SyntaxError：意外令牌|在Centos 7.6上为canvas-lms安装带有纱线的webpack acorn.js软件包时出错

问题描述

如果我输入的内容不正确，请更正我的问题标题或术语，因为我不太会使用Ruby，Node或Yarn。

我正在Canvas-lms VPS上从源代码安装Centos 7.6（SELinux未强制执行）。我已经安装了核心操作系统依赖项，并在最后的命令中通过yarn安装了Canvas-lms应用。

命令是：

bundle exec rake canvas:compile_assets —trace

我相信/public/dist/webpack-production/目录中有错误的地方引用的文件是为安装Webpack所需的软件包而构建的临时文件。我查看了这些文件，并将引用的代码部分放在底部。两者都来自acorn.js包。

我在另一个线程中读到，这可能是由malforned-JSON引起的，或者可能是由于链接断开或链接中的type-o引起的。这可能是软件包安装程序中的错误，因此应该由维护软件包存储库的人员解决？

如果我能找到解决问题的正确方法，并且如果我无法获得按钮式的解决方案，那么我会很乐于助您一臂之力。
