python - How to update requirements?

Question

I would like to know how to update outdated requirements with the multi requirements files setup that cookie cutter uses (base, local, etc...) ?

If i launch a "pip freeze" it will write the requirements in a single file. It will not dispatch them in correct files

Do I miss something ?

您可以使用以下命令更新所有过时的 python 模块：

Linux：

pip list --outdated --format=freeze | grep -v '^\-e' | cut -d = -f 1 | xargs -n1 pip install -U 

视窗（Powershell）：

pip freeze | %{$_.split('==')[0]} | %{pip install --upgrade $_}

在此之后，您必须更新您requirements.txt的：

pip freeze > requirements.txt

如果您使用Pipenv：

pipenv shell
pipenv update
