'easy_install' is not recognized as an in internal or external command, operable program or batch file

问题

I have just downloaded and installed the latest version of Python on my Windows 7 machine.

Python 2.7.3

Now I want to install a Twitter library I found online:

However when I try to run easy_install tweepy, I get this error message:

'easy_install' is not recognized as an in internal or external command, operable program or batch file.

Python has already been placed into my path, as I can invoke the Python program into the command line.

Here is a screenshot of my folder where Python is installed.

And inside the Tools folder:

And inside the scripts folder:

You need to:

1. Install easy_install: http://pypi.python.org/pypi/setuptools

2. Add C:\Python27\Scripts to your PATH

I had the same issue with Python 3.4. Fixed it with the steps below:

cd C:\Python34\Scripts .\easy_install pip

(or what you need to install) with the .\ you sort of grant admin permissions to the command

回答3:

I think that you should set the 'PATH' variable in order to execute it

回答4:

Looks like easy-install is not itself installed on your system.

See this previous question for instructions on installing.
