Module Not Found

The compiler cannot find the requested standard library module or local source file.

Why this error occurs

Typo in the imported module name, missing relative path, importing a non-existent file, or omitting file extension in local imports.

Incorrect Code

// incorrect: misspelled standard library or non-existent local file
import std.matth
import "./components/missing_file.nv"

Corrected Code

// corrected: correct standard library path or existing local module
import std.math
import "./components/utils.nv"

print(math.sqrt(16.0))

1Verify standard module names (e.g. std.io, std.fs, std.math, std.net, std.json, std.time).
2Ensure local imported files exist relative to the importing file's directory.
3If the module is a third-party package, check if it is declared in nextviper.toml and run 'nextviper install'.

$ nextviper check$ nextviper install$ nextviper list
