Steps to reproduce

I am using version 1.1.1, dify-plugin-daemon version: 0.0.6-local,
[ERROR]init environment failed: failed to install dependencies: exit status 2, output: error: Failed to fetch: https://pypi.tuna.tsinghua.edu.cn/simple/openai/Caused by: Could not connect, are you offline?

After entering the container, I manually downloaded the corresponding dify_plugin dependencies, but it still reported an error.

`
root@2149fb69af59:/app# pip list |grep dify
dify_plugin 0.0.1b65

@dosubot[bot] commented on GitHub (Mar 23, 2025):

I found a similar open issue that might help you resolve the DNS resolution failure and connection errors when trying to install dependencies for the dify-plugin in a self-hosted Docker environment using the Tsinghua University PyPI mirror. The recommended approach is to set the PIP_MIRROR_URL environment variable specifically within the plugin_daemon's container. This is because the dify_plugin packages are not available on the Tsinghua mirror, and setting the mirror URL globally may not work. Ensure that the PIP_MIRROR_URL is correctly configured in the docker-compose.yaml file to 'https://pypi.tuna.tsinghua.edu.cn/simple' for other packages, but handle the dify_plugin packages separately within the container [1][2][3].

You should check your proxy settings.

I found the source code of dify_plugin_daemon and discovered that the proxy configuration items http_proxy and https_proxy need to be in uppercase to take effect. Thank you. The issue has been resolved.
like this：
HTTP_PROXY: 127.0.0.1:7890 HTTPS_PROXY: 127.0.0.1:7890

我找到了 dify_plugin_daemon 的源码，发现代理配置项 http_proxy 和 https_proxy 需要大写才能生效。谢谢。此问题已解决。 喜欢这个： HTTP_PROXY: 127.0.0.1:7890 HTTPS_PROXY: 127.0.0.1:7890

请问是在哪个文件改呢

我发现了一个类似的公开问题，它可能有助于您解决在自托管 Docker 环境中尝试安装 dify-plugin 时出现的 DNS 解析失败和连接错误的问题。推荐的方法是在 plugin_daemon 容器内设置 PIP_MIRROR_URL 环境变量。因为 dify_plugin 包在 Tsinghua 镜像中不可用，设置镜像 URL 可能不会生效。确保在 docker-compose.yaml 文件中正确配置 PIP_MIRROR_URL 为 'https://pypi.tuna.tsinghua.edu.cn/simple' 以便其他包可以使用，但在容器内单独处理 dify_plugin 包 [1][2][3]。
