I needed a virtual environment with all the global packages included. I created one, and the global Django version is 1.3.1. Now, I need to upgrade the Django version to 1.4 only in my virtual environment. I switched to my environment by activating it, and tried
sudo pip install Django=1.4
It was installed,not in the virtual env but in the global dist-packages.
How to install a package only in the virtual environment?
After you switch to the virtual environment with the activate script. Just use pip install Django==1.4 no sudo needed.
Alternately you can use pip install -E=/path/to/my/virtual/env Django==1.4 in which case you don't need to switch to the virtual environment first.
If you just want to upgrade a package and don't know the version number you want to upgrade to you can use
pip install <package_name> --upgrade
in your virtualenv. So in your case above the following would work as well:
pip install django --upgrade
Instead of --upgrade just -U is also enough.

I am using conda as the Python3 package management tool, sometimes the conda repo did not contains some Python package. So I have to install it using pip, first I found the anaconda environment folder, the next step switch to the anaconda environment folder:
cd /usr/local/anaconda3/envs/pydolphin
then using this command to install package:
./bin/pip install musicbrainzngs
is there any short way to do this? is it possible to install it the PyCharm IDE the simple way? the PyCharm IDE using conda install by default.
First activate your conda environment:
conda activate <env>
This will switch to the version of pip installed in this environment. Then you can install using pip as per normal which will install it into your conda environment:
pip install musicbrainzngs
I am using a conda environment to install a package and this package have dependencies that's not available in conda, so I have to use pip to install some additional packages in the conda environment. After I did all these:
I tested both:
pip list
and
conda list
And found that some dependencies occur in pip list but not in conda list. Is this OK? Do the packages installed by pip in conda enviroment also effect in this envorment?
Yes, I use a combination of pip install and conda install when setting up the environment for a project I'm working on. It works fine.
However, it is documented here that this combination can lead to issues: https://www.anaconda.com/blog/using-pip-in-a-conda-environment
According to that doc, you ought to first use conda to install as many of your packages as possible, then use pip to install the rest afterwards.
Trying to install django with different version that in system, it shows me:
Installing collected packages: Django
Found existing installation: Django 1.7.11
Not uninstalling django at /home/user/lib/python2.7, outside environment /home/user/webapps/v2_dev/venv
Successfully installed Django-1.8.19
But in fact there is old version
tried with different commands:
./venv/bin/pip install Django==1.8.11
pip install Django==1.8.11
UPDATED:
When I install my packages it shows:
The required version of setuptools (>=16.0) is not available,
and can't be installed while this script is running. Please
install a more recent version first, using
'easy_install -U setuptools'.
(Currently using setuptools 3.1 (/home/user/lib/python2.7/setuptools-3.1-py2.7.egg))
When I do the upgrade:
venv/bin/pip install --upgrade setuptools
Requirement already up-to-date: setuptools in ./venv/lib/python2.7/site-packages (40.5.0)
I arrived at this post while looking for how to force install something in a virtualenv despite it being already installed in the global python. This happens when the virtual env was created with --system-site-packages.
In this situation, for certain packages it may be important to have a local version within the virtualenv, even if for many other packages we can share the global versions. This is the case of pytest, for example. However, pip will refuse to install a package in the virtualenv if it can already find the most recent version in the system site.
The solution is to use pip install --ignore-installed mypackage.
Instead of installing setuptools and Django like ./venv/bin/pip install ..., try to activate your virtual environment first and install the stuff you need afterwards.
Activating virtual environment:
Go to the folder where your virtual environment is located (typically the root folder of your project) and type one of the two:
source venv/bin/activate (Unix-based systems)
venv\Scripts\activate (Windows)
This will ensure that you are not mixing packages installed in different environments.
