下面的问题似乎只发生在Spyder IDE上，当我从命令行运行脚本时，它不会发生。
尝试在Python 2.7.12中使用pyplot绘制一个简单的图|Anaconda自定义（64位）|：
import matplotlib.pyplot as plt
plt.plot(x,y)我收到了以下信息：
sh: 1: dvipng: not found

请确保第一个
dvipng安装在spyder外部。这可以通过以下方式完成。在unix系统（Mac OSX、LINUX）上，请转到终端，并输入（Windows power shell中提供了类似的命令）。此命令将
1.返回一个错误，在这种情况下，您必须首先安装
dvipng，安装过程完全取决于您的操作系统或
1.返回路径，例如
/usr/bin/texlive/dvipng（确切路径可能会有所不同）。如果是1.，安装
dvipng。这可能会解决您的问题。如果不是，请转到说明的开头。如果您已经安装了dvipng，您将在2.中结束。如果2.，则从
