This error message gets thrown at https://github.com/xaverh/vscode-clang-format-provider/blob/master/src/extension.ts#L187. It ususally appears when the clang-format extension cannot find clang-format. It requires clang-format by LLVM in order to work. You can either download it from http://llvm.org or install it via npm install -g clang-format or through a package manager (apt, pacman, brew, nuget, dnf).
