easyprocess.EasyProcessCheckInstalledError：cmd = ['Xvfb'，'-help'] OSError = [Errno 2]没有这样的文件或目录

问题描述

我正在尝试设置显示器，但告诉我没有这样的文件或目录。

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))
  File "/usr/lib/python2.6/site-packages/pyvirtualdisplay/display.py", line 33, in __init__
    self._obj = self.display_class(
  File "/usr/lib/python2.6/site-packages/pyvirtualdisplay/display.py", line 51, in display_class
    cls.check_installed()
  File "/usr/lib/python2.6/site-packages/pyvirtualdisplay/xvfb.py", line 38, in check_installed
    ubuntu_package=PACKAGE).check_installed()
  File "/usr/lib/python2.6/site-packages/easyprocess/__init__.py", line 209, in check_installed
    raise EasyProcessCheckInstalledError(self)
easyprocess.EasyProcessCheckInstalledError: cmd=['Xvfb', '-help']
OSError=[Errno 2] No such file or directory
Program install error!

推荐答案

您可能需要安装 xvfb 包，或者 xvfbwrapper ：

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

首先检查是否已安装：

Xvfb -help

如果未找到命令 ，那么通常可以使用以下命令（或通常使用的任一软件包管理器）安装 xvfb 软件包：

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

是用于在X虚拟帧缓冲区（Xvfb）内运行显示的Python包装器。

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

您可以使用以下命令安装它：

You can install it with:

pip install xvfbwrapper

您收到的错误似乎是由于找不到命令或模块导致的。

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