What does the “-U” option stand for in pip install -U

由 断了今生、忘了曾经 提交于 2020-07-31 06:19:47
问题 Despite a ton of Googling, I can't find any docs for pip's command line options/arguments. What does pip install -U mean? Does anyone have a link to a list of pip's options and arguments? 回答1: Type pip install -h to list help: -U, --upgrade Upgrade all packages to the newest available version So, if you already have a package installed, it will upgrade the package for you. Without the -U switch it'll tell you the package is already installed and exit. Each pip subcommand has its own help

How does PIP determine the version of a dependency of multiple dependents

问题 Let's assume we have the following dependency tree in Python using PIP as package installer: A==1.2.1: | - B==1.5.4 | - C==?.?.? D==1.3.0: | - C==?.?.? Let's also assume that the existing versions of package C are the followings: - 0.0.8 - 1.0.2 As we know, PIP will not install different versions of the same package into an environment. Which means it has to pick one suitable version for all dependents. What I simply cannot understand how PIP determines the suitable version. If package A

问题 I'm setting up virtual env. I was getting warnings about an outdated pip (19.2) so I updated pip on my (macos) system globally, sudo -H python3 -m pip install --upgrade pip . It seems to have worked, but when I make a new venv, I'm still getting the old pip version. % pip --version pip 20.1 from /Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/pip (python 3.8) % python3 -m pip --version pip 20.1 from /Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8

前言 大家都知道Python有自带的单元测试框架unittest，那为什么还要学习Pytest呢？先了解下Pytest优点 pytest: pytest是一个非常成熟的全功能的Python测试框架，是unittest框架的扩展，主要特点有以下几点： 1、简单灵活，非常方便的组织自动化测试用例； 2、支持参数化，可以细粒度地控制要测试的测试用例； 3、能够支持简单的单元测试和复杂的功能测试，比如web端selenium/移动端appnium等自动化测试、request接口自动化测试 4、pytest具有很多第三方插件，并且可以自定义扩展，比如测试报告生成，失败重运行机制 5、测试用例的skip和fail处理； 6、结合业界最美的测试报告allure+Jenkins，持续集成 selenium ： 基于 JavaScript 代码库的自动化测试框架，通过脚本语言，模拟用户行为操作，最接近用户真实场景，实现对 web 自动测试。 Selenium ，是目前的最火爆企业最主流的 webUI 自动化框架 环境搭建 pip install -U pytest pytest-xdist # 多线程 pip install -U pytest-rerunfailures # 重试运行 cases pip install pytest-html # 生成测试报告 pytest --version #
