下面的堆栈跟踪链接帮助我解决了这个问题。

Module build failed: Error: Node Sass does not yet support your current environment: Windows 64-bit with Unsupported runtime (64)
For more information on which environments are supported please see:
https://github.com/sass/node-sass/releases/tag/v4.7.2

这个链接(https://github.com/sass/node-sass/releases/tag/v4.7.2)清楚地显示了所支持的节点版本。

    OS      Architecture    Node
    Windows x86 & x64       0.10, 0.12, 1, 2, 3, 4, 5, 6, 7, 8, 9
    ...     ...             ...    

将节点版本降级到8.11.1后,再次执行npm install。收到以下信息。

Node Sass could not find a binding for your current environment: Windows 64-bit with Node.js 8.x

Found bindings for the following environments:
  - Windows 64-bit with Unsupported runtime (64)

This usually happens because your environment has changed since running `npm install`.
Run `npm rebuild node-sass --force` to build the binding for your current environment.

最后,按照指示运行npm rebuild node-sass——force,一切都开始工作了

其他回答

下面的代码适合我。

npm uninstall node-sass --legacy-peer-deps
npm install node-sass --legacy-peer-deps

我尝试了这个,但它不适合我,并抛出错误:

npm --depth 9999 update 
npm rebuild node-sass

我已经安装了最新的Node.js(目前是11.11.0 Current),在遇到这个问题后,我只是做了以下工作:

降级到推荐版本(目前是10.15.3 LTS) 你可以从NodeJS中获取, 删除node_modules和 然后重新安装纱线:

     yarn install
     yarn start

在执行这些命令之后,一切都运行正常。

对于visual studio 2019,需要更改MSBuild路径

npm config set msvs_version 2017

npm config set msbuild_path "C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\MSBuild\Current\Bin\MSBuild.exe"

npm rebuild node-sass

试试这个:

npm --depth 9999 update
npm rebuild node-sass

答案从2022年开始。我的项目使用node-sass 4.14.1版本。不得不使用以下命令将我的节点降级到12.16.1版本:

npm install node@12.16.1

这解决了这个问题,并允许我再次使用webpack。
