我可以使用Google Closure编译器编译SJCL库吗? [英] Can I compile SJCL library with Google closure compiler?

问题描述

我有一个使用Closure Compiler v20181210进行编译和精简的普通javascript项目.我想在该项目中使用SJCL进行加密.

I have a vanilla javascript project that is compiled and minified using Closure Compiler v20181210. I want to use SJCL in that project for crypto.

我将此文件复制到我自己的项目中，并使用该库编写了代码.但是，当我尝试编译它时，Closure Compiler从库中抛出了一系列错误(粘贴在下面).

I copied this file into my own project and wrote code using the library. But when I try to compile it, Closure Compiler throws a bunch of errors from the library (pasted below).

在SJCL网站上，该文件表示使用Google Closure Compressor压缩了文件.所以我想它应该与Closure兼容?为什么不编译呢?

On the SJCL website, it says that the file is compressed using Google Closure Compressor. So I imagine it should be compatible with Closure? Why is it not compiling then?

我还读了一些关于externs的文章.但是我希望所有代码都在一个缩小的文件中.使用externs，看来我需要SJCL的另一个导入.

Also, I read about externs. But I want all the code to be in a single minified file. With externs, it looks like I would need another import for SJCL.

一些Closure编译器错误:

Some of the Closure Compiler Errors:

ERROR - cannot instantiate non-constructor

我正在使用所有这些args运行Closure编译器.当我删除它们时，项目将编译.但是我不确定是否可以安全地删除这些文件?

I am running Closure compiler with all these args. When I remove them, the project compiles. But I am not sure if its safe to remove these?

推荐答案

由于我为自己的项目设置了jscomp_error标志，因此Closure编译器向SJCL抛出错误.没有这些，sjcl.js可以很好地编译.

Closure Compiler was throwing errors for SJCL because of the jscomp_error flags I had on for my own project. Without these, sjcl.js compiles fine.

我通过添加--hide_warnings_for='sjcl.js'

因此，项目的其余部分仍然使用这些标志，但是sjcl可以很好地编译.

So the rest of the project still uses those flags but sjcl compiles fine.
