解释“initializer must be constant”这个错误的含义 “initializer must be constant”这个错误指的是在编程过程中,尝试使用非常量表达式来初始化一个常量或要求为常量的上下文。常量是在编译时就能确定其值的,因此在初始化时只能使用编译时常量表达式。 可能导致这个错误的情况 全局变量或静态变量的初始化:在C语言中,...
initializer must be constant 当你在编写代码时,你可能会遇到一个“initializer must be constant”的错误信息。这是一个常见的编程错误,它出现的原因是你尝试使用一个非常量的值来初始化一个变量。在C++和许多其他编程语言中,一个值被认为是常量,当它在编译时被确定,并且不能在程序运行时被改变。例如,数字3...
In ambient enum declarations member initializer must be constant expression.一个亟待解决的问题 项目:angular2上应用一个简单的ngx-datatable,用angular-cli创建的工程,配置文件package.json将所有包都更新到最新版本(因为之前@angular/compiler-cli4.3.6和typescript2.5.2版本冲突,所以把typescript版本降到了2.3.1)...
