这个问题可能是因为你的 pip 版本太旧而导致的。建议你升级 pip,可以使用以下命令:
```
sudo python -m pip install --upgrade pip
```
然后再尝试安装 PyQt5:
```
sudo python -m pip install PyQt5
```
如果还有其他问题,请让我知道。

这个问题可能是因为你的 Python 版本太旧而导致的。PyQt5 已经不再支持 Python 2.7,建议你升级到 Python 3.x 版本,并使用类似以下的命令安装 PyQt5:
```
sudo apt-get install python3-pyqt5
```
或者使用以下命令安装 PyQt5:
```
sudo python3 -m pip install PyQt5
```

您正在尝试使用`pip`安装Python 3.9.7,但是它并不是一个有效的软件包名称,因此无法找到匹配的发行版。
要安装特定版本的Python,请使用以下命令:
```
sudo apt-get install python3.9
```
这将安装Python 3.9版本。请注意,具体的安装命令可能因您使用的操作系统和包管理器而有所不同。上述命令适用于基于Debian的系统,如Ubuntu。
请确保您的操作系统和包管理器支持所需的Python版本,并使用适当的命令进行安装。
