无法安装shinytest

Question

我在笔记本电脑上安装shinytest时遇到了一些问题。出现以下错误消息。有人能帮我吗？

> install.packages("shinytest")
Installing package into ‘E:/Users/AAAA/BBB/R/win-library/3.6’
(as ‘lib’ is unspecified)
also installing the dependencies ‘ps’, ‘desc’, ‘pkgbuild’, ‘png’, ‘rematch2’, ‘processx’, ‘curl’, ‘pkgload’, ‘praise’, ‘showimage’, ‘debugme’, ‘parsedate’, ‘pingr’, ‘callr’, ‘httr’, ‘testthat’, ‘webdriver’, ‘rstudioapi’


  There are binary versions available but the source versions are later:
      binary source needs_compilation
ps     1.3.0  1.3.2              TRUE
callr  3.4.1  3.4.2             FALSE

Answer 1

看起来有些依赖项('ps'，'callr')可能已过期。在安装“shinytest”之前尝试运行update.packages()。

或者，您可以尝试逐个安装列出的所有依赖项('ps'，'desc'，'pkgbuild'，'png'，...)
