问题描述
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.
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,或者可能需要安装 xvfbwrapper:
You likely need to install either the xvfb package, or possibly the xvfbwrapper:
首先查看是否安装了xvfb:
Xvfb -help
如果命令找不到,那么您通常可以使用以下命令(或您通常使用的任何包管理器)安装 xvfb 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
xvfbwrapper 是用于在 X 虚拟帧缓冲区 (Xvfb) 中运行显示的 Python 包装器.
xvfbwrapper is Python wrapper for running a display inside X virtual framebuffer (Xvfb).
你可以安装它:
pip install xvfbwrapper
您遇到的错误似乎是由于找不到命令或模块造成的.
The error you are getting seems to be a result of either the command or module not being found.
