当我使用
npm start
运行我的开发服务器时,我的应用程序在 http://localhost:3000/ 中完美运行。但是,当我 npm run build
和 firebase deploy
应用程序时,该应用程序未运行并抛出错误:未捕获的语法错误:意外的令牌'<'.
找到我的 firebase.json:
{
"functions": {
"predeploy": [
"npm --prefix \"$RESOURCE_DIR\" run lint"
]
},
"hosting": {
"public": "build",
"ignore": [
"firebase.json",
"**/.*",
"**/node_modules/**"
],
"rewrites": [
{
"source": "**",
"destination": "/index.html"
}
]
}
}
我尝试添加此内容,以防某些内容被捕获但没有成功:
"headers": [
{
"source" : "/sw.js",
"headers" : [
{
"key" : "Cache-Control",
"value" : "no-store"
}
]
}
]
还有我的package.json:

"name": "marioplan",
"version": "0.1.0",
"private": true,
"dependencies": {
"@testing-library/jest-dom": "^5.11.6",

}
}
我阅读了一些内容并进行了有关需要在 packaje.jason 中指定的 '“homepage”:' 的试验,因为
npm run build
抛出:
该项目是假设其托管在 / 上构建的。 您可以使用 package.json 中的主页字段来控制它。
我还尝试删除
npm --prefix \"$RESOURCE_DIR\" run lint
predeploy 命令,因为我不清楚它的作用,也没有不同的结果。
以防万一有人可能想知道,我会检查这些文件是否实际部署在 firebase 托管控制台中。
您不提供任何 JavaScript,而是 HTML,这就是意外的
<
的来源。我会责怪这个重写规则,它提供了“有限”的意义,因为它总是有用的index.html
:
"rewrites": [
{
"source": "**",
"destination": "/index.html"
}
]
解决方案(至少在我的例子中)是构建项目,然后将其部署到 firebase 托管
npm run build
然后
firebase deploy
