Python库升级标准流程~

1.检查正在使用的库是否有新的版本:

python 复制代码

pip list -o

输出结果(例):

python 复制代码

Package            Version     Latest    Type
------------------ ----------- --------- -----
astroid            4.0.2       4.1.2     wheel

2.检查该库被谁依赖:

python 复制代码

pip show astroid

输出结果(例):

python 复制代码

Name: astroid
Version: 4.0.2
Summary: An abstract syntax tree for Python with inference support.
Home-page: 
Author: 
Author-email: 
License-Expression: LGPL-2.1-or-later
Location: D:\zhb\Python\thsautobuy\.venv\Lib\site-packages
Requires: 
Required-by: pylint

从结果上看astroid被pylint所调用，需再进一步检查其支持的版本范围:

python 复制代码

pipdeptree --packages pylint

输出结果(例):

python 复制代码

pylint==4.0.5
├── astroid [required: >=4.0.2,<=4.1.dev0, installed: 4.0.4]
├── colorama [required: >=0.4.5, installed: 0.4.6]
├── dill [required: >=0.3.6, installed: 0.4.1]
├── dill [required: >=0.3.7, installed: 0.4.1]
├── isort [required: >=5,<9,!=5.13, installed: 8.0.1]
├── mccabe [required: >=0.6,<0.8, installed: 0.7.0]
├── platformdirs [required: >=2.2, installed: 4.9.6]
└── tomlkit [required: >=0.10.1, installed: 0.15.0]

检查需要更新的库发布了哪些版本:

python 复制代码

pip index versions astroid

输出结果(例):

python 复制代码

  INSTALLED: 4.0.2
  LATEST:    4.1.2

选择正确的升级版本并升级:

astroid库最新版已经发布到4.1.2但是，pylint只支持4.0.2~4.1.dev0之间的版本，所以我们可以将它升级到最高支持的版本4.0.4，方法:

python 复制代码

pip install --upgrade astroid==4.0.4
