Installation Error(Opencv-python version doesn't match requirement)

I already installed all the dependencies, but when i run 'pip install manimlib' i get the following error:

ERROR: Could not find a version that satisfies the requirement opencv-python==3.4.2.17
ERROR: No matching distribution found for opencv-python==3.4.2.17 (from manimlib)

I already edited the requirements.txt and removed the version number for opencv and tried to install opencv separetely (I already have the most recent version), it didn't work. Also, i wasn't able to install the required version by running pipinstall with the version 3.4.2.17 as argument.

There are some similar issues here, but none received a answer that worked for me. Someone please help.

查看專案的 requirements.txt 檔案以查看鎖定的 opencv-python 版本。此問題與相依性解析失敗有關。檢查版本 3.4.2.17 是否仍在 PyPI 上可供使用者的 Python 和 OS 使用。修正可能涉及更新 requirements.txt 或 setup.py 中的版本約束。修改後測試安裝以確認它能正常運作。
