electron 在Windows 10上使用Opencv4nodejs构建电子应用程序的问题

我已经建立了一个电子应用程序，使用tensorflow和opencv 4 nodejs。
当我使用npm start时，这个应用程序运行得很好。但是，当我试图构建我的应用程序时，它却突然出现了以下错误：

这里的问题是我没有从源代码构建opencv 4 nodejs，而是手动安装了opencv，然后禁用自动构建来为我的应用程序安装它。
从错误中，我看到它正在opencv-build下查找lib目录，但它根本不在那里。
有没有办法不重建任何东西，因为我已经有了所有的模块为Windows 10？
我相信这是一些简单的事情，但已经碰到了一堵砖墙。
这是我的包裹。

因此我意识到在执行npm run build之前需要设置以下环境变量
因为我在构建opencv4nodejs时使用了它们。

Installing OpenCV Manually
Setting up OpenCV on your own will require you to set an environment variable to prevent the auto build script to run:

# linux and osx:
export OPENCV4NODEJS_DISABLE_AUTOBUILD=1
# on windows:
set OPENCV4NODEJS_DISABLE_AUTOBUILD=1
Windows
You can install any of the OpenCV 3 or OpenCV 4 releases manually or via the Chocolatey package manager:

# to install OpenCV 4.1.0
choco install OpenCV -y -version 4.1.0
Note, this will come without contrib modules. To install OpenCV under windows with contrib modules you have to build the library from source or you can use the auto build script.

Before installing opencv4nodejs with an own installation of OpenCV you need to expose the following environment variables:

OPENCV_INCLUDE_DIR pointing to the directory with the subfolder opencv2 containing the header files
OPENCV_LIB_DIR pointing to the lib directory containing the OpenCV .lib files
Also you will need to add the OpenCV binaries to your system path:

add an environment variable OPENCV_BIN_DIR pointing to the binary directory containing the OpenCV .dll files
append ;%OPENCV_BIN_DIR%; to your system path variable
