python – easyprocess.EasyProcessCheckInstalledError:cmd = [‘Xvfb’,’ – help’] OSError = [Errno 2]没

我正在尝试设置显示器,但它告诉我没有这样的文件或目录.
Traceback (most recent call last):
File "/var/www/envs/venv/proj/scripts/my_file.py", line 44, in click
display = Display(visible=0, size=(800,600))

ubuntu_package=PACKAGE).check_installed()

raise EasyProcessCheckInstalledError(self)
easyprocess.EasyProcessCheckInstalledError: cmd=['Xvfb', '-help']
OSError=[Errno 2] No such file or directory
Program install error!
解决方法:
您可能需要安装xvfb软件包,或者可能需要安装xvfbwrapper:
首先检查并查看是否安装了xvfb:
Xvfb -help
如果找不到该命令,那么通常可以使用以下命令(或通常使用的软件包管理器)安装xvfb软件包:
sudo apt-get install xvfb
xvfbwrapper是用于在X虚拟帧缓冲区(Xvfb)内运行显示的Python包装器.
你可以安装它:
pip install xvfbwrapper
您获得的错误似乎是由于找不到命令或模块.
