Hi @guijie2015,
I had the same issue and installed the BH package as indicated here https://r-forge.r-project.org/R/?group_id=1469.
However when I try again to install velocyto.R via devtools I get exactly the same error.
Do you know I can make R to find the boost libraries?
you need to install boost libraries in your system, not the packages in your R
Boost库是为C++语言标准库提供扩展的一些C++程序库的总称，其广泛地作为各种第三方库的依赖库，例如PCL，Caffe等。接下来将介绍在Windows环境下如何安装boost库。
首先在Boost官网（https://www.boost.org/）上下载所需的压缩文件，然后解压后打开会发现如下文件
找到tools文件夹里的build文件下的bootstrap.bat文件，打开command命令窗口后运行bootstrap.bat文件将出现如下截图
然后想好你要安装的目录，这里我给的是’D:\Program Files (x86)\boost_1_71_0\build’，因此你会看到如下截图
直接运行即可，系统会出现一大串代码一直跑，跑完即可
Finally，Congratulations! O(∩_∩)O~~
