Qiskit - MissingOptionalLibraryError pdflatex library is required to use LaTeX circuit drawing

Question

Trying to run below snippet to generate circuit diagram in a Jupyter notebook on Windows.

import qiskit
qc = qiskit.QuantumCircuit(1)
qc.x(0)
qc.draw('latex')

I have install the texlive for windows as mentioned here. Although, this still throws below error trace:

MissingOptionalLibraryError               Traceback (most recent call last)
Input In [2], in <cell line: 4>()
      2 qc = qiskit.QuantumCircuit(1)
      3 qc.x(0)
----> 4 qc.draw('latex')
...
MissingOptionalLibraryError: "The 'pdflatex' library is required to use 'LaTeX circuit drawing'.  You will likely need to install a full LaTeX distribution for your system."

Anything missing?

Answer 1

It seems the executable pdflatex is not in path. You might need to restart your Windows or extend the PATH variable with the pdflatex directory.
