Resolving the “No Template Named ‘remove_cv_t’ in Namespace ‘std'” Error

Encountering the error message “no template named ‘remove_cv_t’ in namespace ‘std’; did you mean ‘remove_cv’?” can be a common issue for developers working with Node.js and C++ bindings, particularly when using the node-sass package. This issue typically arises during the compilation process when running yarn install in environments such as Ruby on Rails applications. Here’s a comprehensive guide to help you resolve this error efficiently.

Understanding the Problem

The error occurs during the compilation of node-sass, a package that processes Sass/SCSS styles. This package is initially written in C++ and repackaged as a JavaScript library, requiring compilation on your local machine. The error signifies a compatibility issue between node-sass and Node.js version 16, as Node 16 introduces changes that the older versions of node-sass do not support.

To address this issue, the most effective solution is to update node-sass to a version that supports Node 16. As of version 6.0.1, node-sass is compatible with Node 16. Follow these steps to resolve the error:

  • Update node-sass to version 6.x or later in your project.
  • If you’re using a package manager, such as Yarn or npm, ensure your package.json reflects this updated version.
  • Run yarn install or npm install to apply the changes.

This update should resolve the compilation error, allowing your project to be compatible with Node 16.

Alternative Solutions

If updating node-sass is not feasible, consider these alternatives:

  • Downgrade Node.js to a version that node-sass supports, such as Node 14. Tools like nvm (Node Version Manager) can help manage multiple Node versions.
  • Modify your node-gyp configuration to use a different C++ standard, such as C++17, which may bypass the error. Use the command: CXXFLAGS="--std=c++17" yarn install.
