[NodeJS] How the solve problem with building of node-saas(7.0.1) on nodejs 17

Hello, because in some projects I have legacy dependencies (locked versions), I got some problems with modern versions of Node.js interpreter, you will just get errors on trying to build.

You can reproduce it on macOS 12.3.1 and Node.js 17/18. One of the issues – python2, it has issues on modern versions of mac, so you can't install it using brew command.

So, algorithm for solving it:

  1. Install python2 from official site (
  2. which python2
  3. npm config set python /Library/Frameworks/Python.framework/Versions/2.7/bin/python2
  4. Install GCC/clang C++ compiler (hint: you can install Xcode)
  5. CXXFLAGS="--std=c++17" npm i
