使用 Postcss 的 Webpack 编译失败，因为在 node_modules 的库中找不到 scss 文件
Webpack Compilation with Postcss fail because not find scss file in library in node_modules
这是我的项目结构：
node_modules
dist
config
- webpack.common.js
- webpack.dev.js
- webpack.prod.js
- webpack.test.js
src
- app
- app-routing.module.ts
- app.component.html
- app.component.scss
- app.component.ts
- app.module.ts
- index.ts
- index.html
- main.browser.ts
- polyfills.browser.ts
angular.json
package.json
postcss.config.js
tsconfig.json
tsconfig.webpack.json
webpack.config.js
当我尝试使用 yarn 编译或构建项目时，它失败了，因为它在 node_modules:
中找不到 scss 文件
其实scss文件存在：
文件属于angularflex layout
下面是试图使用属于 @angular/flex-layout/mq
的 layout-bp 的 app.components.scss
@import '@angular/flex-layout/mq';
.top-bar {
height: 25px;
width: 100%;
}
.start-over {
font-weight: bold;
border-radius: 2.5px;
.material-icons {
margin-right: 5px;
transform: scalex(-1);
}
span {
font-size: 13px;
vertical-align: middle;
}
&--mobile {
display: none;
.material-icons {
transform: scalex(-1) translate(12px, -12px);
}
}
}
@media screen {
@each $br in ('xs', 'sm') {
@include layout-bp($br) {
.start-over {
margin-right: 8px;
}
}
}
}
我认为问题是因为它试图在 src/app/ 中找到 mq.scss 文件，而文件位于 node_modules
到运行我使用的项目yarn start:consumer或yarn start
此命令执行以下操作：
1) 构建项目。
2) 运行 dist 文件夹中的文件：node dist/app.js

就像我在问题中所说的那样，问题是编译器在尝试从 node_modules 导入 scss 文件时无法编译组件的 scss 文件。
我通过 sass-loader 在 webpack.config.common.js:
中为 scss 应用以下规则解决了这个问题
{
test: /\.component\.(css|sass|scss)$/,
use: [
'to-string-loader',
'css-loader',
'postcss-loader',
{
loader: 'sass-loader',
options: {
sassOptions: {
importer: url => {
if (url.startsWith('@angular/')) {
return {
file: path.resolve(`./node_modules/${url}`),
};
}
return null;
},
},
}
}
]
}
如果我必须从 node_module 导入另一个库，我应该添加另一个 else if 语句：
例如，假设我在 node_modules 中有一个自定义库 my-library 并且我想访问：node_modules/my-library/style.scss 所以我必须添加以下 else if 语句：
{
test: /\.component\.(css|sass|scss)$/,
use: [
'to-string-loader',
'css-loader',
'postcss-loader',
{
loader: 'sass-loader',
options: {
sassOptions: {
importer: url => {
if (url.startsWith('@angular/')) {
return {
file: path.resolve(`./node_modules/${url}`),
};
else if (url.startsWith('my-library/')) {
return {
file: path.resolve(`./node_modules/${url}`),
};
}
return null;
},
},
}
}
]
}
这样，我的项目又可以运行了。它还使用 build 和 serve.
编译
最后，在我的postcss.config.js中我只需要：
module.exports = {
plugins: [
require('autoprefixer')
]
}
这是我的项目结构：
node_modules
dist
config
- webpack.common.js
- webpack.dev.js
- webpack.prod.js
- webpack.test.js
src
- app
- app-routing.module.ts
- app.component.html
- app.component.scss
- app.component.ts
- app.module.ts
- index.ts
- index.html
- main.browser.ts
- polyfills.browser.ts
angular.json
package.json
postcss.config.js
tsconfig.json
tsconfig.webpack.json
webpack.config.js
当我尝试使用 yarn 编译或构建项目时，它失败了，因为它在 node_modules:
中找不到 scss 文件其实scss文件存在：
文件属于angularflex layout
下面是试图使用属于 @angular/flex-layout/mq
layout-bp 的 app.components.scss
@import '@angular/flex-layout/mq';
.top-bar {
height: 25px;
width: 100%;
}
.start-over {
font-weight: bold;
border-radius: 2.5px;
.material-icons {
margin-right: 5px;
transform: scalex(-1);
}
span {
font-size: 13px;
vertical-align: middle;
}
&--mobile {
display: none;
.material-icons {
transform: scalex(-1) translate(12px, -12px);
}
}
}
@media screen {
@each $br in ('xs', 'sm') {
@include layout-bp($br) {
.start-over {
margin-right: 8px;
}
}
}
}
我认为问题是因为它试图在 src/app/ 中找到 mq.scss 文件，而文件位于 node_modules
到运行我使用的项目yarn start:consumer或yarn start
此命令执行以下操作：
1) 构建项目。
2) 运行 dist 文件夹中的文件：node dist/app.js

就像我在问题中所说的那样，问题是编译器在尝试从 node_modules 导入 scss 文件时无法编译组件的 scss 文件。
我通过 sass-loader 在 webpack.config.common.js:
scss 应用以下规则解决了这个问题
{
test: /\.component\.(css|sass|scss)$/,
use: [
'to-string-loader',
'css-loader',
'postcss-loader',
{
loader: 'sass-loader',
options: {
sassOptions: {
importer: url => {
if (url.startsWith('@angular/')) {
return {
file: path.resolve(`./node_modules/${url}`),
};
}
return null;
},
},
}
}
]
}
如果我必须从 node_module 导入另一个库，我应该添加另一个 else if 语句：
例如，假设我在 node_modules 中有一个自定义库 my-library 并且我想访问：node_modules/my-library/style.scss 所以我必须添加以下 else if 语句：
{
test: /\.component\.(css|sass|scss)$/,
use: [
'to-string-loader',
'css-loader',
'postcss-loader',
{
loader: 'sass-loader',
options: {
sassOptions: {
importer: url => {
if (url.startsWith('@angular/')) {
return {
file: path.resolve(`./node_modules/${url}`),
};
else if (url.startsWith('my-library/')) {
return {
file: path.resolve(`./node_modules/${url}`),
};
}
return null;
},
},
}
}
]
}
这样，我的项目又可以运行了。它还使用 build 和 serve.
最后，在我的postcss.config.js中我只需要：
module.exports = {
plugins: [
require('autoprefixer')
]
}
