pip相关工具使用小结

最近写taffy的时候用到了两个pip相关的小工具。

一个是pip-review批量更新lib库,一个是pipreqs生成基于项目的requirements.txt。

1. pip相关命令

#更新单个lib(不能批量更新)
$ pip install --upgrade xxx #生成全部requirements.txt(不能基于项目生成)
$ pip freeze > requirements.txt

2. pip-review

github地址:https://github.com/jgonggrijp/pip-review

使用pip install直接安装即可:

$ pip install pip-review

基本使用方法:

#查看可更新lib
$ pip-review #自动批量升级lib
$ pip-review --auto #以交互方式运行,对每个包进行升级
$ pip-review --interactive

3. pipreqs

github地址:https://github.com/bndr/pipreqs

同样使用pip install命令安装即可:

$ pip install pipreqs

用法:

Usage:
pipreqs [options] <path> Options:
--use-local Use ONLY local package info instead of querying PyPI
--pypi-server <url> Use custom PyPi server
--proxy <url> Use Proxy, parameter will be passed to requests library. You can also just set the
environments parameter in your terminal:
$ export HTTP_PROXY="http://10.10.1.10:3128"
$ export HTTPS_PROXY="https://10.10.1.10:1080"
--debug Print debug information
--ignore <dirs>... Ignore extra directories
--encoding <charset> Use encoding parameter for file open
--savepath <file> Save the list of requirements in the given file
--print Output the list of requirements in the standard output
--force Overwrite existing requirements.txt
--diff <file> Compare modules in requirements.txt to project imports.
--clean <file> Clean up requirements.txt by removing modules that are not imported in project.

示例:

#生成location项目requirements.txt
$ pipreqs /home/project/location
Successfully saved requirements file in /home/project/location/requirements.txt #覆盖生成requirements.txt
$ pipreqs --force /home/project/location
