container_linux.go:349: 启动容器进程导致 exec: flask: 在 $PATH 中找不到可执行文件

Question

我在 docker 中遇到错误：

$ docker-compose -f docker-compose.yml up -d
Removing policyclassification_web_1
Recreating 9c6607f3968d_policyclassification_web_1 ... error

ERROR: for 9c6607f3968d_policyclassification_web_1  Cannot start service web: OCI runtime create failed: container_linux.go:349: starting container process caused "exec: \"flask\": executable file not found in $PATH": unknown

ERROR: for web  Cannot start service web: OCI runtime create failed: container_linux.go:349: starting container process caused "exec: \"flask\": executable file not found in $PATH": unknown
Encountered errors while bringing up the project.

我的 dockerfile：

Docker-compose.yml：

version: '3.6'
services:
  web:
    build: .
    ports:
      - "5122:5122"

需求.txt：

谁能帮我解决这个问题，我在网站上进行了研发，但没有找到确切的解决方案。

您使用了错误的 Flask 版本，它应该是Flask==1.1.1并尝试。
