Easyprocess.EasyProcessCheckInstalledError: cmd = ['Xvfb', '-help'] OSError = [Errno 2] There is no such file or directory

Question

I am trying to customize the display, but it tells 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))

    raise EasyProcessCheckInstalledError(self)

Program install error!

Answer 1

You probably need to install either the package xvfb, or perhaps xvfbwrapper:

First check and see if xvfb is installed :

Xvfb -help

If the command is not found, you can usually install the package xvfbusing the following command (or any other package manager that you usually use):

sudo apt-get install xvfb

xvfbwrapper - Python X (Xvfb).

:

pip install xvfbwrapper
