V8安装：

需要一个静态库。解决方法如下：
在R命令行中输入

 Sys.setenv(DOWNLOAD_STATIC_LIBV8 = 1)
install.packages("V8")

fs安装

最近使用R包“DiffBind”分析数据，在安装依赖包“fs”时一直报错，命令行如下：

conda activate chipseq1 
R
library(BiocManager)
BiocManager::install("fs")

错误及解决方法如下：

主要是编译错误，缺少libuv库，或者libuv库编译错误，我下载了libuv，然后按照流程编译

git clone [https://github.com/libuv/libuv.git](https://github.com/libuv/libuv.git) 
cd libuv/
 ./autogen.sh 
./configure --prefix=/your/path/  ##这里不指定路径后边编译会出错，至少我是这样
make
make install
####编译完成后，将lib路径加入环境变量
#方法一： 
export  LD_LIBRARY_PATH=LD_LIBRARY_PATH:/XXX   #但是退出当前终端后就失效

#方法二：
 修改~/.bashrc或~/.bash_profile或系统级别的/etc/profile
