mac m1 bigSur上的npm install opencv4nodejs错误

Question

我一直在尝试使用npm install opencv4nodejs命令安装opencv4nodejs包。但不幸的是，下面的代码被抛出了。我做了一些研究，做了一些调整，但所有这些都不起作用。

以下是错误：

Answer 1

好了，这样我就可以让opencv4nodejs的完整安装正常工作了。我需要将node从版本16降级到版本14，并做了一点编译器选项挖掘！

当前设置

macOS Big Sur v11.6.1

自制 3.3.2

opencv 4.5.3_2

节点 v14.18.1

节点安装(带自制软件)

brew安装节点@14

opencv installation (带自制软件)

brew安装opencv

opencv4nodejs installtion (带节点安装程序)

• 在安装之前设置以下编译器标志

-Wno-c++11-narrowing"

• In CXXFLAGS="-std=c++14在设置了上述环境变量的同一终端上运行安装

npm安装opencv4nodejs

Answer 2

试着这样做

$ export OPENCV4NODEJS_DISABLE_AUTOBUILD=1

$ npm i opencv4nodejs

Answer 3

第1步:使用以下命令查找mac上的opencv lib位置

find / -name "OpenCVConfig.cmake"

步骤2:为您提供以下路径

/opt/homebrew/Cellar/opencv/4.5.2_4/lib

第3步:打开zshrc文件

open ~/.zshrc 

第4步:将以下行放入zshrc文件中

export OPENCV_LIB_DIR="/opt/homebrew/Cellar/opencv/4.5.2_4/lib"

步骤5:保存并关闭zshrc文件步骤6:执行以下命令

source ~/.zshrc 

第七步:现在试着做npm i opencv4nodejs

干杯!
