一、说明
使用 pipreqs 可以自动检索到当前项目下的所有组件及其版本,并生成 requirements.txt 文件,极大方便了项目迁移和部署的包管理。相比直接用 requirements.txt 命令,能直接隔离其它项目的包生成。
二、安装
pip install pipreqs
三、官方例子
- 帮助文档
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.
--no-pin Omit version of output packages.
执行 pipreqs 命令
# Successfully saved requirements file in /home/project/location/requirements.txt
$ pipreqs /home/project/location
四、项目执行
- 当前项目根目录下,执行 pipreqs 命令,不加 –encoding=utf8 会出现编码问题
> pipreqs ./ --encoding=utf-8
> pipreqs . --encoding=utf-8
- 强制执行命令 –force ,覆盖原有的 requirements.txt 文件
> pipreqs ./ --encoding=utf-8 --force
