Python 的包管理工具,相似於 NPM 、Yarn 。python
pyenv
可用,自動安裝所需的 Pythons
。Pipfile
,以遞歸方式自動查找項目。Pipfile
,則自動生成。virtualenv
。Pipfile
。.env
文件(若是存在)。主要命令是 install
, uninstall
和 lock
,它們生成 Pipfile.lock
。這些旨在取代 $ pip
安裝使用,以及手動 virtualenv
管理(激活 virtualenv
,運行$ pipenv shell
)。shell
virtualenv
不存在時,將自動建立。[packages]
。Python3
虛擬環境,請運行$ pipenv --three
。Python2
虛擬環境,請運行 $ pipenv --two
。virtualenv
爲默認值。shell
將激活 virtualenv
生成一個shell
。run
將從 virtualenv
運行一個給定的命令,並轉發任何參數(例如 $ pipenv run python
)。PEP 508
要求。graph
將打印全部已安裝依賴項的漂亮圖表。$ 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.
