Compatible release clause will bypass downgrade_blacklist

[sko00o]

I noticed some custom_nodes using ~= in requirements.txt .

It will make downgrade_blacklist not work.

How to reproduce this

1. set diffusers in downgrade_blacklist

# ComfyUI/custom_nodes/ComfyUI-Manager/config.ini
[default]
# ...
downgrade_blacklist = diffusers

2. install diffusers in venv

$ pip install diffusers==0.27.2
$ pip list | grep diffusers
diffusers                         0.27.2

3. restart ComfyUI

4. Install custom_nodes StableZero123-comfyui

The requirements.txt in this repo has this line diffusers~=0.21.4

5. check diffusers version again

$ pip list | grep diffusers
diffusers                         0.21.4

I cannot reproduce that issue.
Is your ComfyUI up to date?

Is your ComfyUI up to date?

Yes, I'm using the latest ComfyUI. And the issue is not related to ComfyUI.

Sorry for missing one step in bug reproduction. I should install a higher version diffusers in Step 2.
Considering the ComfyUI does not rely on diffusers. I simply use pip install to mock some custom nodes installation behavior.

For demonstration, I built a docker image with latest ComfyUI and ComfyUI-Manager installed. (https://github.com/sko00o/playground/tree/main/comfyui)

Open this repo in Github Codespace, and follow the steps:

# 1. launch comfyui and downgrade_blacklist will be set automatic
sudo bash comfyui/run.sh

# 2. install diffusers
pip install diffusers==0.27.2
pip list | grep diffusers
# diffusers                 0.27.2

# 3. open WebUI to install `StableZero123-comfyui` by ComfyUI-Manager

# 4. check diffusers version again
pip list | grep diffusers
# diffusers                 0.21.4
