Question

我正在我的笔记本电脑上工作，它上面有linux mint（版本17）perl 5.18.2。
我运行dbicdump，一切正常。我转储sql数据库并将模式复制到我的PC。
在我的PC linux mint（版本18.1）上安装了perl 5.22.1。我的目录结构和数据库在两台机器上是相同的。在Mint 17的PC架构上没有工作，所以我试图运行dbicdump命令。
当我运行dbicdump时，我得到了

dbicdump Database::Schema dbi:mysql:database=Database 'user' 'password'
Dumping manual schema for Database::Schema to directory . ...
Schema dump completed.
Failed to reload class Database::Schema::Result::Author: sub name "years_rs" is not valid! at /usr/local/share/perl/5.22.1/DBIx/Class /Relationship/Accessor.pm line 99.
Compilation failed in require at (eval 114) line 2.

And all Database::Schema::Result::Author printed in the console.
(not showing becuause of the space it will take)

如果我运行脚本，则显示此错误！

 {UNKNOWN}: sub name "years_rs" is not valid! at /usr/local/share/perl/5.22.1/DBIx/Class/Relationship/Accessor.pm line 99.
Compilation failed in require at /usr/local/share/perl/5.22.1/Class   /C3/Componentised.pm line 150. at /usr/local/share/perl/5.22.1/Class/C3/Componentised.pm line 155

Perl版本5.22.1
DBIx :: Class :: Schema :: Loader（0.07046）
DBIx :: Class（0.82840）

它在perl 5.18.2上工作正常，perl 5.22.1上有错误吗？

我找到了问题的根源，这是外键问题。我发现它与外键有关＆＃39;在数据中。一张表是

 CREATE TABLE `authors` (
`id` INT(50) NOT NULL AUTO_INCREMENT,
`authorName` TINYTEXT NOT NULL,
`aboutAuthor` TINYTEXT NOT NULL,
PRIMARY KEY (`id`)
)
COLLATE='latin1_swedish_ci'  ENGINE=InnoDB  ;

和其他表是

 CREATE TABLE `295c` (
`id` INT(50) NOT NULL AUTO_INCREMENT,
`fileName` VARCHAR(40) NULL DEFAULT NULL,
`file_link` VARCHAR(40) NULL DEFAULT NULL,
`file_toolTips` VARCHAR(40) NULL DEFAULT NULL,
`image` VARCHAR(100) NOT NULL DEFAULT '/img/IconFlag.png',
`content` TEXT NOT NULL,
`author` INT(50) NOT NULL,
`keywords` VARCHAR(80) NULL DEFAULT NULL,
`timemade` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
PRIMARY KEY (`id`),
INDEX `FK__authors` (`author`),
CONSTRAINT `FK__authors` FOREIGN KEY (`author`) REFERENCES `authors`(`id`) )COLLATE='latin1_swedish_ci' ENGINE=InnoDB ;

这些简单的表格给了我错误，
