1. Is this request related to a challenge you're experiencing? Tell me about your story.

When using Dify offline, I am unable to correctly install plugin dependencies, even though I know they are missing. I have tried many solutions.

# First, I enter the plugin container bash on a computer that can connect to the internet:
pip download -r "plugin dir/requirements.txt"
# Then, on the offline environment, I use /usr/bin/pip to install the dependencies:
pip install -r "plugin dir/requirements.txt" --no-index --find-links=/app/packages

The installation succeeds, but it doesn't work as expected. I think the issue might be that different plugins use a Python environment different from "/usr/bin/pip." So, I used the "PIP_MIRROR_URL" parameter, which requires setting up an additional "pypiserver" in the offline environment. Even though I set it up, the plugin container can "search," but it cannot "pip install":

pip search numpy -i http://10.xxx.xxx.xxx:xx
>> numpy 2.2.3
pip install numpy -i http://10.xxx.xxx.xxx:xx

Maybe there is an issue with how I set up "pypiserver," but setting it up is undoubtedly extra work. Therefore, I hope to replace the "PIP_MIRROR_URL" parameter with a "PIP_COMMAND_EXTEND" option:

PIP_COMMAND_EXTEND='-i https://pypi.org/simple'
# or
PIP_COMMAND_EXTEND="--no-index --find-links=/app/packages"

This would offer more flexibility.

The following is the Chinese translation of the previous text

我在离线使用dify时，无法正确安装插件依赖，尽管我知道他缺少依赖包，我尝试过很多办法。

# 首先我在能联网的电脑进入plugin 容器 bash
pip download  -r "plugin dir/requirements.txt"
# 然后到离线环境
/usr/bin/pip install -r "plugin dir/requirements.txt"  --no-index --find-links=/app/packages

安装成功了，但是这样不管用，我觉得可能是不同的插件使用的python环境与”/usr/bin/pip“的不一样。

好的，我使用“PIP_MIRROR_URL”参数，这需要我在离线环境中额外搭建”pypiserver“。 尽管我搭建了，但是plugin容器虽然可以“search”到，但是无法”pip install“

pip serach numpy -i http://10.xxx.xxx.xxx:xx
>> numpy 2.2.3
pip install numpy -i http://10.xxx.xxx.xxx:xx

也许是我"pypiserver"搭建有问题吧，但是搭建"pypiserver"，无疑是额外的工作。

因此我希望能将"PIP_MIRROR_URL"参数改为"PIP_COMMAND_EXTEND"

PIP_COMMAND_EXTEND='-i https:///pypi.org/simple'
# 或者
PIP_COMMAND_EXTEND="--no-index --find-links=/app/packages"

这样更灵活一些。

Pretty good suggestion.

Hi, the args you want already exists, it names PIP_EXTRA_ARGS

@Yeuoly

What can I fill in this extension parameter? Because initially, I wanted to bypass' - i 'to specify the local path. It seems that dify has already defaulted to assembling the "- i" parameter inside, but if so, the "PIPEXTRA_SRGS" parameter still cannot be bypassed. 这个扩展参数我能够填写什么？因为一开始，我是想绕过"-i"来指定本地路径。好像dify已经默认拼装"-i"参数在里面，如果是这样“PIP_EXTRA_ARGS”参数仍然无法绕过。

Perhaps I set up 'PIP_SIRROR-URL', so I spelled '- i' (because I didn't know there was' PIPEXTRA_SRGS' at the beginning). However, I have already completed the deployment by setting up Pypiserver. 也许是我设置了“PIP_MIRROR_URL”，所以就会拼“-i”(因为我一开始不知道有“PIP_EXTRA_ARGS”)。 不过我已经通过搭建pypiserver完成部署了。

It's because you have already added PIP_MIRROR_URL, it's duplicate

Great, the deployment now looks more elegant. I was really clumsy at manually rubbing the pip source before. 太棒了，这下部署显得更优雅了，之前手搓pip源真是太拙劣了。
