安装robotframework -ride

Question

我是Python的新手，一直在尝试使用pip安装一些软件包。

我已经经历了这个顺序-------------

从以下位置下载Python 2.7.15

https://www.python.org/downloads/

PATH = C:C:\Python27;C:\Python27\Scripts 
(Is this we have to set in User Variable or System Variable?)

然后从此链接下载wxPython（下载此版本wxPython2.8-win64-unicode-2.8.12.1-py27）

http://sourceforge.net/projects/wxpython/files/wxPython/2.8.12.1/

然后

从Python下载用于Python的setuptools（setuptools-39.2.0.zip）

https://pypi.org/project/setuptools/#files

然后

从以下位置下载PIP文件（pip-10.0.1.tar.gz）

https://pypi.org/project/pip/#files

现在提取Setuptools

从同一文件夹TYPE“ cmd”提取后，它将打开然后运行此命令

"python setup.py install"

现在提取PIP文件

从同一文件夹TYPE“ cmd”提取后，它将打开然后运行此命令

"pip install robotframework"

在cmd上运行，这些命令得到一对一的赞扬

pip install robotframework-ride
pip install robotframework-selenium2library
pip install selenium
pip install decorator
pip install docutils
pip install xlrd
pip install xlwt
pip install xlutils
pip install pigments

但是pip安装robotframework-ride展开会给我

D:\Python\pip-10.0.1\pip-10.0.1>pip install robotframework-ride
Collecting robotframework-ride

Complete output from command python setup.py egg_info:

 ork-ride\setup.py", line 20, in <module>
    execfile(join(ROOT_DIR, 'src', 'robotide', 'version.py'))

 ----------------------------------------
  Command "python setup.py egg_info" failed with error code 1 in C:\Users\Deeksha\
  AppData\Local\Temp\pip-install-f5wsnk57\robotframework-ride\

我该如何解决？
