流星更新不更新heroku上的节点版本

Question

我最近更新流星版本为1.6，该应用在本地工作正常。但是当我把它推到heroku时，它坠毁了。我试图调试并发现正在使用的节点版本是4.7，而应该升级到8.8。

我创建了一个新的heroku应用程序，并推送相同的代码，它安装了8.8.1版本的节点，并且该应用程序工作正常。

我正在使用meteor-build-pack在heroku上部署。我试图部署具有详细选项的应用程序，并得到了以下的输出：

我同时推到新的应用程序（这和预期一样）得到的输出如下：

任何帮助将不胜感激。提前致谢！

以下解决方案适用于我。

我删除了buildpack并重新创建它。

heroku buildpacks:clear --app appName 
heroku buildpacks:set https://github.com/AdmitHub/meteor-buildpack-horse.git --app appName 

然后我将NODE_VERSION设置为heroku的配置变量为我想要的版本。

heroku config:set NODE_VERSION=8.8.1 --app appName 

之后，部署工作正常。
