显示python分布的依赖树
johnnydep的Python项目详细描述
约翰尼德
pretty为python发行版打印依赖树。一个简单的例子：
$ johnnydep requests
name summary
------------------------- ----------------------------------------------------------------------
requests Python HTTP for Humans.
├── certifi>=2017.4.17 Python package for providing Mozilla's CA Bundle.
├── chardet<3.1.0,>=3.0.2 Universal encoding detector for Python 2 and 3
├── idna<2.8,>=2.5 Internationalized Domain Names in Applications (IDNA)
└── urllib3<1.24,>=1.21.1 HTTP library with thread-safe connection pooling, file post, and more.
更复杂的树：
$ johnnydep boto3
name summary
--------------------------------------- -------------------------------------------------
boto3 The AWS SDK for Python

│ └── python-dateutil<3.0.0,>=2.1 Extensions to the standard Python datetime module
│ └── six>=1.5 Python 2 and 3 compatibility utilities
├── jmespath<1.0.0,>=0.7.1 JSON Matching Expressions

johnydep还可以解析依赖树，这是pip经常遇到的问题（^{
