javascript - Webpack 配置不是严格模式，不想更改代码

Question

我尝试构建 BitShares UI 的生产 webpack https://github.com/bitshares/bitshares-ui

问题是 webpack 没有在严格模式下运行但我不想更改代码。有没有办法强制以严格模式解释 webpack 配置，以便我避免此问题？

请检查您的nodejs版本。BitShares-UI 依赖于 Node.js Node ，并且需要版本 8+。在 Ubuntu 和 OSX 上，安装 Node 的最简单方法是使用 Node Version Manager。要安装适用于 Linux/OSX 的 NVM，只需将以下内容复制粘贴到终端中:

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.30.2/install.sh | bash
nvm install v9
nvm use v9

运行后npm run build
