我的脚本抛出了无效的DIRhandle错误

时间：2017-03-27 20:43:14

标签： perl

我的问题是由于某些原因我在运行脚本时遇到两个错误：

  

readdir（）在spreadsheet.pl第206行尝试了无效的dirhandle DIR   closedir（）在spreadsheet.pl第254行尝试了无效的dirhandle DIR。

我的代码

closedir(DIR);`

1 个答案:

答案 0 :(得分：1)

第206和254行是

my @files = readdir(DH);

和

closedir(DH);

此opendir

之后 
opendir(DH, "\/Judging Card\/");

您应该做的第一件事是检查opendir的状态。这将立即告诉您目录句柄无效的原因

喜欢这个

opendir DH, '/Judging Card/' or die qq{Unable to open directory "/Judging Card/": $!};

让我烦恼的第一件事是Judging Card看起来不像根目录名，但是先用斜杠（你不需要在引号内转义斜杠），你说它是在备案系统的根源。但是来自or die的错误消息会告诉您问题
