Question

我正在尝试在具有节点和npm安装的Heroku上部署Django应用程序，但是，在部署该应用程序时，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buildpacks的Vue.js组件来构建图表。我想知道如何在Heroku上安装npm。任何帮助将不胜感激。

我对网站具有以下配置：

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默认情况下启用了Node模块缓存。因此，当您尝试对package.json进行更改时，Heroku无法识别对devDependencies的更改。请遵循以下两个步骤，您应该可以部署它：

从devDependencies中删除grunt-cli
运行此命令以禁用缓存

heroku config:set NODE_MODULES_CACHE=false
部署代码

无法在Heroku中安装节点
