Heroku推送-ExecJS :: RuntimeError:SyntaxError:预期名称 [英] Heroku push - ExecJS::RuntimeError: SyntaxError: Name expected

问题描述

推送到Heroku时遇到以下错误.前几天工作正常.我尝试推送的提交没有重大配置更改.我很困惑如何解决此问题. Rails 5.1应用程序使用以下构建包:

I am encountering the following error when pushing to Heroku. Was working fine the other day. No major configuration changes on the commit I'm trying to push. I'm stumped at how to troubleshoot this. The Rails 5.1 application uses the following buildpacks:

1. heroku/nodejs
2. heroku/ruby

我正在使用卷筒纸和纱线.我认为这与它有关，但是在挖掘更多信息时遇到了麻烦.

I'm making use of webpacker and yarn. I think that has something to do with it but having trouble digging for more information.

经进一步研究，发现该问题与Uglifier有关.当我将第三方库datepicker.js的内容复制并粘贴到Uglifier中时，会出现相同的错误:

Upon further research, discovered the problem to be related to Uglifier. When I copy and paste the contents of third party library datepicker.js into Uglifier I get the same error:

> Uglifier.compile( <<< file contents >>> )
ExecJS::RuntimeError: SyntaxError: Name expected
from JS_Parse_Error.get ((execjs):3538:621)

推荐答案

我发现，此问题的原因与Uglifier尝试处理名为js-datepicker(datepicker.js)的第三方库时可能的错误有关. ).我在Uglifier Github上打开了一个问题: https://github.com/lautis/uglifier/Issues/124

I discovered that the cause of this issue is related to a possible bug in Uglifier when it tries to process a third party library named js-datepicker (datepicker.js). I opened up an issue on the Uglifier Github: https://github.com/lautis/uglifier/issues/124

通过在我的app/assets/javascripts/application.js文件中包含缩小的js-datepicker，我找到了解决此问题的方法.

I figured out a workaround for this by including the minified js-datepicker in my app/assets/javascripts/application.js file like this.

//= require js-datepicker/datepicker.min
