This document covers some common node-sass issues and how to resolve them. You should always follow these steps before opening a new issue.

- Glossary
- Using node-sass with Visual Studio 2015 Task Runner.
- Installing node-sass 4.x with Node < 4
If you see a 404 when trying to install node-sass, this indicates that your trying to install a version of node-sass that doesn't support your version of NodeJS, or uses an alternate V8 environment (Meteor, Electron, etc...) that isn't supported by node-sass.

If you encounter this, please check what version of NodeJs you're running (node -v
)
and check for a supported version of node-sass for your NodeJs by checking our
release page.
If you work in behind a corporate proxy try setting the proxy variables. The following is a guide for setting this up.
This can happen if you are install node-sass as root
, or globally with sudo
.
This is a security feature of npm
. You should always avoid running npm
as
sudo
because install scripts can be unintentionally malicious.
Please check npm documentation on fixing permissions.
If you must however, you can work around this error by using the --unsafe-perm
flag with npm install i.e.
sudo npm install --unsafe-perm -g node-sass
If this didn't solve your problem please open an issue with the output from our debugging script.
Some users upgrading from previous versions of npm before 5 have found conflicts with old lock file formats. This may be show up as a URL instead of the actual version number when downloading the binary. EX:
Downloading binary from https://github.com/sass/node-sass/releases/download/vhttps://registry.npmjs.org/node-sass/-/node-sass-4.5.3.tgz/win32-x64-57_binding.node
Cannot download "https://github.com/sass/node-sass/releases/download/vhttps://registry.npmjs.org/node-sass/-/node-sass-4.5.3.tgz/win32-x64-57_binding.node":
HTTP error 404 Not Found
The easiest way to get around this is just to cleanup the npm files and reinstall.
rm -rf node_modules
rm package-lock.json
npm cache clean
npm install
To determine which version of Node.js or io.js you are currently using run the following command in a terminal.
node -v
The resulting value the version you are running.
Node sass runs some install scripts to make it as easy to use as possible, but some times there can be issues. Before opening a new issue please follow the instructions for Windows or Linux/OSX and provide their output in you GitHub issue.
Remember to always search before opening a new issue.
Firstly create a clean work space.
mkdir \temp1
cd \temp1
Check your COMSPEC
environment variable.
node -p process.env.comspec
Please make sure the variable points to C:\WINDOWS\System32\cmd.exe
Gather some basic diagnostic information.
npm -v
node -v
node -p process.versions
node -p process.platform
node -p process.arch
Clean npm cache
npm cache clean
Install the latest node-sass
npm install node-sass@latest
Note which version was installed by running
npm ls node-sass
[email protected] /tmp
└── [email protected]
If node-sass couldn't be installed successfully, please publish your npm.log
and npm.err
files for analysis.
You can download reference known-good logfiles to compare your log against.
If node-sass install successfully lets gather some basic installation information.
node -p "require('node-sass').info"
node-sass 3.8.0 (Wrapper) [JavaScript]
libsass 3.3.6 (Sass Compiler) [C/C++]
If the node-sass installation process produced an error, open the vendor folder.
cd node_modules\node-sass\vendor
Then, using the version number we gather at the beginning, go to https://github.com/sass/node-sass/releases/tag/v<your-version>
.
There you should see a folder with same name as the one in the vendor
folder.
Download the binding.node
file from that folder and replace your own with it.
Test if that worked by gathering some basic installation information.
node -p "require('node-sass').info"
node-sass 3.8.0 (Wrapper) [JavaScript]
libsass 3.3.6 (Sass Compiler) [C/C++]
If this still produces an error please open an issue with the output from these steps.
Firstly create a clean work space.
mkdir ~/temp1
cd ~/temp1
Gather some basic diagnostic information.
npm -v
node -v
node -p process.versions
node -p process.platform
node -p process.arch
Install the latest node-sass
npm install node-sass@latest
Note which version was installed by running
npm ls node-sass

If you are using node-sass with VS2015 Task Runner Explorer, you need to make
sure that the version of node.js is same as the one you installed node-sass
with. This is because for each node.js runtime modules version (node -p process.versions.modules
)
, we have a separate build of native binary. See #532.
Alternatively, if you prefer using system-installed node.js (supposedly higher version than one bundles with VS2015), you may want to point Visual Studio 2015 to use it for task runner jobs by following the guidelines.
See the discussion in this comment for a workaround. As of node-sass@v5 only Node 6 and above will be officially supported.
