闭包编译器-{SyntheticVarsDeclar}:警告-重新声明的变量 [英] Closure Compiler - {SyntheticVarsDeclar}: WARNING - Redeclared variable

问题描述

我正在使用--warning_level=VERBOSE和--compilation_level ADVANCED_OPTIMIZATIONS

它输出:

{SyntheticVarsDeclar}: WARNING - Redeclared variable: i
0 error(s), 1 warning(s)

是否可以找到有关此i变量声明位置的更多信息?

Is there a way to find out more information about where this i variable is declared?

//更新

我已经遍历了所有文件中的每个i变量，没有一个被重新声明.

I have run through every i variable in all the files and there is none that are redeclared.

以下是正在使用的标志的列表:

Here is a list of flags being used:

--jscomp_off=externsValidation

--summary_detail_level=3

--warning_level=VERBOSE

--externs

--compilation_level ADVANCED_OPTIMIZATIONS

--output_wrapper

--source_map_format

--js_output_file

//更新2

我正在使用以下最新的Closure Compiler: http://dl.google.com/closure-compiler/compiler-latest.zip

I am using the latest Closure Compiler from: http://dl.google.com/closure-compiler/compiler-latest.zip

当我在第一个文件的顶部添加"var i"时，编译器将返回:

When I add a "var i" at the top of the first file, the compiler comes back with:

firstFile.js:1: WARNING - Redeclared variable: i
var i;
    ^

，并且之前没有{SyntheticVarsDeclar}警告.

and there is no previous {SyntheticVarsDeclar} warning.

推荐答案

验证是否未使用--third_party标志.除非缺少声明，否则什么都不能添加为{SyntheticVarsDeclar}. --third_party标志导致缺少的全局变量声明在"{SyntheticVarsDeclar}"中声明".

Verify that the --third_party flag is not being used. Nothing should be added as {SyntheticVarsDeclar} unless the declaration is missing. The --third_party flag cause missing global variables declarations to be "declared" in "{SyntheticVarsDeclar}".
