MikTeX 2.9 报错Could not open the file Definitions/logo-mdpi-eps-converted-to.pdf

MikTeX 2.9 使用问题的记录（1）

部分相关错误信息如下：

---

MiKTeX GPL Ghostscript 9.25: **** Could not open the file Definitions/logo-mdpi-eps-converted-to.pdf .
**** Unable to open the initial device, quitting.

Sorry, but “MiKTeX EPS-to-PDF Converter” did not succeed.

The log file hopefully contains the information to get MiKTeX going again:

C:\Users\somebody\AppData\Local\MiKTeX\2.9\miktex\log\epstopdf.log

geometry detected driver: pdftex

! Package pdftex.def Error: File `Definitions/logo-mdpi-eps-converted-to.pdf’ n
ot found: using draft setting.

See the pdftex.def package documentation for explanation.
Type H for immediate help.

l.132 \begin{document}

我在这里还有这里找到了解决方法：
在错误报告中，找到原文l.132 \begin{document}对应的那一行，在它之前加上\epstopdfsetup{outdir=./}，成功解决了问题。
