【问题描述】:
我已经成功注册 Heroku,但是当我 git push 并运行 app 时,它显示
Application error. An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details. You can do this from the Heroku CLI with the command
然后,我从 Web 浏览器转到 Heroku,在“手动部署”下,单击“部署分支”并得到以下错误列表:
-----> Node.js app detected

! Outdated Yarn lockfile
Your application contains a Yarn lockfile (yarn.lock) which does not
match the dependencies in package.json. This can happen if you use npm
to install or update a dependency instead of Yarn.
Please run the following command in your application directory and check
in the new yarn.lock file:
$ yarn install
$ git add yarn.lock
$ git commit -m "Updated Yarn lockfile"
$ git push heroku master

谁能给我一些建议?我不知道为什么它提到纱线。这是我的 package.json:
