Question

我在uwsgi环境下得到一个CalledProcessError，而我可以在django normal runserver-mode中运行它，并且可以直接在命令行中正确运行该命令。这是我的环境：环境：

和我的uwsgi配置：

[uwsgi]
vhost = true
plugin = python36
socket = /tmp/site.sock
master = true
enable-threads = true
processes = 4
virtualenv = /www/env/
home = /www/env
chdir = /www/site/
module = site.wsgi
chomod-socket = 664
uid = www-data
gid = www-data

wkhtmltopdf.sh:
#!/bin/bash
/usr/bin/xvfb-run -a -s "-screen 0 640x480x16" 
/root/wkhtmltox/bin/wkhtmltopdf "$@"

我已经将wkhtmltopdf列为www-data：www-data，这仍然无法正常工作，我不知道它是否与特权有关。而我的wkhtmltopdf版本是wkhtmltopdf 0.12.4（有补丁的qt），我试图从wkhtmltopdf得到stderr输出，但我只能得到stdout

wkhtmltopdf在uwsgi环境下获取CalledProcessError
