Question

我正在尝试迁移（更新）这个，但我不断收到此错误消息：

[Symfony \ Component \ Debug \ Exception \ FatalErrorException]语法错误，意外的'＆gt;'，期待'＆lt;'

    Schema::table('products', function (Blueprint $table)) {
        $table->string('XXXX', 50)->change();
        $table->string('XXXX', 50)->change();
        $table->string('XXXX', 10)->change();
        $table->String('XXXX', 100)->change();;
        $table->String('XXXX', 100)->change();
        $table->String('XXXX', 100)->change();
        $table->String('XXXX', 50)->change();
        $table->tinyInteger('XXXX')->unsigned()->change();
        $table->tinyInteger('XXXX')->unsigned()->change();
        $table->String('XXXX', 100)->change();
        $table->tinyInteger('XXXX')->unsigned()->change();
        $table->String('XXXX', 50)->change();
        $table->String('XXXX', 50)->change();
        $table->String('XXXX', 50)->change();
        $table->String('XXXX', 50)->change();
        $table->String('XXXX', 50)->change();
        $table->boolean('XXXX')->change();
        $table->boolean('XXXX')->change();
        $table->boolean('XXXX')->change();
        $table->boolean('XXXX')->change();
        $table->boolean('XXXX')->change();
        $table->boolean('XXXX')->change();
        $table->boolean('XXXX')->change();
        $table->boolean('XXXX')->change();
        $table->boolean('XXXX')->change();
        $table->text('XXXX')->change();
        $table->String('XXXX', 100)->change();
        $table->String('XXXX', 100)->change();
        $table->String('XXXX', 100)->change();
        $table->String('XXXX', 100)->change();
        $table->tinyInteger('XXXX')->unsigned()->change();
        $table->tinyInteger('XXXX')->unsigned()->change();
        $table->tinyInteger('XXXX')->unsigned()->change();
        $table->tinyInteger('XXXX')->unsigned()->change();
        $table->String('XXXX', 50)->change();
        $table->String('XXXX', 50)->change();
        $table->String('XXXX', 50)->change();
        $table->String('XXXX', 50)->change();
        $table->text('XXXX');
        $table->timestamps();
    });
}

Answer 1

您在第5行有;;，String代替string。

顺便说一句，当你运行migrate命令时，你可以从另一个文件（控制器，中间件，帮助器等）中获得错误。

Answer 2

在Laravel Migration Documentation中，它说使用$table->string('XXXX',50);创建VARCHAR等效列。

因此语句$table->String('XXXX', 50)->change();存在语法错误。您应该将所有String更改为string。

PS ：实际上在$table->String('XXXX', 100)->change();;语句中。您使用了;;，但没关系，没有错误会被报告。
