I want to install some specific version of a package (in this case Django) inside the virtual environment. I can't figure it out.
I'm on Windows XP, and I created the virtual environment successfully, and I'm able to run it, but how am I supposed to install the Django version I want into it? I mean, I know to use the newly-created easy_install script, but how do I make it install Django 1.0.7? If I do easy_install django, it will install the latest version. I tried putting the version number 1.0.7 into this command in various ways, but nothing worked.
How do I do this?
There was never a Django 1.0.7. The 1.0 series only went up to 1.0.4. You can see all the releases in the tags section of the Django code repository.
However to answer your question, don't use easy_install, use pip. (If it's not already installed, do easy_install pip, then never touch easy_install again). Now you can do:
pip install Django==1.0.4
+1 on the previous poster's reply: use pip if you can. But, in a pinch, the easiest way is to install an older version would be to download the tarball from the downloads page or, if you have subversion installed, do an svn export of the release you want (they are all tagged here).
Once you have the version of Django you want, just run the following command inside the django directory:
python setup.py install
This will install that version of Django in your virtualenv.
+1 for already mentioned solutions.
I just wanna add another solution.
To install a specific version of Django (say 1.10.x),
Clone the Django repo from Github.
git clone https://github.com/django/django.git
Go into the directory and checkout to the specific branch.
cd django
git checkout origin/stable/1.10.x
Run install command.
python setup.py install
pip install "django>=2.2,<3"
To install djnago 2.2
pip install django==(the desired version ex: 1.8.4)
This will allow you to install the desired version, and I tried on OS:Windows10 and it perfectly worked.

Trying to install coremltools. I installed using pip but that is not the most recent version and I have run into a bug that was solved 4 days so I must build from source. I'm on a Mac virtual desktop(windows user) and I tried cmake, but since there are multiple pythons it keeps trying to install to python 3.7 when I need it to install for python 2.7.10. The github suggest doing this:
cmake . -DPYTHON=$(which python) -DPYTHON_CONFIG=$(which python-config)
.. however as someone who doesn't use cmake for package installs I'm unsure of the correct syntax could someone give me an example statement to go off of, I would really appreciate it. Thanks
You can install it without building it manually:
pip install https://github.com/apple/coremltools/archive/master.zip
You can replace "master" with any branch or tag names.
EDIT: To update an existing install add the -U flag. Or uninstall previous installations.
I am new to Python and there are some things which I am not able to apprehend. Questions may seem like very kiddish, so bear with me.
As you know, Ubuntu comes with an outdated Python version. I wished to use the latest python. But since it is recommended not to override the system's python, I installed virtualenv.
I installed pip first, using sudo apt-get install python-pip.
Then installed virtualenv, using sudo pip install virtualenv, and did all the configurations required to link it to the latest python.
The questions which I want to ask are-
Where does the command pip install <module> store the module in the system? I am asking this question because there is a section in this link, which says "Installation into Python". I was confused by this, thinking whether installing a python module is sensitive to which python version I am using. If it is so, then where does pip install the module if I am using virtualenv and otherwise.
I have manually installed Apache HTTP Server 2.4.23 using this link. While installing mod_wsgi using command sudo pip install mod_wsgi, I am getting this error
RuntimeError: The 'apxs' command appears not to be installed or is not
executable. Please check the list of prerequisites in the
documentation for this package and install any missing Apache httpd
server packages.
I searched for it and the solution is to install developer package of Apache. But the problem is that I am not able to find it anywhere on it's site. I want to install it manually. What to do? Also, If I install it through sudo apt-get install apache2-dev, Will there be any difference ?
Note: As mentioned on this link, I have already set the value of APXS environment variable to the location of apxs script, which is /usr/local/apache/bin/apxs.
Concerning 1., if I have well understood, you would like to have the last 2.7 or 3.5 Python version on your distribution. Actually, you can have multiple python distribution on your distribution. I would suggest you to have a look on conda/anaconda (https://www.continuum.io/downloads) : it is very powerful and i think it would better suit you than virtualenv: virtualenv would enable you to create a separate python environnement, but it would not install a newer version of Python.
