RuntimeError: latex not found

[OrangeAoo]

I have had the package installed, and just tested the sample codes in README. But an error arised:

Tested code:

latex_str=r'$\sin(x) = \sum_{n=0}^{\infty} \dots$'
out = latex2svg(latex_str)
print(out['valign'])  # baseline offset in em
print(out['svg'])  # rendered SVG

Error info:
