`库中的错误检查点：运行 R 脚本时没有名为“检查点”的包

如何解决`库中的错误检查点：运行 R 脚本时没有名为“检查点”的包

我的系统是 debian 10，测试脚本如下：

me@pc:~$ cat << EOF >> packages.r
#!/usr/bin/Rscript
install.packages('checkpoint',quiet=TRUE,lib='/home/me/R/x86_64-pc-linux-gnu-library/3.5')
library(checkpoint)
checkpoint::setSnapshot("2020-08-26")
EOF

me@pc:~$ ./packages.r
./packages.r
also installing the dependencies ‘curl’,‘pkgcache’,‘pkgdepends’

Warning messages:
1: In install.packages("checkpoint",quiet = TRUE,lib = "/home/me/R/x86_64-pc-linux-gnu-library/3.5") :
  installation of package ‘curl’ had non-zero exit status
2: In install.packages("checkpoint",lib = "/home/me/R/x86_64-pc-linux-gnu-library/3.5") :
  installation of package ‘pkgcache’ had non-zero exit status
3: In install.packages("checkpoint",lib = "/home/me/R/x86_64-pc-linux-gnu-library/3.5") :
  installation of package ‘pkgdepends’ had non-zero exit status
4: In install.packages("checkpoint",lib = "/home/me/R/x86_64-pc-linux-gnu-library/3.5") :
  installation of package ‘checkpoint’ had non-zero exit status
Error in library(checkpoint) : there is no package called ‘checkpoint’
Execution halted

由于包checkpoint无法正确安装，我尝试直接在R shell中安装：

me@pc:~$ R

安装包 checkpoint 时有什么问题？

解决方法

先

apt install libcurl4-openssl-dev，然后这个问题就解决了。
