Command For pip and Conda

pip

Full pip documentation refer here.

Install pip

Python version 3.4 and above has ensurepip module as a standard library which will install pip automatically. For cases where pip is not installed, refer here for the installation information.

Check pip version

$ pip --version
# or
$ python -m pip --version
pip 22.3.1 from C:...\Python39\site-packages\pip (python 3.9)

If the installed python earliest version is 3 above, using python or python3 has no difference.

Upgrade pip version

$ pip install --upgrade pip
# or
$ python -m pip install --upgrade pip
Requirement already satisfied: pip in c:...\python39\site-packages (22.3.1)

pip install package

Refer here for options available and examples:

```bash
$ pip install numpy
# or 
python -m pip install numpy
Collecting numpy
Downloading numpy-1.23.5-cp39-cp39-win_amd64.whl (14.7 MB)
...
Successfully installed numpy-1.23.5
```

pip to list the installed packages

$ pip list
# or
$ python -m pip list
Package                           Version
--------------------------------- -----------
analytics-python                  1.4.0

...
zipp                              3.8.0

There are options to list outdated package python -m pip list --outdated, list packages that are not dependencies of other packages python -m pip list --not-required and more, refer here for all the options and examples.

List installed packages for requirements file (requirements.txt) using pip

Use pip freeze -l or pip freeze --local for exporting only local installed packages and pip freeze --all to include setuptools, distribute, wheel and pip.

Refer here for all options available and examples.

This method only lists the packages, it does not create requirements text file (requirements.txt):

$ pip freeze
# or 
$ python -m  pip freeze
analytics-python==1.4.0
anyio==3.6.1
argon2-cffi==21.3.0
...
XlsxWriter==3.0.2
zipp==3.8.0

To create requirements text file (requirements.txt):

$ pip freeze > requirements.txt
# or 
$ python -m  pip freeze > requirements.txt
NO OUTPUT

The requirements.txt file will be created and save in the currently working directory (folder).

To install the package from requirements.txt

Steps:

  1. Change directory to the directory (folder) where the requirements.txt file is stored, in this use case the file is store in project_webapp directory (folder):

    $ cd virtual_env/project_webapp/
NO OUTPUT

    The prompt will change to from [wmxpg] ~ to [wmxpg] ~/virtual_env/project_webapp

  2. Install the requirements.
    -r= --requirement:

    $ pip install -r requirements.txt
Collecting numpy==1.23.5
Downloading numpy-1.23.5-cp311-cp311-win_amd64.whl (14.6 MB)
...
Successfully installed numpy-1.23.5

  3. Check the package has been installed:

    $ pip list
Package    Version
---------- -------
numpy      1.23.5
pip        22.1.2
setuptools 62.6.0
wheel      0.37.1

How do I Update PIP to Latest Version & Check if PIP Package is Installed - https://linuxhint.com/check-update-pip-latest-version/

The PIP is a cross-platform, written in Python to install and manage Python packages from the Python Package Index and from additional libraries (local and remote) that are not part of standard repositories.

How do I Update PIP to Latest Version To upgrade the PIP package, the command is quite simple. Type the following command in the terminal: pip install --upgrade pip

How do you check if a PIP Package is Installed To check if pip is already available on the system, the simplest way is to use the version option, and it will show the current version of the PIP package. So, open the terminal and type: pip --version

There are two approaches to check the installed PIP modules: Through the “pip list” command Through the “pip freeze” command

Check what PIP modules are Installed through the “PIP list” Command The list option will display the list of all the installed modules, including their versions on the system: pip list

Check what PIP modules are Installed through the “PIP freeze” Command The “PIP freeze” command is another way to find how many modules have been installed using the PIP package. To get it, type: pip freeze

How to update PIP Modules

Steps:

  1. To update all the PIP modules, firstly redirect all the modules name to a text file using the “Freeze” command:

    $ pip freeze > pip_modules.txt
TODO: NO EXAMPLE AT THE MOMENT

  2. Run the following command to update all of them:

    $ pip install –r pip_modules.txt --upgrade

Check pip version

$ pip list | grep mkdocs
# or 
$ pip list | findstr mkdocs
mkdocs                            1.4.2

Check specific library version

$ pip --version
# or
$ pip3 --version
pip 22.3.1 from C:\...local-packages\Python39\site-packages\pip (python 3.9)
