Pipenv
Pipenv就是Requests的作者Kenneth Reitz寫出來(lái)的，我們可以把它看做pip和virtualenv的結(jié)合
記錄下Pipenv，方便以后查看
安裝Pipenv
pip install pipenv
創(chuàng)建虛擬環(huán)境

To activate this project's virtualenv, run pipenv shell.
Alternatively, run a command inside the virtualenv with pipenv run.

安裝包
這里安裝兩個(gè)包，依賴會(huì)添加到Pipfile文件中
pipenv install requests django

記錄依賴
用virtualenv記錄依賴，需要?jiǎng)?chuàng)建requirements.txt，每次添加或者刪除新的依賴需要多次執(zhí)行pip freeze > requierements.txt
使用Pipenv會(huì)自動(dòng)幫我們管理依賴，在創(chuàng)建虛擬環(huán)境的時(shí)候會(huì)自動(dòng)創(chuàng)建Pipfile和Pipfile.lock兩個(gè)文件，在使用pipenv install和pipenv uninstall命令安裝和卸載包的時(shí)候自動(dòng)更新
目錄下有Pipfile和Pipfile.lock
- Pipfile用來(lái)記錄項(xiàng)目依賴列表
- Pipfile.lock記錄了固定版本的詳細(xì)依賴包列表
安裝依賴
pipenv install
查看依賴關(guān)系
(env_test-jaLbPeP-) treehl@ssaw:~/env_test$ pipenv graph
Django==1.11.14
- pytz [required: Any, installed: 2018.5]
requests==2.19.1
- certifi [required: >=2017.4.17, installed: 2018.4.16]
- chardet [required: >=3.0.2,<3.1.0, installed: 3.0.4]
- idna [required: >=2.5,<2.8, installed: 2.7]
- urllib3 [required: >=1.21.1,<1.24, installed: 1.23]
檢查安裝的包的安全性
