无法在 Heroku 中安装节点

Question

我正在尝试使用节点和 npm 安装在 Heroku 上部署 Django 应用程序，但是，在部署应用程序时，我在 Heroku 控制台上收到以下错误：

 npm ERR! node v11.13.0
       npm ERR! npm  v2.15.12
       npm ERR! path /tmp/build_number/node_modules/.bin/grunt
       npm ERR! code ENOENT
       npm ERR! errno -2
       npm ERR! syscall unlink

       npm ERR! enoent ENOENT: no such file or directory, unlink '/tmp/build_number/node_modules/.bin/grunt'
       npm ERR! enoent This is most likely not a problem with npm itself
       npm ERR! enoent and is related to npm not being able to find a file.
       npm ERR! enoent 

       npm ERR! Please include the following file with any support request:
       npm ERR!     /tmp/build_number/npm-debug.log
-----> Build failed

我正在尝试使用使用构建包的 Vue.js 组件构建图表。我想知道如何在 Heroku 上安装 npm。任何帮助将不胜感激。

我的网站配置如下：

Django 版本：2.1.7 节点版本：11.3.0 Python版本：3.7.3

我的 package.json 文件如下所示：

Heroku 默认启用了 Node 模块缓存。因此，当您尝试对 package.json 进行更改时，Heroku 无法识别您对 devDependencies 所做的更改。按照以下两个步骤，您应该能够部署它：

从您的 devDependencies 中删除 grunt-cli
运行这个命令禁用缓存

heroku config:set NODE_MODULES_CACHE=false
部署您的代码
