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

到目前为止，我已经尝试：

  1. Azure、Webapp和功能应用程序
  2. Python之家
  3. 赫罗库

当我尝试为这一个安装依赖项包时，它们都有问题： scikit-fmm

以下是错误消息：

Python版本是 3.7.10 Linux

pip install scikit-fmm

感谢JasonPan的建议，我知道Azure web app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，发现了许多错误：

搜索了一会儿并尝试了我在网上找到的fuser或kill命令，但fuser在Web app上无法识别，并且kill命令无法处理此错误消息：

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

更新2

使用以下命令：

gunicorn--bind=0.0.0.0--timeout 600应用程序：应用程序

这是输出

在高级工具下使用Azure app SSH，真是太痛苦了。 我的ssh控制台经常断开连接，有时它会为我找到正确的文件夹，然后我可以看到我的python代码文件。有时它会显示一个奇怪的文件夹，里面根本没有我的代码。。。。 e、 g

您可以选择通过Heroku Docker注册表在本地构建映像并（测试后）将其推送到Heroku进行部署。优点是您可以控制构建（而不是Heroku）

定义Python应用程序的Dockerfile（下面的示例）

FROM python:3.9-slim

COPY app/ /app

EXPOSE 5000

WORKDIR /app
RUN pip install -r requirements.txt

ENTRYPOINT ["python"]
CMD ["app.py"]

本地构建映像（使用Heroky要求的命名约定，即appname）

# build image
docker build -t registry.heroku.com/appname/web .

图像应包含您的应用程序以及您需要的所有依赖项/模型。您可以使用docker run在本地测试这一点

按下并释放图像：

# login into Docker Registry (only once)
heroku container:login
# push
docker push registry.heroku.com/appname/web
# release
heroku container:release web -a appname

g++命令的127状态代码表明g++未安装在您尝试安装的平台上。在所有平台上都会出现相同的错误吗

更新

测试之后，由于scikit-fmm的最新版本与azure web app不兼容，我使用了scikit-fmm==2021.1.21版本。它对我有用

enter image description here

感谢Glenn的提醒，您可以在WebSh中使用下面的cmd

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

以前的

不知道需要在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，以便您可以在部署项目后手动执行脚本以安装项目使用的软件包

我没有在Linux下部署flask应用程序。如果您可以使用windows，我建议您使用windows webapp

你可以在下面的帖子中参考我的答案。
