How to install pip with Python 3?

Older version of Homebrew

If you are on macOS, use homebrew.

brew install python3 # this installs python only
brew postinstall python3 # this command installs pip

Also note that you should check the console if the install finished successfully. Sometimes it doesn't (e.g. an error due to ownership), but people simply overlook the log.

UPDATED - Homebrew version after 1.5

According to the official Homebrew page:

On 1st March 2018 the python formula will be upgraded to Python 3.x and a python@2 formula will be added for installing Python 2.7 (although this will be keg-only so neither python nor python2 will be added to the PATH by default without a manual brew link --force). We will maintain python2, python3 and python@3 aliases.

So to install Python 3, run the following command:

brew install python3

Then, the pip is installed automatically, and you can install any package by pip install <package>.

If your Linux distro came with Python already installed, you should be able to install PIP using your system’s package manager. This is preferable since system-installed versions of Python do not play nicely with the get-pip.py script used on Windows and Mac.

Advanced Package Tool (Python 2.x)

sudo apt-get install python-pip

Advanced Package Tool (Python 3.x)

sudo apt-get install python3-pip

pacman Package Manager (Python 2.x)

sudo pacman -S python2-pip

pacman Package Manager (Python 3.x)

sudo pacman -S python-pip

Yum Package Manager (Python 2.x)

sudo yum upgrade python-setuptools
sudo yum install python-pip python-wheel

Yum Package Manager (Python 3.x)

sudo yum install python3 python3-wheel

Dandified Yum (Python 2.x)

sudo dnf upgrade python-setuptools
sudo dnf install python-pip python-wheel

Dandified Yum (Python 3.x)

sudo dnf install python3 python3-wheel

Zypper Package Manager (Python 2.x)

sudo zypper install python-pip python-setuptools python-wheel

Zypper Package Manager (Python 3.x)

sudo zypper install python3-pip python3-setuptools python3-wheel

This is the one-liner I copy-and-paste:

curl https://bootstrap.pypa.io/get-pip.py | python3

Alternate:

curl -L get-pip.io | python3

From Installing with get-pip.py:

To install pip, securely download get-pip.py by following this link: get-pip.py. Alternatively, use curl:

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

Then run the following command in the folder where you have downloaded get-pip.py:

python get-pip.py

Warning: Be cautious if you are using a Python install that is managed by your operating system or another package manager. get-pip.py does not coordinate with those tools, and may leave your system in an inconsistent state.

If you use several different versions of python try using virtualenv http://www.virtualenv.org/en/latest/virtualenv.html#installation

With the advantage of pip for each local environment.

Then install a local environment in the current directory by:

virtualenv -p /usr/local/bin/python3.3 ENV --verbose

Note that you specify the path to a python binary you have installed on your system.

Then there are now an local pythonenvironment in that folder. ./ENV

Now there should be ./ENV/pip-3.3

use ./ENV/pip-3.3 freeze to list the local installed libraries.

use ./ENV/pip-3.3 install packagename to install at the local environment.

use ./ENV/python3.3 pythonfile.py to run your python script.

pip is installed together when you install Python. You can use sudo pip install (module) or python3 -m pip install (module).

Please follow below steps to install python 3 with pip:

Step 1 : Install Python from download here

Step 2 : you’ll need to download get-pip.py

Step 3 : After download get-pip.py , open your commant prompt and go to directory where your get-pip.py file saved .

Step 4 : Enter command python get-pip.py in cmd.

Step 5 : Pip installed successfully , Verify pip installation by type command in cmd pip --version

And for Windows 8.1/10 OS Users just open cmd (command prompt)

write this : C:\Users\%USERNAME%\AppData\Local\Programs\Python\Python36-32\Scripts

then

just write this : pip3 install {name of package}

Hint: the location of folder Python36-32 may get different for new python 3.x versions

If you used the command "python get-pip.py", you should have the 'pip' function for Python3. However, 'pip' for Python2 might still be present. In my case I uninstalled 'pip', which removed it from Python2.

After that I ran "python get-pip.py" again. (Make sure that 'get-pip.py' is saved in the same folder as Python3.) The final step was to add the directory with 'pip' command to $PATH. That solved it for me.

=>Easy way to install Python any version on Ubuntu 18.04 or Ubuntu 20.04 follow these steps:-

Step 1: Update Local Repositories:-

sudo apt update

Step 2: Install Supporting Software:-

sudo apt install build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev wget

Step3: Create directory on your home directory To download the newest release of Python Source Code, navigate to the /python-source-files directory and use the wget command:-

mkdir python-source-files

Step 4: Download the Latest Version of Python Source Code:-

wget https://www.python.org/ftp/python/3.7.5/Python-3.7.5.tgz

"you can change python version by just modifies this:-"3.7.5" with the version you want example:-"3.5.2"

Step 5: Extract Compressed Files:-

tar –xf Python-3.7.5.tgz or tar xvzf Python-3.7.5.tgz

Step 6: Test System and Optimize Python:-

cd python-3.7.5 or your version of python.

Step 7: Now configure(Using the ––optimization option speeds code execution by 10-20%.):-

./configure ––enable–optimizations

OR you can also do this also if you facing ssl error:-

./configure --with-openssl

Step 8: Install a Second Instance of Python:-

sudo make altinstall

"It is recommended that you use the altinstall method. Your Ubuntu system may have software packages dependent on Python 2.x.

OR

If you want to Overwrite Default Python Installation/version:-

sudo make install"

Step 9:Now check Python Version:-

python3 ––version

Step 10: To install pip for python3 just go with this command:-

sudo apt-get install python3-pip
