I am facing a weird error when I installed Bootstrap. The error is below. I tried uninstalling less-loader and installing less-loader@5.0.0, because I saw it online, but it did nothing. I am unsure what to do at this step.
Syntax Error: TypeError: this.getOptions is not a function

Similar to what @KostDM said, in my case it seems like sass-loader@11.0.0
doesn't work with vue@2.6.12
.
I installed sass-loader@10.1.1
and it worked like a charm again.
In your package.json
:
"sass-loader": "^10",
I had the same problem resolved by downgrading sass-loader to 10.1.1. I am using @vue/cli 4.5.8 that includes webpack@4.46.0.
From v11.0.0 of sass-loader and v8.0.0 of less-loader, the
minimum supported webpack version is 5
sass-loader v11.0.0 release notes
less-loader v8.0.0 release notes
Downgrading the sass-loader to ^10.0.0 worked for me, but on a fresh Nuxt.js CLI application I had to also install Sass with:
npm i sass
To downgrade, you can remove the node_modules
folder and to add, run this in your terminal:
npm i sass-loader@10
This will install the newest 10 version of sass-loader.
And after all, again install all dependencies:
npm i
EDIT
Sass-loader versions higher than 10 requires webpack 5
For me it helped to downgrade postcss-loader
+ "postcss-loader": "^4.2.0",
- "postcss-loader": "^5.0.0",
Yesterday I found a problem after upgrading sass-loader to the latest version.
If using yarn, you can downgrade sass-loader. Use yarn add sass-loader@^10.1.1 it work.
style-loader v3 also dropped support for Webpack 4.
Your package.json
entry should look like this:
"style-loader": "^2.0.0"
I had the same problem here with css-loader v6. Downgrading to v5 seems to work:
"css-loader": "^5.1.1"
This solved for me, for similar problem with Sass:
add to package.json in devDependencies: "sass-loader": "7.3.1", npm i -D sass or yarn add sass --dev remove node_modules npm install or yarn depending on your package manager
My configuration:
"devDependencies": {
"@vue/cli-plugin-babel": "~4.5.0",
"@vue/cli-plugin-eslint": "~4.5.0",
"@vue/cli-service": "~4.5.0",
"babel-eslint": "^10.1.0",
"eslint": "^6.7.2",
"eslint-plugin-vue": "^6.2.2",
"sass": "^1.32.6",
"sass-loader": "7.3.1",
"vue-template-compiler": "^2.6.11"
},
npm install && yarn install
with simply yarn
Ran yarn remove sass-loader
And then installed specifically version 10 as yarn add sass-loader@10
. This totally solved the issue in "vue": "~2.6.12",
In my case I was struggling to compile node-sass on a Centos7 and I solved removing node-sass and putting sass instead.
npm uninstall node-sass
npm install sass
npm install sass-loader^8
The command yarn add sass-loader
installs version 11, which happens not to be compatible with Webpack version 4 and below. The current Vue CLI V4 uses Webpack v4.
You will have to wait until Vue CLI V5 (will use Webpack 5) is released (currently in Beta) in order to use sass-loader v12. Alternatively, you can update to Webpack 5, but be sure to read the CHANGELOG.
NPM downloads dependency packages to modules inside the module if they are in different version then one in your package.json but sometimes it downloads latest version od dependant package (dunno why) into a module..
for example you can have sass-loader: 2.X
in your package.json, and a module XXXX wich also has sass-loader: *
in its dependency packages (you cn check that in package.json inside that XXXX module) npm will download sass-loader 2.X
for you, and sass-loader: 3.X
for the XXXX package - youl get an error.
Quick fix is to remove that additional package from XXXX/node_modules
You can also check what package version the XXXX
module use and try to use the same version in your project.
In my case font-awesome-sass-loader@2.0.1 with project.json:
"dependencies": {
"css-loader": "*",
"sass-loader": "*",
"style-loader": "*"
},
downloaded sass-loader: 3.0.0
while npm downloaded sass-loader: 2.0.0 according to project.json in my project:
"style-loader": "2.0.0"
I removed node_modules/font-awesome-sass-loader/node_modules/
and it fixed the problem.
Issue with different versions, below combination worked:
File: package.json
{
"devDependencies": {
"webpack": "^4.46.0",
"css-loader": "^5.1.1",
"babel-loader": "8.1.0",
"file-loader": "^6.1.0",
"json-loader": "^0.5.7",
"postcss-loader": "^6.2.1",
"raw-loader": "^4.0.1",
"sass-loader": "^12.6.0",
"source-map-loader": "^3.0.1",
"style-loader": "^3.3.1",
"svg-url-loader": "^6.0.0",
"ts-loader": "^5.3.3",
"url-loader": "^4.1.1"
}
}
File: webpack.config.js
module.exports = {
module: {
rules: [
{
test: /\.css$/,
loader: "css-loader",
}
]
}
}
Thanks for @itacode, we just need to do:
that -D
means only dev environment, U can remove it for all environment
yarn:
# yarn add @vue/cli@^4
yarn add -D sass
yarn add -D less
yarn add -D sass-loader@^10
yarn add -D less-loader@^7
or npm:
# npm i @vue/cli@^4
npm i -D sass
npm i -D less
npm i -D sass-loader@^10
npm i -D less-loader@^7
Same here. Downgrading to the following versions helped: "sass": "^1.38.0", "sass-loader": "^10.2.0",
When using Webpack version 4, the default in Vue CLI 4. You need to make sure your loaders are compatible with it. Otherwise you will get errors about conflicting peer dependencies. In this case you can use an older version of the loader that is still compatible with Webpack 4.
# Sass
npm install -D sass-loader@^10 sass
Still not working?
Delete folder node_modules
npm install
