[[[ INSTALL ISSUES ]]] 404 node-pre-gyp ERR! Pre-built binaries not found for v8-debug stack Error: Failed to execute
Explanation of the problem
When running the
npm install -g node-inspector command, an error occurs during the installation process. The error message suggests that the tool ‘xcodebuild’ requires Xcode, but the active developer directory ‘/Library/Developer/CommandLineTools’ is a command line tools instance. To resolve this issue, the user attempted to switch the active developer directory to the Xcode installation location using the command
sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer.
xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
After following the instructions, the installation process continues, but another error occurs during the installation of the
v8-debug package. The error message indicates that there are too few arguments provided to function calls in the
debug.cc file. These errors prevent the successful installation of the package, resulting in the overall failure of the
npm install command.
node-pre-gyp ERR! Tried to download(404): https://node-inspector.s3.amazonaws.com/debug/v0.7.7/node-v51-darwin-x64.tar.gz ... ../src/debug.cc:38:27: error: too few arguments to function call, expected at least 2, have 1 v8::Debug::Call(fn); ~~~~~~~~~~~~~~~ ^ ../src/debug.cc:46:61: error: too few arguments to function call, single argument 'isolate' was not specified ... 4 errors generated. make: *** [Release/obj.target/debug/src/debug.o] Error 1
This error suggests that the
v8-debug package is unable to find the pre-built binaries for the specified version of Node.js and falls back to source compilation using
node-gyp. However, there are missing or incorrect arguments in the source code, leading to build errors and ultimately causing the installation to fail.
Please note that resolving this issue may require troubleshooting the specific version compatibility between the
v8-debug package, Node.js version, and the target operating system.

A brief introduction to node-inspector
Node-inspector is a powerful debugging tool for Node.js applications. It provides a web-based interface that allows developers to inspect and debug their Node.js code using the Chrome Developer Tools. With node-inspector, developers can set breakpoints, step through code, examine variables, and monitor the execution flow of their Node.js applications in a familiar and intuitive manner.
The tool works by leveraging the V8 debugging protocol, which is the same protocol used by the Chrome Developer Tools. It attaches to a running Node.js process and establishes a communication channel between the debugger and the application. This enables developers to interactively debug their Node.js code in real-time, gaining insights into the runtime behavior and identifying and resolving issues more efficiently.
Node-inspector provides a user-friendly interface that displays the source code, call stack, and breakpoints, allowing developers to navigate and analyze their code effectively. It also supports various debugging features, such as watch expressions, console logging, and network monitoring. Additionally, node-inspector integrates seamlessly with popular IDEs and text editors, making it a valuable tool for Node.js developers to diagnose and fix bugs, optimize performance, and gain a deeper understanding of their applications’ runtime behavior.
