On Ubuntu 10.04 by default Python 2.6 is installed, then I have installed Python 2.7. How can I use pip install to install packages for Python 2.7.
For example:
pip install beautifulsoup4
by default installs BeautifulSoup for Python 2.6
When I do:
import bs4
in Python 2.6 it works, but in Python 2.7 it says:
No module named bs4
Alternatively, since pip itself is written in python, you can just call it with the python version you want to install the package for:
python2.7 -m pip install foo
Use a version of pip installed against the Python instance you want to install new packages to.
In many distributions, there may be separate python2.6-pip and python2.7-pip packages, invoked with binary names such as pip-2.6 and pip-2.7. If pip is not packaged in your distribution for the desired target, you might look for a setuptools or easyinstall package, or use virtualenv (which will always include pip in a generated environment).
pip's website includes installation instructions, if you can't find anything within your distribution.
You can execute pip module for a specific python version using the corresponding python:
Python 2.6:
python2.6 -m pip install beautifulsoup4
Python 2.7
python2.7 -m pip install beautifulsoup4
In Windows, you can execute the pip module by mentioning the python version ( You need to ensure that the launcher is on your path )
py -2 -m pip install pyfora
You can use this syntax
python_version -m pip install your_package
For example. If you're running python3.5, you named it as "python3", and want to install numpy package
python3 -m pip install numpy
Have tried this on a Windows machine and it works
If you wanna install opencv for python version 3.7, heres how you do it!
py -3.7 -m pip install opencv-python
Alternatively, if you want to install specific version of the package with the specific version of python, this is the way
sudo python2.7 -m pip install pyudev=0.16
if the "=" doesnt work, use ==
x#ubuntuserv:~$ sudo python2.7 -m pip install pyudev=0.16
Invalid requirement: 'pyudev=0.16'
= is not a valid operator. Did you mean == ?
x#ubuntuserv:~$ sudo python2.7 -m pip install pyudev==0.16
works fine
If you have both 2.7 and 3.x versions of python installed, then just rename the python exe file of python 3.x version to something like - "python.exe" to "python3.exe". Now you can use pip for both versions individually. If you normally type "pip install " it will consider the 2.7 version by default. If you want to install it on the 3.x version you need to call the command as "python3 -m pip install ".
Python 2
sudo pip2 install johnbonjovi
Python 3
sudo pip3 install johnbonjovi
For Python 3
sudo apt-get install python3-pip
sudo pip3 install beautifulsoup4
For Python 2
sudo apt-get install python2-pip
sudo pip2 install beautifulsoup4
On Debian/Ubuntu, pip is the command to use when installing packages
for Python 2, while pip3 is the command to use when installing
packages for Python 3.
for python2 use:
py -2 -m pip install beautifulsoup4
I faced a similar problem with another package called Twisted. I wanted to install it for Python 2.7, but it only got installed for Python 2.6 (system's default version).
Making a simple change worked for me.
When adding Python 2.7's path to your $PATH variable, append it to the front like this: PATH=/usr/local/bin:$PATH, so that the system uses that version.
If you face more problems, you can follow this blog post which helped me - https://github.com/h2oai/h2o-2/wiki/installing-python-2.7-on-centos-6.3.-follow-this-sequence-exactly-for-centos-machine-only
As with any other python script, you may specify the python installation you'd like to run it with. You may put this in your shell profile to save the alias. The $1 refers to the first argument you pass to the script.
# PYTHON3 PIP INSTALL V2
alias pip_install3="python3 -m $(which pip) install $1"
I'm using Ubuntu 22.04, which comes with python 3.10.4.
Some packages do not have recent pip packages, so I needed install from an older pip. This sequence worked for me.
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt-get update
sudo apt-get install python3.9
sudo apt install python3.9-distutils
python3.9 -m pip install onnxruntime-gpu
Folder location: /usr/local/lib/python3.8
Package: python3.8 -m pip install <package_name>
I had Python 2.7 installed via chocolatey on Windows and found pip2.7.exe in C:\tools\python2\Scripts.
Using this executable instead of the pip command installed the correct module for me (requests for Python 2.7).
I think the best practice here is not to use the system python or install any system python package (no apt install). That is just the way to trouble.
Instead, build the required Python version from source, get it installed in /usr/local/... . Then use pip to install packages for that. It is really not that hard to build Python from source on Ubuntu.
sudo apt install build-essential
download the source from https://www.python.org/downloads/source/
unpack the file downloaded: tar xf <filename>
cd <directory> - change into the directory created.
./configure
make
sudo make install
Then check /usr/local/bin for a pip script tied to that version. Use that to pip install whatever you need. Also find the particular executable for the python version in that directory. You might have to shuffle things a bit if you get lots of versions.
Again, do not mess with system python.
I installed python3 from the official website and then installed jupyter notebook. While trying to run jupyter notebook, I was getting a "command not found" error.
I found this github issue and followed the instructions to delete python3 and reinstall using Homebrew instead (I've used Homebrew before).
When trying python3 -m pip install --upgrade pip i get a "No module named pip" error. My /usr/local/bin/ file shows pip, pip2, pip2.7, pip3, pip3.6.
I have a feeling my pip is not associated with the python3 that I installed using Homebrew. How can I fix this?
This way is a pretty fool-proof way to install pip for a specific python interpreter, when you have a big mess of them on the machine:
$ curl https://bootstrap.pypa.io/get-pip.py > /tmp/get_pip.py
$ my_python_interpreter /tmp/get_pip.py
Then:
$ my_python_interpreter -m pip install some_dist
I've been using Ubuntu 17.04 but my pip install is not working. Pip3 works fine and I've been getting by using python3 but I want to use volatility plugins with vol.py and I need python2 for that.
pip install just runs normally and installs everything fine but when I import it it says it's not installed. And yes I've tried using pip2, python -m pip, etc-- python -m pip just gives some error about no zlib when I've already installed it (zlib package thing). Help?
You can specify which version of python you want to use
Try this
python3.6 -m pip install <package>
or
python3 -m pip install <package>
So we currently use python 2.6 for production, and I just installed pip but couldn't get any output from cmd on windows 10. Then I tried with python -m pip ... then I got d:\Python26\python.exe: pip is a package and cannot be directly executed, it's quite annoying so how do I fix this problem?
pip is a standalone executable, not package. After using get-pip.py for installing pip, you should have pip executable in d:\Python26\. Go to that folder to check if pip is there:
cd d:\Python26\
pip freeze
Then you need to add pip to your PATH: https://superuser.com/a/949573
I'm trying to install lxml for Centos6.3, due to this issue. It looks like I've got a conflicting version of pip. The standing solution seems to re-install pip for the correct version of python.
My main issue is that all the methods I've found for installing pip require an internet connection. Is it possible to download pip install files, and then run pip install -U pip and point it at the right files?
The PyPI page for pip only has pip6.11 as a .whl. I've tried running pip install -U pip-6.1.1-py2.py3-none-any.whl and it's not worked.
I'm stumped. How do I install it?
You could try to download pip and setuptools manually from: https://pypi.org/project/pip/#files and https://pypi.org/project/setuptools/#files
get the python pip script from: https://bootstrap.pypa.io/get-pip.py
after that unzip/untar packages and run:
python get-pip.py --no-index --find-links=/path/to/pip-and-setuptools
or alternatively trying:
python setup.py install when running in unpacked folders
