tufte-handout citation in vscode

[wzmumu]

I got an error when using the visual studio code extension LaTex Workshop to compile a .tex file with documentclass tufte-handout.

A tufte style .tex file with documentclass tufte-handout works well in other IDEs, e.g., texstudio. Other style .tex file with documentclass such as article or revtex, can also be compiled successfully using LaTex Workshop. But an error occurs when I combine them.

The error may come from citations. When I do not use any \cite command, the error messages are:

• I found no \citation commands
• I found no \bibdata command
• I found no \bibstyle command
  When I add a \cite command, the error messages is:
• Undefined control sequence.
