如何在Mac下的perl中刷新文件？
我在远程 iMac 中有为 darwin-thread-multi-2level 构建的 perl v5.10.0。我想运行一些 perl 脚本，该脚本打印一些数据并在每行输出后刷新。
- $file_handle->flush();
- 自动刷新$file_handle；
我已经在文件顶部使用 use IO::Handle; 尝试过这两个版本，但我得到的结果是 Can't located object method "autoflush" via package "FileHandle “。
I have perl, v5.10.0 built for darwin-thread-multi-2level in remote iMac. And I want to run some perl script which prints to file some data and flushes after each line of output.
- $file_handle->flush();
- autoflush $file_handle;
I have tried this two versions with use IO::Handle; in top of the file, but the result I'm getting is Can't locate object method "autoflush" via package "FileHandle".

您从哪里获取
$file_handle？看起来它是一个 FileHandle 实例，而不是 IO::Handle 对象。您可以
在脚本的顶部尝试，而不是
IO::Handle。或者，更改您的代码，使$file_handle不再是FileHandle实例。PS：你真的不应该运行 5.10.0，它有很多错误。 5.10.1 或更新的版本要好得多。
Where are you getting your
$file_handlefrom? Looks like it's aFileHandleinstance, not anIO::Handleobject.You could try
at the top of the script, instead of
IO::Handle. Alternatively, change your code so that$file_handleis no longer aFileHandleinstance.PS: you really shouldn't be running 5.10.0, it's got quite a few bugs. 5.10.1 or anything newer is a lot better.
您确定“use IO::Handle;”吗？没有错别字吗？
在我看来该模块尚未加载。
Are you sure the "use IO::Handle;" doesn't have a typo?
It looks to me like the module hasn't loaded.
使用文件句柄；解决了我的问题。我在使用 Net::SCP::Expect 时遇到问题。这发生在 CentOS 6.3 下。
我收到如下错误：
-无法通过包文件句柄找到对象方法自动刷新
- 无法通过包文件句柄定位对象方法阻塞
use FileHandle; solved my issue. I was having issues with Net::SCP::Expect. This happened under CentOS 6.3.
I was getting errors like:
-can't locate object method autoflush via package filehandle
-can't locate object method blocking via package filehandle
