问题描述
如何列出我直接用pip安装的软件包，从而省去了由此产生的任何依赖关系?
How do I list packages that I have directly installed with pip, omitting any dependences that have been installed as a result?
我有一个运行过的virtualenv，像这样的命令
I have a virtualenv in which I've run, commands like
$ pip install A B C
$ pip install X Y Z
因此，我不仅安装了A，B，C，X，Y和Z，而且还安装了依赖项p，q，r，s，t，u，v和w.但是查看任何给定的软件包，我都无法回忆起它是否是我直接安装的.我想将直接安装的软件包保留在此venv中，并使用类似的
as a result of which I have installed not only A, B, C, X, Y, and Z, but also dependences p, q, r, s, t, u, v, and w. But looking at any given package, I can't recall whether it was something I installed directly or not. I would like to keep the directly installed packages in this venv uptodate with something like
$ pip install -U --directly-installed
具有以下效果的
that has the effect of
$ pip install -U A B C X Y Z
是否有办法仅使直接安装的软件包保持最新状态(仅按那些软件包的要求更新其依赖性)?
Is there a way to keep only the directly installed packages explicitly up to date (updating their dependences only as required by those packages)?
推荐答案
在工作中，我们手动处理直接安装的软件包的列表.也就是说，如果我们需要一个包，则将其添加到requirements.txt并运行
At the job we handle the lists of directly installed packages manually. That is, if we need a package we add it to requirements.txt and run
pip install -r requirements.txt
之后，我们运行
pip freeze > requirements-freezed.txt
保存软件包和依赖项的完整列表.当我们需要重新创建虚拟环境时，我们运行
to save the entire list of packages and dependencies. When we need to recreate a virtual environment we run
pip install -r requirements-freezed.txt
您的仅升级直接安装的软件包的任务将是
Your task to upgrade only directly installed packages would be
pip install -U -r requirements.txt
pip freeze > requirements-freezed.txt
