错误：找不到匹配的发行版和错误：找不到满足要求的版本

Question

我试图在py -m virtualenv objectremoval命令创建的虚拟环境中安装 GitHub 克隆的要求，但我总是遇到“找不到满足要求的版本”错误。 克隆 repo 后，我执行了以下几行；

错误对于 numpy 来说太长了，你可以通过这个超链接找到它： https ://justpaste.it/7vxkv

此外，检查本地包会显示全局环境中所有已安装的包。 我认为这也是一个相关的问题。

(objectremoval) D:\test1\Deep-Object-Removal>pip list --local

如果我在主虚拟环境文件夹中执行它们where python和where pip命令也不会显示虚拟环境路径。

(objectremoval) D:\test1\Deep-Object-Removal>where python
C:\Program Files\Python310\python.exe
C:\Users\user\miniconda3\python.exe
C:\Users\user\AppData\Local\Microsoft\WindowsApps\python.exe

(objectremoval) D:\test1\Deep-Object-Removal>where pip
C:\Program Files\Python310\Scripts\pip.exe
C:\Users\user\AppData\Roaming\Python\Python310\Scripts\pip.exe
C:\Users\user\miniconda3\Scripts\pip.exe

但是，如果我在 Scripts 文件夹中执行where python和where pip命令，它会添加一个额外的路径：

(objectremoval) D:\test1\Deep-Object-Removal\objectremoval\Scripts>where pip
D:\test1\Deep-Object-Removal\objectremoval\Scripts\pip.exe
C:\Program Files\Python310\Scripts\pip.exe
C:\Users\user\AppData\Roaming\Python\Python310\Scripts\pip.exe
C:\Users\user\miniconda3\Scripts\pip.exe

(objectremoval) D:\test1\Deep-Object-Removal\objectremoval\Scripts>where python
D:\test1\Deep-Object-Removal\objectremoval\Scripts\python.exe
C:\Program Files\Python310\python.exe
C:\Users\user\miniconda3\python.exe
C:\Users\user\AppData\Local\Microsoft\WindowsApps\python.exe

尝试将软件包安装在主文件夹和 Scripts 文件夹中都没有给我想要的结果。

我的 requirements.txt 文件仅包含以下包：

opencv_python==3.3.0.10
tensorflow==1.10.1
numpy==1.13.3

另外，我尝试升级 pip、setuptools 和 wheel 版本。 我还尝试通过conda create -n <venvname>命令使用 conda 创建虚拟环境，并尝试了几个不同的 python 版本，但这些也没有帮助。 你能帮我解决这个问题吗？ 感谢您的宝贵时间。

Python: 3.10.2
OS: Windows10 x64 Pro

亲切的问候，

选择的名为Deep-Object-Removal的包似乎非常过时（上次提交 4 年前）并且不再维护，我建议搜索任何当前支持的替代方案。

如果您尝试在干净的 python venv （使用python3.10 ）中安装此版本的opencv_python ，则会收到错误消息：

pip install opencv_python==3.3.0.10
ERROR: Could not find a version that satisfies the requirement opencv_python==3.3.0.10 (from versions: 3.4.0.14, 3.4.10.37, 3.4.11.39, 3.4.11.41, 3.4.11.43, 3.4.11.45, 3.4.13.47, 3.4.15.55, 3.4.16.57, 3.4.16.59, 3.4.17.61, 3.4.17.63, 3.4.18.65, 4.3.0.38, 4.4.0.40, 4.4.0.42, 4.4.0.44, 4.4.0.46, 4.5.1.48, 4.5.3.56, 4.5.4.58, 4.5.4.60, 4.5.5.62, 4.5.5.64, 4.6.0.66)
ERROR: No matching distribution found for opencv_python==3.3.0.10

如果您查看pypi 中此版本opencv_python的文件，您会注意到此版本的 pkg. 被猛拉。
另外没有pkg。 对于python3.10 ，最后一个支持 whl 文件似乎是python3.6 。
您可以尝试使用较新的opencv_python调整requirements.txt或安装python3.6并手动下载特定版本并安装whl文件，（但这可能会导致新的错误）。 但我再次建议使用另一个当前支持的包而不是 Deep-Object-Removal。
