what's the version of Node.js are you using?

I ran into the same error when I was running the latest terser-webpack-plugin @ 3.0.2. According to the release log, there were some breaking changes introduced in 3.0.0 and one of them was "minimum supported Node.js version is 10.13"

It worked when I downgraded terser-webpack-plugin to 2.3.6.

So you'll probably have to upgrade your Node.js if you're using a version earlier than 10.13, or downgrade your terser-webpack-plugin.

您使用的是什么版本的 Node.js？
我在运行最新的 terser-webpack-plugin @ 3.0.2 时遇到了同样的错误。根据发布日志，在 3.0.0 中引入了一些重大更改，其中之一是“最低支持的 Node.js 版本为 10.13”
当我将 terser-webpack-plugin 降级到 2.3.6 时，它起作用了。
因此，如果您使用的是 10.13 之前的版本，您可能必须升级您的 Node.js，或者降级您的 terser-webpack-plugin。
