当我试图导入material-components-web/material-components-web (我已经安装了npm)时,通过SASS我得到了一个错误,告诉我这个文件是找不到的或者是不可读的。
我在主App.vue文件中进行了导入:
<style lang="sass">
@import "material-components-web/material-components-web"
</style>目录如下:
node_modules/
(lots of packages)
@material/
(lots of material components)
material-components-web/
material-components-web.scss
src/
App.vue
main.js
index.html
package.json
webpack.config.js我第一次尝试修复这个:
显然,我首先想的是,路径是不正确的,并且尝试导入../node_modules/material-components-web/material-components,这是一种工作。然而,material-components-web也在导入一些东西(每个单独的材料组件都来自@material)。因此,即使加载了material-components-web,它还是会崩溃的。
我还在material-components-web的vue示例的源代码中看到,他们只是在导入material-components-web/material-components,而不是../node_modules/material-components-web/material-components,所以问题必须发生在其他地方。
于是我绊倒了一些有类似问题的人。他们都被告知在webpack配置中实现如下内容:
{
loader: 'sass-loader',
options: {
sourceMap: true,
includePaths: glob.sync('packages/*/node_modules').map((d) => path.join(__dirname, d)),
},
}我也试过了。没起作用。我克隆了vue-示例的材料-组件-网络,这也令人震惊地没有工作。(虽然它应该有效,对吗?我是说这是官方的例子)
所以我的问题是:这是个虫子吗?如果不是我做错了什么?
这里有一些更多的代码来获得一个概述:

我遇到了这个问题,我的解决方案是,我从一个子文件夹导入了配置的一部分,这导致@import试图从包含我配置的子文件夹下的一个不存在的node_modules文件夹导入‘@material/按钮/mdc-按钮’。在webpack构建错误中,请看一下它试图导入的路径。你的scss装载机会在呕吐时打印出来。

我也有过类似的问题。从错误中可以看出,Webpack试图从与.vue文件相同的目录中导入这些文件。我的解决方案是修改webpack配置,以包括node_modules文件夹。然而,如何做到这一点还不清楚。
对于Vue CLI,您可以从vue.config.js文件中执行如下操作:
module.exports = {
// ... other settings ...
configureWebpack: {
module: {
rules: [
{
test: /\.scss$/,
use: [
{
loader: 'sass-loader',
options: {
includePaths: ['node_modules']
}
}
]
}
]
}
}
