Preface

When we usually use npm to install node-sass dependencies, we will download the .node file from github.com. Due to problems with the domestic network environment, this download may take a long time, or even cause a timeout failure.

This is a frustrating problem that students who use sass may encounter.

The solution is to use other sources, or use tools to download, and then specify the installation source locally.

Solution 1: Use Taobao mirror source

Set the variable sass_binary_site to point to the Taobao mirror address. Example:

npm i node-sass --sass_binary_site=https://npm.taobao.org/mirrors/node-sass/

// 也可以设置系统环境变量的方式。示例

// linux、mac 下

SASS_BINARY_SITE=https://npm.taobao.org/mirrors/node-sass/ npm install node-sass

// window 下

set SASS_BINARY_SITE=https://npm.taobao.org/mirrors/node-sass/ && npm install node-sass

Or set the global mirror source:

npm config set sass_binary_site https://npm.taobao.org/mirrors/node-sass/

Later, when it comes to the installation of node-sass, it will be downloaded from the Taobao mirror.

Solution 2: Use cnpm

In addition, using cnpm to install node-sass will download it from the Taobao mirror source by default, which is also a method:

cnpm install node-sass

Solution 3: Download .node locally

Go here and choose to download the .node file according to the version number and system environment:

https://github. com/sass/node-sass/releases

Then when installing, specify the variable sass_binary_path, such as:

npm i node-sass --sass_binary_path=/Users/lzwme/Downloads/darwin-x64-48_binding.node

Reinstallation problem after installation failure

Finally, some students asked, The previous installation failed and the download will not be downloaded again. What should I do? Then uninstall and then install:

npm uninstall node-sass && npm i node-sass --sass_binary_site=https://npm.taobao.org/mirrors/node-sass/
