# I can't make a reference

I'm new to latex so I'm trying to do the vim-latex tutorial. So now I'm supposed to make a reference. My file looks like:

%        File: package.tex
%     Created: Mon Feb 11 07:00 PM 2019 AST

\documentclass[a4paper]{article}

\usepackagei[sublimitis,]{amsmath}

\begin{document}

$$<e^{\pi} + 1 = 0> \label{eqn:euler}$$
This is the famous euler equation. I will type another equation, just as true:
$$\label{eqn:simple} 1 + 1 = 2$$
This is my contribution to mathematics.
This is a reference to (\ref{}).

\end{document}


With the cursor between the {} I pressed in insert mode. I'm supposed to see a list of all the \labels found in my project. But all I got is:

''C:' is not recognized as an internal or external command,
operable program or batch file.


What am I doing wrong?

• This doesn't seem to be related to LaTeX at all. Consider asking at Vim.se. – Johannes_B Feb 18 at 6:38
