Parser for Pipfiles (get a list of all packages used in a Pipfile)

阅读更多关于 Parser for Pipfiles (get a list of all packages used in a Pipfile)

问题 Is there any parser out there for reading in a Pipfile and returning a list of all packages used in the Pipfile? If not, how would one go about this? I was thinking a regular expression could do the job, but I am not sufficiently acquainted with the structure of Pipfiles to confirm that is the case. 回答1: first install pipfile pip install pipfile . then just use the parser it provides from pipfile import Pipfile parsed = Pipfile.load(filename=pipfile_path) 来源： https://stackoverflow.com

So my question is - How to install packages to new env if I already have them in base? --use-locals key or smth else? I found this one

阅读更多关于 Difference between devpi and pypi server

问题 Had a quick question here, am used to devpi and was wondering what is the difference between devpi and pypi server ? Is on better than another? Which of this one scale better? Cheers 回答1: PyPI (Python Package Index)- is the official repository for third-party Python software packages. Every time you use e.g. pip to install a package that is not in the standard it will get downloaded from the PyPI server. All of the packages that are on PyPI are publicly visible. So if you upload your own

问题 I'm developing a Python application and in the process of branching off a release. I've got a PyPI server set up on a company server and I've copied a source distribution of my package onto it. I checked that the package was being hosted on the server and then tried installing it on my local development machine. I ended up with this output: $ pip3 install --trusted-host 172.16.1.92 -i http://172.16.1.92:5001/simple/ <my-package> Collecting <my-package> Downloading http://172.16.1.92:5001
