Vue + Webpack 构建显示空白页面
Vue + Webpack build show blank page
我在使用 vue 应用程序 + webpack 时遇到了一些问题。当我 运行 npm 运行 dev 一切顺利。当我进入生产模式时,npm 运行 构建,构建过程完成。但是当我打开 dist index.html 或将带有 index.html 的捆绑包复制到共享主机 public_html 文件夹时,它只显示空白。
以下是我的设置:

抱歉,如果我无法显示任何进一步的代码,谢谢。
我假设您 运行 您的作品位于根项目文件夹的子目录中,例如http://example.com/folder
.
如果您的项目位于 folder
子目录中,则需要为 build
属性 配置 config/index.js
中的 assetsPublicPath
。
示例:
build: {
assetsPublicPath: '/folder/'
}
此外,您的路由文件应将 base
属性 设置为:
export default new VueRouter({
base: '/folder/'
})
查看更多here.
从您那里收集到更多数据后,可能是您主机上的配置加载了错误的页面。
对于 Apache,您的 Alias
或 vhost
应该指向 dist
目录。例如(我自己的用例)
Alias /foo /var/www/htdocs/foo/dist
在我的例子中,我所要做的就是在 router.js
中添加一个重定向
{
path: "/index.html",
redirect: "/"
}
在我使用 <template>
的场景中,我必须在 vue.config.js
.
中启用 runtimeCompiler
这对我有用:在 router/index.js 中添加
{
path: '*',
name: 'catchAll',
component: Home
}
在路径的尽头
我遇到了同样的问题。我找到了一个解决方案(我想它就在这里,但我不记得也找不到了)。解决方案是在 vue.config.js:
中显式声明 publicPath 变量
module.exports = {
publicPath: "",
chainWebpack: config => {
config.plugin("html").tap(args => {
args[0].title = "My Vue App";
return args;
});
}
};
它有效,但我想知道 为什么 它有效,所以我进行了一些挖掘,在 vue-cli documentation 中,我了解到 publicPath 变量指示 BASE_URL 环境变量。它默认为“/”,因此如果您 运行 您的 Vue 应用程序位于根目录中,则没有必要。但是,如果像我在我的项目中所做的那样,您 运行 它来自 domain.com/appdir/index.html 之类的子目录,它将显示一个空白页面,因为它正在尝试从中提取内容“/”路径(例如:domain.com/)
我在使用 vue 应用程序 + webpack 时遇到了一些问题。当我 运行 npm 运行 dev 一切顺利。当我进入生产模式时,npm 运行 构建,构建过程完成。但是当我打开 dist index.html 或将带有 index.html 的捆绑包复制到共享主机 public_html 文件夹时,它只显示空白。
