我收到了奇怪的错误pgfplotstable：
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{pgfplots}
\pgfplotsset{compat=1.7}
\usepackage{pgfplotstable}
\begin{document}
\pgfplotstabletypesetfile[columns={lambda,n},col sep=comma]{n.csv}
\end{document}
以及n.csv文件：
lambda,n
6907.16,1.4190
6716.17,1.4185
5790.65,1.4252
5769.59,1.4256
5460.74,1.4272
4916.04,1.4345
4358.35,1.4412
4347.50,1.4461
4339.24,1.4475
4077.81,1.4555
4046.56,1.4572
它出什么问题了：
