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

-

i'm trying setup display 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!

you need install either xvfb package, or possibly xvfbwrapper:

first check , see if xvfb installed:

xvfb -help

if command not found can install xvfb package following command (or whichever package manager use):

sudo apt-get install xvfb

xvfbwrapper python wrapper running display inside x virtual framebuffer (xvfb).

you can install with:

pip install xvfbwrapper

the error getting seems result of either command or module not being found.

mysql - FireDac error 314 - but DLLs are in program directory -

i getting when trying access mysql database : [firedac][phys][mysql]-314. cannot load vendor library [libmysql.dll or libmysqlld.dll] this did not happen (unchanged) code, however, have upgraded windows 10 , had reinstall delphi xe8, system configuration matter. in order try solve problem, copied both of files c:\windows\sysytem32. when did not seem work, copied them \win32\debug, generated .exe resides. i imagine doing rather stupid, can't see what. the proper solution place driver file (eg., libmysql.dll ) in application's folder, or place installation location in fddrivers.ini file: [mysql] vendor=<folder>\libmysql.dll (recent versions of documentation seem use vendorlib instead of vendor in ini file.) see rad studio documentation topics configuring drivers (firedac) , connect mysql server (firedac) more information.
