Can't install package - Githubissues

I tried to install the ggnetwork package by two ways. However, both failed. May I ask how to solve the problem?

#first way
install.packages("ggnetwork")
將程式套件安載入 ‘C:/Users/user/Documents/R/win-library/4.1’
(因為 ‘lib’ 沒有被指定)

  有二進位版本的，但原始碼版本是後來的:
          binary source needs_compilation
ggnetwork  0.5.8  0.5.9             FALSE

安裝原始碼套件 ‘ggnetwork’
