Node-sass 部署到 Heroku 时出错：‘remove_cv’ !std::is_same<数据，std::remove_cv_t>::值>::执行(数据);

Question

我创建了一个 Ruby on Rails 应用程序。它使用 Rails 作为后端和前端。我使用 .scss 文件进行样式设置。

尝试将我的应用程序部署到 Heroku 时出现此错误：

/app/.node-gyp/16.13.1/include/node/v8-internal.h:492:38: error: ‘remove_cv_t’ is not a member of ‘std’
remote:        /app/.node-gyp/16.13.1/include/node/v8-internal.h:492:38: note: suggested alternative: ‘remove_cv’
remote:                     !std::is_same<Data, std::remove_cv_t<T>>::value>::Perform(data);
remote:                                              ^~~~~~~~~~~
remote:                                              remove_cv

已尝试多种方法来解决此问题，但尚未解决。我的 Node 版本是 v14.19.0

我的 package.json 文件：

{
  "name": "Nail_The_Trail",
  "private": true,
  "dependencies": {
    "@rails/actioncable": "^6.0.0",
    "@rails/activestorage": "^6.0.0",

  },

  "devDependencies": {

下面是我的yarn.lock 文件的node-sass 部分（刚刚注意到我的yarn.lock 文件中似乎有两个版本的node-sass...也许这是部分问题）：

我的网站在本地主机上看起来很好，但尝试部署到 Heroku 会出现上面显示的错误。

我相信我目前正在使用yarn和npm，所以这可能是一个部分问题，但不确定这是否是主要问题。另外仅供参考，我最近删除了我的 package-lock.json。

不知道该怎么办这个错误。任何帮助表示赞赏。

这可能与heroku默认提供node 16.x有关，而node-sass不喜欢它，更喜欢14.x；
我可以通过在 package.json 中放入

"engines" : { "node": "14.19.1" },

来使用 14.x ，然后在本地使用该版本 (nvm install 14.19.1 ；nvm 使用 14.19.1），并且在 heroku 上，确保在 ruby​​ 构建包之前添加 Nodejs 构建包（请参阅 https://devcenter.heroku.com/articles/ruby-support#installed-binaries< /a>)，我是这样做的

heroku buildpacks:remove heroku/rails
heroku buildpacks:add heroku/nodejs
heroku buildpacks:add heroku/rails
