node.js - Symfony 5.2 + Webpack Encore：npm 运行显示错误“意外令牌”

Question

我已经设置了一个新项目，并在没有 root 访问权限的共享服务器Symfony 5.2上添加了 Webpack Encore 。

Yarn 在这台机器上不可用，所以我使用了 npm：

// setup new Symfony 5.2 project
symfony new sym5 --version=5.2 --full
...
cd sym5

// add Webpack Encore
composer require symfony/webpack-encore-bundle
npm install
...

// try to compile assets
npm run dev

webpack.config.js我没有对自动创建的和asset/文件进行任何更改。运行npm run dev导致Unexpected token错误：

npm run dev

> @ dev /customers/123/webpages/sym5
> encore dev

/customers/123/webpages/sym5/node_modules/pkg-up/index.js:4
module.exports = async ({cwd} = {}) => findUp('package.json', {cwd});
                       ^

由于我的任何自定义文件中都没有报告错误，我认为这是 Node.js / Webpack 本身的问题？这个对吗？

消息说，应该使用最新版本的 node.js 和 npm。服务器上可用的版本（节点 v6.11.3 和 npm v3.10.10）确实很旧，但没有 root 访问权限我无法更改它，可以吗？

但是，由于使用这些 node.js 和 npm 版本添加/安装 Webpack Encore 没有任何问题，我想知道使用这些旧版本是否真的是问题的原因。

我能做些什么来找到真正的原因并解决问题吗？
