Question

我使用Mongodb Express在MacOS上建立了一个本地主机网站。现在，我要将其部署到Heroku服务器。这是我在遇到错误之前使用的命令

$ git add .
$ git commit -m"Some ms"
$ git push origin master
$ heroku create 
$ git push heroku master

我推送到heroku时的错误是

我尝试了$ npm cache clean --force，$ npm install和$ npm install mongoose --save和$ npm install mongodb --save，但出现此错误

我的package.json文件是

  "version": "1.0.0",
  "description": "Clone of Yelp",

  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",

有人可以帮助我安装猫鼬并部署到Heroku吗？

Answer 1

我通过将package.json中的猫鼬版本从0.0.5更改为^ 4.1.12来解决此错误。我在终端中执行$npm install mongoose --save时得到了0.0.5版。我不知道为什么在使用该命令时会得到这样的版本？

将我的提交推送到heroku时，“代码ETARGET notarget未找到mongodb@0.7.9的匹配版本”
