错误说我没有 C 编译器但是安装了 gcc。

答案1

uwsgi已在存储库中。它可能不是 1.9.20 版本，但仍应能满足您的需求（并且uwsgi与 PyPI 基本相同，只是预编译和可安装）。

要安装它及其 Python 3 插件，只需运行：

sudo apt install uwsgi uwsgi-plugin-python3

这将安装uwsgiPython 3 插件。然后您可以uwsgi --plugin=python3 ...照常执行以直接运行它。

话虽如此，如果您不想自己手动运行（尽管在某些情况下您可能需要这样做），您也可以设置uwsgi配置文件/etc/uwsgi/*.ini，然后启动这些服务，sudo systemctl stop uwsgi && sudo systemctl start uwsgi它将自动以守护进程的方式运行。但是，有关此内容的文档位于 uwsgi 的文档中，并且太复杂和深入，我无法在此处复制。我使用它在我的雇主的基于 UWSGI 的基础设施上运行三个 API，并从授权访问 API 点的 Web 端点将数据传递给它们，它工作得非常有效。
