For New versions

Older versions of python may not have pip installed and get-pip will throw errors. Please update your python (2.7.15 as of Aug 12, 2018).

All current versions have an option to install pip and add it to the path.

Steps:

1. Open Powershell as admin. (win+x then a)
2. Type python -m pip install <package>.

If python is not in PATH, it'll throw an error saying unrecognized cmd. To fix, simply add it to the path as mentioned below.

[OLD Answer]

Python 2.7 must be having pip pre-installed.

Try installing your package by:

1. Open cmd as admin. (win+x then a)
2. Go to scripts folder: C:\Python27\Scripts
3. Type pip install "package name".

Note: Else reinstall python: https://www.python.org/downloads/

Also note: You must be in C:\Python27\Scripts in order to use pip command, Else add it to your path by typing: [Environment]::SetEnvironmentVariable("Path","$env:Path;C:\Python27\;C:\Python27\Scripts\", "User")

Download pip script from https://bootstrap.pypa.io/get-pip.py and then run using python as:-

python get-pip.py

or you can use python to install modules directly

python -m pip install <module>

This is one way of installing pip on a Windows system.

1. Download the "get-pip" python script from here: https://bootstrap.pypa.io/get-pip.py

2. Save the file as getpip.py

3. Run it from cmd: python getpip.py install

I've seen this issue before with 2.7.14. Fixed it by :

1. Re-install python 2.7.14
2. During the installation, select default path and put a check mark in the installation options to add python to windows path i.e. environmental variables.
3. After installation is complete, go to System from the Control Panel, select Advanced system settings, and clicking Environment Variables.
4. Verify that the system variable "path" has "C:\Python\;C:\Python\Scripts;" added to the list.

5. In cmd, run "where python" and then "where pip". Which will show for example:

   λ where python
   C:\Python\python.exe
   
   λ where pip
   C:\Python\Scripts\pip.exe
   

6. Run pip, then it should show different pip run command options.

回答5:

It is possible that in python 2.7 pip is installed by default. if it is not then you can execute

python -m ensurepip --default-pip

This worked for me.

Add the following to you environment variable PATH.

C:\Python27\Scripts

This path will contain the pip executable file. Make sure it exist. If it doesn't then you'll need to install it using the get-pip.py script.

Additonally, you can read the following link to get a better understanding.

回答7:

pip is installed by default when we install Python in windows. After setting up the environment variables path for python executables, we can run python interpreter from the command line on windows CMD After that, we can directly use the python command with pip option to install further packages as following:-

C:\ python -m pip install python_module_name

This will install the module using pip.

you have to first download the get-pip.py and then run the command :

python get-pip.py
