IOError: File YAHOO-INDEX_GSPC.csv does not exist

虽然文件存在于该位置

，但仍会出现IO错误

IO ERROR occurs at compile time 为什么它在其他IDLE pandas模块中找不到，但在Spyder中没有pandas Error

Answer 1

.csv文件的路径是相对的。如果文件不在您当前的工作目录中，python将无法找到它。

“虽然文件存在于该位置”......这是相对路径的问题：那个位置是什么？

这是一个应该解决问题的先前答案： Python ConfigParser cannot search .ini file correctly (Ubuntu 14, Python 3.4)

IO错误：虽然csv文件存在于指定的给定位置，但它不存在
