javascript - toLocaleDateString 返回字符串而不关心语言环境

Question

我正在使用 Discord.js 在 NodeJS 中开发一个 Discord 机器人，我想解析格式为“YYYY-MM-DD”的日期并以长 fr-FR 格式显示。

我试过了:

var dateSortie = new Date("2018-06-03");
var options = {
  weekday: 'long',
  year: 'numeric',
  month: 'long',
  day: 'numeric'
};
console.log(dateSortie.toLocaleDateString("fr-FR", options));

无论语言环境如何(fr-Fr、de-De、...)，它总是返回 "2018 M06 3, Sun"。

采购自 this GitHub 问题:

By default --with-intl=small-icu is used to build node, which contains just the en-US locale [...]. You will need to either build node with --with-intl=full-icu or --with-intl=system-icu if you want to be able to use more locales. The reason node is built with a smaller ICU by default is file size.

除了构建您自己的 Node 版本之外，另一种方法似乎是安装 full-icu模块。
