**1、安装**  
pip install pipenv

**2、用pipenv 创建虚拟环境**  
mkdir test \#创建目录test  
cd test \#进入目录  
pipenv --two \#用python2建立环境 （需要系统安装了python2)  
pipenv --three \#用python3建立环境 (需要系统安装了python3)  
pipenv install requests \#安装requests库  
pipenv install flask==1.1.1 \#安装flask框架版本为1.1.1

**3、激活虚拟环境 pipenv shell**

**4、查看目录文件的依赖关系 pipenv graph**

**5、创建一个包含预发行版的锁文件 pipenv lock**

**Usage**  
$ 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.

$ 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.