Concerning 2, I am not an expert in Apache2, but I would have used apt-get instead of re-compiling apache. While compiling, you may need some dependancies to build the mod_wsgi module. So I think it is way more easy to use the pre-built packages from your ubuntu.
I was having problems with one package not doing what I read in it's documentation, until I noticed that pip installed a outdated version.
On the pip package page it would seem like it was last update 2014, but when I installed, the package files were versioned mid 2013.
How does updating pip packages work and who should be doing it? The project maintainer (on github, or on pip pages?)?
All packages that can be downloaded with PIP are actually hosted on the Python Package Index. The Python organization collaborates with project maintainers to host the projects.
The problem with having outdated packages on pip that do not align with the documentation and current state on github can be really annoying. Despite that you did not ask for a workaround I would like to contribute one in case that other users might land on this page looking for such.
First uninstall the package you installed via pip before:
pip uninstall package
Next install the latest version directly from the github repo:
pip install git+https://github.com/user/package.git
The cool thing about this is that you can still manage your packages with pip but your not limited by what version is available on the Python Package Index.
sorry for asking a probalby stupid question, however, I am completely new to setting up/installing python packages, i.e. I have never done it.
So far I installed anaconda3 and worked with the pre installed packages. Now I need the google api pyhon client.
I do not even know whether pip is installed in the anaconda package but I assume it.
What have I tried so far:
In Windows cmd:
1. pip install --upgrade google-api-python-client
2. pip install -- proxy="XXX.XXX.XX.X:XX" -- upgrade google-api-python-client
3. export https_proxy="...."
pip install --upgrade google-api-python-client
I get the following errors:
cannot fetch index base url https://pypi.python.org/simple
unknown command
unknown command
In addition I tried to download the google_api_python_client and unzipped it.
However, I do not know how to proceed here.
BTW: Here in my company we are still on XP
Any help would be highly appreciated!
THANK YOU
Would like to add to the answer by #alok-nayak that you should use the following:
python setup.py install
Leads to:
Installed ~/anaconda/lib/python2.7/site-packages/google_api_python_client-1.4.2-py2.7.egg
After unzipping google_api_python_client. You should run the setup.py file
python setup.py
Also you can edit ".condarc" file in your home folder, as explained here http://conda.pydata.org/docs/config.html . enter your proxy details there
I'm aware that there are similar questions on SO. This one, for example: What's the proper way to install pip, virtualenv, and distribute for Python?
I'd like to install these modules as per my Learn Python the Hard Way tutorial: http://learnpythonthehardway.org/book/ex46.html
I managed (I think) to install pip by using sudo easy_install pip but when I then ran pydoc modules I could not see it. So I'm not even sure it's installed.
The answer above in question 4324558 is difficult for me to understand: what's a bootstrap, what's curl and why would I set up a virtual environment? Yes, as a learner I should try to pick up as much as I can but I don't want to first create the universe, I just want to get the task at hand done.
How do I install these modules? Is it as complicated as it sounds in the quoted answer? The top voted answer says "Install virtualenv into a bootstrap virtual environment. Use the that virtual environment to create more. Since virtualenv ships with pip and distribute, you get everything from one install."
I really don't get what all that means. Isn't there something about the "Zen" of python and a one true way to get things done? Or am I out of context here? What is "the right way" to install these modules?
I tried:
pip install virtualenv in the terminal and received the following output:
Wheel installs require setuptools >= 0.8 for dist-info support.
pip's wheel support requires setuptools >= 0.8 for dist-info support.
Storing debug log for failure in /Users/myname/.pip/pip.log
I'm using a Mac and python 2.7
To solve your issue,
Just install (or upgrade) the setuptools:
sudo easy_install -U setuptools
Then you can run again: pip install virtualenv
Try adding 'sudo' in your command as-
sudo pip install virtualenv
It worked for me.
Have a look at Python Development Environment on Mac OS X Mavericks 10.9.
I followed these steps as well when trying to get Python 2.7 and Python 3.3 installed on OS X. It doesn't tell you how to install nose and distribute, but you should have a working environment and you can pick up from there.
I did have a problem using virtualenv and pip with Python 3, the question and solutions is available here.
