LoadError: failed process: Process(`which dvisvgm`, ProcessExited(1)) [1]

Hi, I am using MakieTex to add a TeX formula in my plot's title. However, I came across an error saying # LoadError: failed process: Process(which dvisvgm, ProcessExited(1)) [1]

How can I solve this problem?

BTW, I am using Julia 1.6.1 on MacOS Big Sur

using MakieTeX, CairoMakie

function runge_kutta(t, n_steps,y0)
    k1 = zeros(1, n_steps)
    k2 = k1
    k3 = k1
    k4 = k1
    y = zeros(n_steps+1)
    y[1] = y0

    for ii = 1:n_steps
        k1[ii] = 3 + exp(-t[ii]) - 2 * y[ii]
        k2[ii] = 3 + exp(-(t[ii] + h / 2)) - 2 * (y[ii] + k1[ii] * h / 2)
        k3[ii] = 3 + exp(-(t[ii] + h / 2)) - 2 * (y[ii] + k2[ii] * h / 2)
        k4[ii] = 3 + exp(-(t[ii] + h)) - 2 * (y[ii] + k3[ii] * h)
        y[ii + 1] = y[ii] + h * (k1[ii] + 2 * k2[ii] + 2 * k3[ii] + k4[ii]) / 6
    end
    return y
end

t0 = 0;
tend = 10;
h = .05;
t = t0:h:tend;
n_steps = length(t) - 1;
y0 = 1;

y = runge_kutta(t, n_steps,y0)

fig = Figure()
ax = Axis(fig[1, 1])

lines!(ax, t, y, linewidth=1.5, label="Runge-Kutta Method")

ax.xlabel = "t"
ax.ylabel = "Solution, y(t)"
LTeX(fig[2, 1], raw"{Numerical\ Solutions\ of}: \frac{dy}{dt} + 2 * y - e^{-t} = 3, y_0 = 1")
# LoadError: failed process: Process(`which dvisvgm`, ProcessExited(1)) [1]

The full message is
