pattern安装 note: This error originates from a subprocess, and is likely not a problem with pip. error: subprocess-exited-with-error

这个错误提示出自子进程，很可能与pip无关。这个错误提示表明在安装pattern库时出现了问题。具体的错误信息可能有所不同，但通常与python版本与安装库的版本不一致有关。要解决这个问题，你可以尝试以下方法：

1. 确认你正在使用的Python版本与所需库的兼容性。可以检查库的官方文档或GitHub页面，查看其支持的Python版本范围。

2. 确保你的pip工具是最新版本。可以运行`pip install --upgrade pip`来更新pip工具。

3. 如果你使用的是虚拟环境，请确保你在正确的虚拟环境中安装库。

4. 可以尝试使用`pip install --no-cache-dir pattern`命令来安装pattern库。这将禁用缓存并重新下载库文件，有时可以解决安装问题。

如果以上方法都不能解决问题，建议查看具体的错误输出信息，以便更好地定位问题所在。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
