Heroku create-react-app部署Uncaught SyntaxError:意外令牌< [英] Heroku create-react-app deploy Uncaught SyntaxError: Unexpected token <
问题描述
每当我使用create-react-app buildpack部署heroku应用程序时，第一次尝试访问我的域时，加载的页面都是白色的，并且开发者控制台中显示错误
Whenever I deploy my heroku app with the create-react-app buildpack, the first time I try to access my domain, the page loaded is white and there is an error in the developer console saying
Uncaught SyntaxError: Unexpected token <
在文件 main.6396d38a.js:1 中，该文件由react版本生成.但是，当我刷新页面时，该网站运行正常.是否有可能发生这种情况?我尝试使用 npm run build 和 serve -s build 在我的 localhost 上复制错误，但是我的网站在那儿工作得很好.为什么每次响应部署到heroku之后仅显示一次?
in the file main.6396d38a.js:1 which is generated by the react build. However, when I refresh the page, the website works perfectly fine. Is there a reason this could be happening? I tried to replicate the error on my localhost using npm run build, and serve -s build but my website works perfectly fine there. Why would this only show up once after every react deploy to heroku?
我的package.json有一个与我的网站域名相关联的首页(不是.herokuapp.com)
My package.json has a homepage associated with the domain name of my website (not .herokuapp.com)
主页":"https://www.example.com/"
推荐答案
在您的 package.json 内，确保您的 homepage URL正确:
Inside your package.json make sure your homepage URL is correct:
"homepage": "https://app.herokuapp.com/"
更新
进一步的调查表明这是一个缓存问题.清除Cookie，网站内容和DNS可解决此问题.
Update
Further investigation shows this was a caching issue. Clearing cookies, website content, and DNS fixed the issue.
