How do I install pip on Windows?
(40 answers)
Closed 6 years ago.
I have installed Python 3.4.1 in windows desktop, but i don't have pip. I am trying to install a module from https://www.reportlab.com/reportlabplus/installation/ it shows pip install rlextra -i https://www.reportlab.com/pypi/. And then if I execute the reported command, it shows the following
C:\Python34>pip install rlextra -i https://www.reportlab.com/pypi/
'pip' is not recognized as an internal or external command,
operable program or batch file.
Edit: This question is not about how to install pip, instead why you need pip ?
The pip command is a tool for installing and managing Python packages, such as
those found in the Python Package Index.
It's a replacement for easy_install.
https://github.com/pypa/pip
Using PIP, You can install the module. It will install the dependency also.
Pip is a package management system used to install and manage software packages written in Python.
You have to download PIP.then you can use pip to install packages.
download pip from here: https://pypi.python.org/pypi/pip
I can't add a comment, so take a look at this link
How do I install pip on Windows?
you can think of pip as a "package" manager, you use it to install certain libraries or packages to your python installation.

How to install packages offline?
(12 answers)
Closed 1 year ago.
I am currently using an offline Windows 10 environment and I need to use pip to install a package.
The traditional pip install "myPackage.tar.gz" is not working because pip makes a network request and fails because my machine has no internet.
With this in mind I tried the following command to ignore dependency checking. pip install myPackage.tar.gz -f./ --no-index –-no-deps. The command did install “Successfully ” but when I tried to use the package I got a ModuleNotFoundError.
My question is does pip work offline? If not what would be a work around?
Thank you,
Marco
Do you have those packages already downloaded in your computer?
If not, at some point you will need an internet connection.
There's pip download command which lets you download packages without installing them:
pip download -r requirements.txt
(In previous versions of pip, this was spelled pip install --download -r requirements.txt.)
When you have your packages downloaded, use pip install --no-index --find-links /path/to/download/dir/ -r requirements.txt to install what you have previously downloaded, without the need to access on internet

$ pip install Pillow
Error: 'pip' is not recognized as an internal or external command,
operable program or batch file.
I'm doing this in the command prompt on windows.
Official documentation for installing pip can be found here.
In short, you can download get-pip.py from here (right-click the link and then choose Save link as...). Then you can navigate in the command prompt to the directory you downloaded get-pip.py to.
Once you've done that, you can install pip for just your user with
python get-pip.py --user
If you want to install pip system-wide, you need to use an Administrator command prompt, and run
python get-pip.py
Then you can install Pillow with
python -m pip install Pillow
You need to install pip, to be able to download packages.
Installing pip
Pip is the package installer for Python and is required to install Python Packages.
If you are using Python 3.4 onwards, then pip should come pre-installed.
If you are using a version of Python 3 older than Python 3.4, then the official pip install instructions can be found here
Note: you can find out what version of Python you are running by typing python --version in the terminal
To check if pip is installed, run pip help in the terminal.
Installing the pillow package
Once you have pip installed, you can now install the pillow package. This is as simple as typing pip install pillow into your terminal.
Once you've done this, you will successfully have the pillow package installed for Python.
First run:
python
if it says that it can't recognize the command, it means you haven't installed python properly on your system. Install it using this guide
If python is installed, run this to install pip:
sudo apt-get install python-pip
Finally, try installing pillow again. It will probably work now.

bash: pip: command not found

It appears as though pip is installing fine (it says it "Successfully installed pip-19.1.1"), but I cannot located pip on my computer afterwards. I'm running OSX 10.14.4.
I haven't used Python recently on my Mac, and I recently upgraded to Python3 for a project, which requires me to use pip as well. I had pip already installed and working, but it kept trying to use Python 2.7, so I decided to uninstall and reinstall pip with the new version of Python. I've gone through a few tutorials to try and install pip. Most recently, I've tried the method recommended here: https://ahmadawais.com/install-pip-macos-os-x-python/, which has me run:
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python get-pip.py
This appears to work just fine:
Collecting pip
Downloading https://files.pythonhosted.org/packages/5c/e0/be401c003291b56efc55aeba6a80ab790d3d4cece2778288d65323009420/pip-19.1.1-py2.py3-none-any.whl (1.4MB)

Installing collected packages: pip
Found existing installation: pip 19.1.1
Uninstalling pip-19.1.1:
Successfully uninstalled pip-19.1.1
Successfully installed pip-19.1.1
However, attempting to use pip after this results in "command not found". I realize that the likely issue is that it's just not in my PATH, but I don't know how to locate it to add it to my path.
Please let me know if there's anything else that would be useful to diagnosing this. I'm pretty new to working with these tools, so I might just be missing something obvious.
You can either try:
pip3 install package-name
or you can add the locate the pip, and add if not already added into your path:
locate pip3
/usr/bin/pip3
/usr/bin/pip3.6
/usr/local/bin/pip3
/usr/local/bin/pip3.7
/usr/share/bash-completion/completions/pip3
/usr/share/bash-completion/completions/pip3.6
/usr/share/man/man1/pip3.1.gz
/usr/share/ruby/vendor_ruby/puppet/provider/package/pip3.rb
Then select the right one for your use. Generally for the fresh install (python 3), you should do (see this post):
pip3 install package-name
You can check the version using:
pip3 --version
Check this question if you have further issues.

How to install pip on python 3.6, not the default python 2.7?
(1 answer)
Closed 4 years ago.
Okay, so I have the following issue. I have a Mac, so the the default Python 2.7 is installed for the OS's use. However, I also have Python 3.6 installed, and I want to install a package using Pip that is only compatible with python version 3. How can I install a package with Python 3 and not 2?
To download use
pip3 install package
and to run the file
python3 file.py
Why do you ask such a thing here?
https://docs.python.org/3/using/mac.html
4.3. Installing Additional Python Packages
There are several methods to install additional Python packages:
Packages can be installed via the standard Python distutils mode (python setup.py install).
Many packages can also be installed via the setuptools extension or pip wrapper, see https://pip.pypa.io/.
https://pip.pypa.io/en/stable/user_guide/#installing-packages
Installing Packages
pip supports installing from PyPI, version control, local projects, and directly from distribution files.
The most common scenario is to install from PyPI using Requirement Specifiers
$ pip install SomePackage # latest version
$ pip install SomePackage==1.0.4 # specific version
$ pip install 'SomePackage>=1.0.4' # minimum version
For more information and examples, see the pip install reference.
Just a suggestion, before you run any command that you don't know what is it, please use which your_cmd or whereis your_cmd to find its path.

Dealing with multiple Python versions and PIP?
(28 answers)
Closed 1 year ago.
I'm trying do from Cython.Build import cythonize and I get the message ImportError: No module named 'Cython', but I instaled the Cython with the comand pip install Cython. What's wrong?
Python 3.5
Cython 0.25.2
Windows 8
just directly install from pypi:
pip install Cython
https://pypi.org/project/Cython/
Use Pip3 command:
pip3 install --upgrade cython
I reinstalled the Cython with conda and install the Microsoft Visual C++ Build Tools and it works fine.
The problem for me was the pip version. Running python -m pip install pip --upgrade solved the issue.
You can download the the newest Cython release from http://cython.org/ or you can directly download by clicking this link here Unpack the tarball or zip file, enter the directory, and then run:
python setup.py install
I personally ran into this problem when I was trying to set up a new virtual environment. I simply installed Cython with python -m pip install Cython and then proceeded to install all the rest of my stuff I needed with python -m pip install -r requirements.txt.
Once it was done, it actually uninstalled Cython for me...
Why? Heck do I know... I ain't that kind of expert :<
it should be path problem.
go to windows search for python idle
right click idle - open file location
where
right click on python.exe - open file location
if the module not in that location
type cmd and press enter in path
now install module with pip install cython
it will work fine
