C++ 如何安装opencv4nodejs模块

嗨，我正试图在Node.js项目中使用opencv，所以我决定使用

opencv4nodejs

。我试图通过

npm

安装此模块，发现了一些与计算机上缺少

cmake

相关的错误。因此，我决定通过

brew

安装

cmake

。但在此过程之后，当我尝试安装此模块时，会出现以下错误：

  CMake fails to determine the bitness of the target platform.

    Please check your CMake and compiler installation. If you are cross-compiling then ensure that your CMake toolchain file correctly sets the compiler details.
