在R中工作时，无法在Windows操作系统中安装RopenCVLite

我正在尝试安装RopenCVLite，在Windows操作系统中工作。 我在Windows7、64位环境下的RSTUDIO3.5.0中工作

我遵循安装过程教程

首先，我在我的计算机上安装了Cmake

然后我试着在R中运行下面的代码，安装“RopenCVLite”

我得到以下错误

任何建议都将不胜感激。

Avjit，希望这仍然能帮助您安装ROpenCVLite。就在今天，我遇到了类似的错误问题

cmake: not found

使用命令时，我能够找出安装失败的原因：

devtools::install_github("swarm-lab/ROpenCVLite")

这是因为当你安装cmake时，它会在程序文件下创建自己的路径文件夹（在我的机器上）。顺序应该是首先在根文件夹C上安装Rtools，如下所示：

 C:\Rtools

安装后，然后安装CMake，但需要将路径文件夹更改为C:\Rtools，它将在Rtools下创建并安装CMake。这条安装信息就是我如何确定顺序的。脚本正在Rtools文件夹下查看CMake：

+ cmake -G 'Unix Makefiles' -DCMAKE_C_COMPILER=C:/Rtools/mingw_64/bin/gcc.exe -DCMAKE_CXX_COMPILER=C:/Rtools/mingw_64/bin/g++.exe -DCMAKE_RC_COMPILER=C:/Rtools/mingw_64/bin/windres.exe -DCMAKE_MAKE_PROGRAM=C:/Rtools/bin/make.exe -DENABLE_PRECOMPILED_HEADERS=OFF -DBUILD_opencv_world=OFF -DBUILD_opencv_contrib_world=OFF -DBUILD_matlab=OFF -DPYTHON_EXECUTABLE=OFF -DBUILD_opencv_photo=OFF -DBUILD_PROTOBUF=OFF -DBUILD_SHARED_LIBS=ON -DCMAKE_BUILD_TYPE=RELEASE -DCMAKE_INSTALL_PREFIX=../../../opencv/ ../

CMake错误：找不到CMake_根

您应该能够安装ROpenCVLite而不会出现任何问题。希望这有帮助，如果是这样，请打勾