Forcing reinstall of the packages:
Simple upgrade can be done by adding: --upgrade or -U
Forcing reinstall of the packages can be done by adding: --force-reinstall
In your case (once the environment is activated):
python -m pip install -U --force-reinstall setuptools Django
Step by step:
Deactivate and delete the old virtual environment
Create new environment using python -m virtualenv venv (python 2) or python -m venv venv (python 3)
python above is the interpreter which you want to use in your project. That's the only point where you might want to use for example python3 or some absolute path instead. Later use the code as is.
source venv/bin/activate
Activating the virtual environment
python -m pip install -U pip
If you have issue with ImportError: No module named _internal than probably you are using an old version of pip. Issue is described here
python -m pip install -U --force-reinstall -r requirements.txt
-U --force-reinstall is a bit of an overkill in case of fresh environment, but it will do no harm
Go to the place where your manage.py is located and start the server using python manage.py runserver
The problem was in Webfaction VPS
Need an empty file named sitecustomize.py in the /home/username/webapps/appName/env/lib/python2.
That empty file overrides their python customizations, one of which is to include any packages in the ~/lib/python2.7 directory.
You might need to deactivate your virtual env and activate it again for changes to take effect.
workaround but it works!
in your virtualenv directory change the properties of the pyvenv.cfg file
include-system-site-packages = True
this will cause the packages installed on the main to be used
Main OS I am using are Ubuntu and Windows.
I couldn't find the package in conda.I am using python 3.5.
DRF is now on conda-forge. You can install it by using:
conda config --add channels conda-forge
conda install djangorestframework
More information about conda-forge:
https://conda-forge.github.io/
I have installed it on win7 and ubuntu 16.10.
To install this package with conda run:
conda install -c anaconda django=1.10.5
activate myenv # windows cmd
source activate myenv # linux, MacOS
# Anaconda prompt
pip install djangorestframework
pip install markdown # Markdown support for the browsable API.
pip install django-filter # Filtering support
# verify
conda list # Now you should see it on your list
django takes care of much of the hassle of Web development, so you can focus on writing your app without needing to reinvent the wheel. To install this package with conda run https://anaconda.org/anaconda/django :
conda install -c anaconda django
I just installed django 1.11.3 on Python 3.6.2 Anaconda, Windows 10
This answer was posted inside the question:
The easiest is to go in to conda environment and use pip inside to install Django by doing:
> activate $your_conda_env
> pip install djangorestframework
just typing
pip install django
pip install djangoframework
or use a virtual environment to install those packages for that, first you need to install a virtual environment
pip install virtualenv
then create a new directory and make new virtual environment eg:
mkdir django
cd django
virtualenv django_project1
source django_project1/bin/activate
pip install django
pip install djangoframework
this will install django framework inside the virtual environment
will install django framework in your computer. And also update your pip packages using
pip update $PKG_NAME
eg:
pip update python
I have created one virtual-environment. Inside that I have to install few python packages. For that I need pip package inside virtual environment. How can I install pip inside virtual-environment?
According to the pip documentation, you can install pip in a virtual environment by typing the following command when your virtual environment is activated:
python -m ensurepip --upgrade
For your information, ensurepip is an in-built Python module that serves the purpose of installing pip in your Python environment.
you can also try with upgrading pip command even after no pip installed at you specified virtual location
python -m pip install --upgrade pip
This will give you an error as below but also install latest pip version on virtual location
Can't uninstall 'pip'. No files were found to uninstall.
Successfully installed pip-19.2.3
kindly try above option and let me in case any issue.
Usually, you install pip OUTSIDE of your virtual environment.
But after activating the virtualenv you just run "pip install" inside the environment.
Meaning, you install it outside the virtualenv.
You run "pip install" inside the virtualenv.
You can follow this useful guide:
http://docs.python-guide.org/en/latest/dev/virtualenvs/
When you create a virtual environment for a particular python revision installed in your computer, all the libraries currently installed in your python revision would be copied inside the virtual environment.
Pip is usually default available in your python revision directory.
If not, install it first in your original python install directory.
Then copy the pip.exe to the virtual environment's Scripts directory.
After that execute the below command from your terminal (this is for Windows):
\your_venv_directory_path\Scripts\pip.exe install --upgrade pip
Now you can just type
pip install --upgrade pip
and it should recognise the path to the pip.exe file inside your venv
when creating the virtual-environment, be sure to include pip in the command. e.g:
conda create -n my_env pip python=3.6.8
I would suggest deleting the venv and recreating it using the above command
