easyprocess.EasyProcessCheckInstalledError: cmd=['Xvfb', '-help'] OSError=[Errno 2] No such file or directory

I'm trying to setup a display but it's telling me No such file or directory.

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))

Solution

  • You likely need to install either the xvfb package, or possibly the xvfbwrapper:

    First check and see if xvfb is installed:

    Xvfb -help

    If the command is not found then you can usually install the xvfb package with the following command (or whichever package manager you generally use):

    sudo apt-get install xvfb

    xvfbwrapper is Python wrapper for running a display inside X virtual framebuffer (Xvfb).

    You can install it with:

    pip install xvfbwrapper

    The error you are getting seems to be a result of either the command or module not being found.
