Docker运行找不到可执行文件“uwsgi”

我正在尝试使用 Docker 部署 falcon 应用程序。这是我的 Dockerfile：

FROM python:2-onbuild

# Set the working directory to /app
WORKDIR /app

# Copy the current directory contents into the container at /app
ADD . /app

RUN pip install -r ./requirements.txt
RUN pip install uwsgi

EXPOSE 8000

CMD ["uwsgi", "--http”, " :8000" , "—wsgi-file”, "falconapp.wsgi"]

但是我不断收到错误消息：

/bin/sh: 1: [uwsgi,: not found

我尝试在本地目录中运行 uwsgi ，它与以下命令配合得很好：

uwsgi --http :8000 --wsgi-file falconapp.wsgi

为什么 Docker 在这种情况下不起作用？？？

这是日志，我很确定 uwsgi 已安装：

很多时候你必须为可执行文件编写完整的补丁。如果您转到容器并运行此命令whereis uwsgi它会告诉你现在是/usr/local/bin/uwsgi所以你的 CMD 应该采用相同的形式：

CMD ["/usr/local/bin/uwsgi", "--http", " :8000" , "--wsgi-file", "falconapp.wsgi"]
