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))

    self._obj = self.display_class(

    ubuntu_package=PACKAGE).check_installed()
  File "/usr/lib/python2.6/site-packages/easyprocess/__init__.py", line 209, in check_installed
    raise EasyProcessCheckInstalledError(self)

Program install error!

Answer 1

您可能需要安装xvfb软件包,或者可能需要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xvfb使用以下命令(或通常使用的软件包管理器)安装软件包:

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.

我在 Mac 上遇到了这个错误，并（最终）通过安装 Xquartz 解决了它： https: //www.xquartz.org/（安装后重新启动！）
