python - 没有地方部署Python Flask API项目

Question

我认为将 python api 项目部署到某个地方很容易。但我错了，我无法部署到任何平台。

到目前为止我已经尝试过:

1. Azure、Web 应用和函数应用
2. PythonAnywhere
3. 赫罗库

当我尝试为此安装依赖包时，它们都有问题:scikit-fmm

这是错误消息:

Python 版本是3.7.10Linux

pip install scikit-fmm

感谢 JasonPan 的建议，我知道 Azure Web 应用程序上安装了所有依赖项。

我的应用程序部署也成功，但网站无法运行。我检查了日志，发现了很多错误:

搜索了一段时间并尝试了我在网上找到的 fuser 或 kill 命令，但 Web 应用程序无法识别 fuser，并且 kill 命令不适用于此错误消息:

/home# kill `lsof -i :8000`
-bash: lsof: command not found
kill: usage: kill [-s sigspec | -n signum | -sigspec] pid | jobspec ... or kill -l

使用以下命令:

gunicorn --bind=0.0.0.0 --timeout 600 application:app

这是输出

在高级工具下使用Azure应用程序SSH，真是太痛苦了。我的 ssh 控制台经常断开连接，有时它会为我提供正确的文件夹，然后我可以看到我的 python 代码文件。其他时候它会向我显示一个奇怪的文件夹，其中根本没有我的代码......例如

root@ece8fefe856f:/home# ls
37391ef6fffba0c96cda20c7  ASP.NET  LogFiles  site

更新

经过我的测试，由于最新版本的scikit-fmm与azure web app不兼容，所以我使用了scikit-fmm==2021.1.21版本。它对我有用。

感谢Glenn的提醒，您可以在webssh中使用以下cmd。

apt-get update
apt-get install g++
pip install scikit-fmm==2021.1.21

上一个

不知道您需要在requirements.txt中安装哪些软件包。

我个人建议您使用容器(linux)创建azure web app，这样您可以在部署项目后手动执行脚本来安装项目使用的包。

我还没有在Linux下部署flask应用程序。如果你可以使用windows，我推荐使用windows webapp。
