requirements.txt

So I was googling an event where pip required sudo privileges,and I came across the following two threads What are the risks of running 'sudo pip'? and Is it acceptable & safe to run pip install under sudo? The first thread talks about the security risk of running an unknown .py file with pip (makes sense), but from the second one I almost got the impression that there exists a global and local python installation that you should not mix up. I guess it makes it sense that you can have a global installation for all users and then maybe an appended path to local packages for each user, but is

I have a Virtual env for my django project, but when I hit pip freeze , I get what must be a global site package list, includes too many packages, like ubuntu packages and so much irrelevant stuff. This happens whether virtualenv is active or not. My site packages list looks a bit slim too, so I wonder whether venv has been working at all. (env)~/code/django/ssc/dev/env/lib/python2.7/site-packages> ls django Django-1.4-py2.7.egg-info easy-install.pth pip-1.0.2-py2.7.egg setuptools-0.6c11-py2.7.egg setuptools.pth What's my problem? If your virtual environment has access to the system's site

With pip you are able to create a requirements file to specify which libraries to install. Is there an equivalent for perl modules using CPAN? I came across ExtUtils::MakeMaker, but this seems like the make file is for each module specifically. I guess to try and give a better idea of what I am asking is if there is a way to do something like cpan install -r requirements.txt and then specify which modules to install in that requirements file. Thanks in advance! I think Carton is what you're looking for. To start using Carton, install it. Then create a cpanfile with your dependencies: require

I want to be able to add some extra requirements to an own create docker image. My strategy is build the image from a dockerfile with a CMD command that will execute a "pip install -r" command using a mounted volume in runtime. This is my dockerfile: FROM ubuntu:14.04 RUN apt-get update RUN apt-get install -y python-pip python-dev build-essential RUN pip install --upgrade pip WORKDIR /root CMD ["pip install -r /root/sourceCode/requirements.txt"] Having that dockerfile I build the image: sudo docker build -t test . And finally I try to attach my new requirements using this command: sudo docker

I have a project with multiple package dependencies, the main requirements being listed in requirements.txt . When I call pip freeze it prints the currently installed packages as plain list. I would prefer to also get their dependency relationships, something like this: Flask==0.9 Jinja2==2.7 Werkzeug==0.8.3 Jinja2==2.7 Werkzeug==0.8.3 Flask-Admin==1.0.6 Flask==0.9 Jinja2==2.7 Werkzeug==0.8.3 The goal is to detect the dependencies of each specific package: Werkzeug==0.8.3 Flask==0.9 Flask-Admin==1.0.6 And insert these into my current requirements.txt . For example, for this input: Flask==0.9

How do I upgrade all my python packages from requirements.txt file using pip command? tried with below command $ pip install --upgrade -r requirements.txt Since, the python packages are suffixed with the version number ( Django==1.5.1 ) they don't seem to upgrade. Is there any better approach than manually editing requirements.txt file? EDIT As Andy mentioned in his answer packages are pinned to a specific version, hence it is not possible to upgrade packages through pip command. But, we can achieve this with pip-tools using the following command. $ pip-review --auto this will automatically
