问题背景
开发新的前端项目时,总少不了搭建开发环境和执行npm install安装依赖包,但npm install的过程总是充满着玄学,很难保证一次性成功,其中尤其以node-sass这个包的安装失败问题最为常见。
像其他npm包安装失败,通常是因为网络问题,可以采用使用更好的网络环境或者切换源的方式进行安装,比如使用淘宝的源进行安装,命令如下:
npm install --registry=https://registry.npm.taobao.org
但node-sass安装失败这个问题似乎无法通过上述命令解决。本文将总结遇到此类问题时的解决方案。
问题描述
笔者的测试环境如下:
操作系统:Windows 11 Node版本:v14.16.0 Npm版本:6.14.11
遇到的node-sass安装失败的报错如下:

解决方案
1. 检查node-sass安装版本是否正确。
本地安装的node版本不同,需要安装的node-sass版本也是不一样的。node-sass官方给出了不同版本的node和node-sass的对应关系,读者可访问node-sass github仓库或者node-sass npm仓库进行查看。
本地安装的node版本,可以使用如下命令进行查看:
node -v
下图为截至node-sass@8.0.0版本时的对应关系。
在项目中还没有package.json或者有package.json但是此文件没有指定node-sass的版本时,默认会安装node-sass的最新版本。由于笔者安装的node版本时14.16.0,执行npm install node-sass命令默认安装了撰写本文时的node-sass最新版本8.0.0,所以才有了前文中报错。
根据版本对应关系,笔者应该安装node-sass的4.14+版本,因此需要将安装命令改为:
npm install node-sass@^4.14.0 --registry=https://registry.npm.taobao.org
这样就是使用淘宝源来安装node-sass的4.14+中的最新版本。
2. 检查是否是网络问题
在使用npm install安装node-sass时,会从 github.com 上下载 .node 文件。由于国内网络环境的问题,这个下载时间可能会很长,甚至导致超时失败。
npm WARN deprecated @npmcli/move-file@2.0.1: This functionality has been moved to @npmcli/fs npm WARN deprecated @npmcli/move-file@1.1.2: This functionality has been moved to @npmcli/fs > node-sass@8.0.0 install D:\temp\npm-temp\node_modules\node-sass > node scripts/install.js Downloading binary from https://github.com/sass/node-sass/releases/download/v8.0.0/win32-x64-83_binding.node Cannot download "https://github.com/sass/node-sass/releases/download/v8.0.0/win32-x64-83_binding.node": HTTP error ETIMEDOUT request to https://github.com/sass/node-sass/releases/download/v8.0.0/win32-x64-83_binding.node failed, reason: connect ETIMEDOUT 20.205.243.166:443 Hint: If github.com is not accessible in your location try setting a proxy via HTTP_PROXY, e.g. export HTTP_PROXY=http://example.com:1234 or configure npm proxy via npm config set proxy http://example.com:8080 > node-sass@8.0.0 postinstall D:\temp\npm-temp\node_modules\node-sass > node scripts/build.js
附上报错截图。
这种情况下仅使用--registry参数指定npm包的下载源是不够的,还需要使用--sass_binary_site参数指定sass二进制文件的下载源,因此需要将安装命令改为:
npm install node-sass@^4.14.0 --registry=https://registry.npm.taobao.org --sass_binary_site=https://npm.taobao.org/mirrors/node-sass/
这样一来就是指定node-sass版本,指定npm包下载源为淘宝源,指定sass下载源为淘宝源,使用此命令基本就都能安装成功了。
总结
遇到node-sass安装失败时,可以使用以下命令:
# 查看本地node版本 node -v # 安装node-sass npm install node-sass@[本地node所对应的node-sass版本] --registry=https://registry.npm.taobao.org --sass_binary_site=https://npm.taobao.org/mirrors/node-sass/
