python - Docker - Ubuntu 中的主管抛出 ENOEXEC 错误

Question

我有一个正在运行的 Ubuntu Docker 容器，其中安装了 python3.7、mongodb 和 supervisor。当我尝试通过主管服务运行我的 python 脚本时，它会抛出以下错误:

supervisor: couldn't exec /data/code/venvs/cleverInvest/bin/python: ENOEXEC
supervisor: child process was not spawned

supervisor.conf

[supervisord]
;logfile=/var/app/logs/ ; (main log file;default $CWD/supervisord.log)
logfile_maxbytes=50MB        ; (max main logfile bytes b4 rotation;default 50MB)
logfile_backups=5           ; (num of main logfile rotation backups;default 10)
loglevel=debug                ; (log level;default info; others: debug,warn,trace)
pidfile=/tmp/supervisord.pid ; (supervisord pidfile;default supervisord.pid)
nodaemon=true                ; (start in foreground if true;default false)
minfds=1024                  ; (min. avail startup file descriptors;default 1024)
minprocs=200                 ; (min. avail process descriptors;default 200)

我已经尝试将 !#/bin/sh 添加到 python 文件，或者给他们一个 777 规则。似乎没有任何帮助。

这是我的 Dockerfile

所以我自己弄明白了，我想写下我的解决方案，以防其他人遇到同样的问题。

我只是通过使用全局安装的 python 版本而不是通过 th virtualenv 更改了我启动 python 脚本的方法。 所以我的 supervisor.conf 文件现在看起来像这样:

[supervisord]
;logfile=/var/app/logs/ ; (main log file;default $CWD/supervisord.log)
logfile_maxbytes=50MB        ; (max main logfile bytes b4 rotation;default 50MB)
logfile_backups=5           ; (num of main logfile rotation backups;default 10)
loglevel=debug                ; (log level;default info; others: debug,warn,trace)
pidfile=/tmp/supervisord.pid ; (supervisord pidfile;default supervisord.pid)
nodaemon=true                ; (start in foreground if true;default false)
minfds=1024                  ; (min. avail startup file descriptors;default 1024)
minprocs=200                 ; (min. avail process descriptors;default 200)

[program:mongod]
;command=/usr/bin/mongod --config /etc/mongod.conf
command=/usr/bin/mongod
stdout_logfile=/var/log/supervisor/%(program_name)s.log
stderr_logfile=/var/log/supervisor/%(program_name)s.log
autorestart=true
user=mongodb
priority=100

[program:server]
priority=10
directory=/data/code/
command=python3 server.py
;command=/data/code/venvs/cleverInvest/bin/python /data/code/server.py
user=root
autostart=true
autorestart=true

[program:cleverinvest]
priority=10
directory=/data/code/
command=python3 main.py
;command=/data/code/venvs/cleverInvest/bin/python /data/code/main.py
user=root
autostart=true
autorestart=true

我的脚本文件中也有语法错误。纠正它们后，它起作用了。
