\Python27\download\pip-6.0.8)

python setup.py install

C:\>cdC:\Python27\download\pip-6.0.8

C:\Python27\download\pip-6.0.8> python setup.py install

2. 

cd c:\Python27\Scripts    (python本機的安裝路徑c:\Python27)

c:\Python27\Scripts>pip install robotframework-sshlibrary

3. 認真看下，Notice that on Windows you should still install PyCrypto manually first.  on

下載下來，先安裝這個exe

然後：重新執行

cd c:\Python27\Scripts    (python本機的安裝路徑c:\Python27)

c:\Python27\Scripts>pip install robotframework-sshlibrary
