Python 的包管理工具,相似于 NPM 、Yarn 。python
pyenv
可用,自动安装所需的 Pythons
。Pipfile
,以递归方式自动查找项目。Pipfile
,则自动生成。virtualenv
。Pipfile
。.env
文件(若是存在)。主要命令是 install
, uninstall
和 lock
,它们生成 Pipfile.lock
。这些旨在取代 $ pip
安装使用,以及手动 virtualenv
管理(激活 virtualenv
,运行$ pipenv shell
)。shell
virtualenv
不存在时,将自动建立。[packages]
。Python3
虚拟环境,请运行$ pipenv --three
。Python2
虚拟环境,请运行 $ pipenv --two
。virtualenv
为默认值。shell
将激活 virtualenv
生成一个shell
。run
将从 virtualenv
运行一个给定的命令,并转发任何参数(例如 $ pipenv run python
)。PEP 508
要求。graph
将打印全部已安装依赖项的漂亮图表。$ pipenv Usage: pipenv [OPTIONS] COMMAND [ARGS]... Options: --where Output project home information. --venv Output virtualenv information. --py Output Python interpreter information. --envs Output Environment Variable options. --rm Remove the virtualenv. --bare Minimal output. --completion Output completion (to be eval'd). --man Display manpage. --three / --two Use Python 3/2 when creating virtualenv. --python TEXT Specify which version of Python virtualenv should use. --site-packages Enable site-packages for the virtualenv. --version Show the version and exit. -h, --help Show this message and exit. Usage Examples: Create a new project using Python 3.7, specifically: $ pipenv --python 3.7 Remove project virtualenv (inferred from current directory): $ pipenv --rm Install all dependencies for a project (including dev): $ pipenv install --dev Create a lockfile containing pre-releases: $ pipenv lock --pre Show a graph of your installed dependencies: $ pipenv graph Check your installed dependencies for security vulnerabilities: $ pipenv check Install a local setup.py into your virtual environment/Pipfile: $ pipenv install -e . Use a lower-level pip command: $ pipenv run pip freeze Commands: check Checks for security vulnerabilities and against PEP 508 markers provided in Pipfile. clean Uninstalls all packages not specified in Pipfile.lock. graph Displays currently–installed dependency graph information. install Installs provided packages and adds them to Pipfile, or (if no packages are given), installs all packages from Pipfile. lock Generates Pipfile.lock. open View a given module in your editor. run Spawns a command installed into the virtualenv. shell Spawns a shell within the virtualenv. sync Installs all packages specified in Pipfile.lock. uninstall Un-installs a provided package and removes it from Pipfile.
