라텍스에서 tikzpicture를 사용하는 동안 인식할 수 없는 명령

Question

피라미드 그림을 컴파일하는 동안 인식할 수 없는 명령 팝업이 나타납니까? 이유는 무엇이며 어떻게 해결할 수 있나요?

제발, 아래 사진을 참조하세요:

\begin{figure}[!h]
    \centering
\tikzset{tri/.style={%
                        regular polygon,

                        minimum size=#1,
                        draw,
                        thick,
                        anchor=north
                    },
                    ptext/.style={font=\bfseries,align=center,text width=0.8*\pyrsize}
        }

    \NewDocumentCommand{\pyramid}{sO{}mm}{% #3 size; #4 entries
    \begin{tikzpicture}

        \coordinate (T) at (0,0);
        \foreach \test/\testi [count=\testnum from 1] in {#4}{\xdef\tot{\testnum}}%
        \pgfmathsetmacro{\incr}{#3/\tot}
        \foreach \step/\col [count=\stepnum from 0] in {#4}{%
            \pgfmathsetlengthmacro{\pyrsize}{#3-\incrrate*\stepnum*\incr}

            \pgfmathsetlengthmacro{\lift}{0.0*\incr*\incrrate}% raise text in top shape
            \else
            \pgfmathsetlengthmacro{\lift}{0.1*\incr*\incrrate}% raise text in remaining shapes
            \fi
            \node[above=\lift of T\stepnum.south,ptext] {\step\strut};
