在最新的R更新中更新rtools35后，Install_package找不到Rtools

Question

devtools::install_github(repo)继续安装rtools35.exe

我尝试从‘author /newrepo’安装一个新的作者帐号存储库，并不断收到R wants to install new buildtoools消息。然后安装退出。Rtools35.exe安装已经完成。我目前使用的是R (3.5.0)的旧版本，因为RTools不能用于3.5.1更新

`devtools::install_github(repo)`

我之前在3.5.1中尝试过remotes，打开了静音，关闭了依赖

remotes::install_bitbucket(account/repo,author,quiet=TRUE,dependencies=FALSE)

但是在Rtools错误之后，我不断地得到Rtools。

我应该试试source()吗？

我应该等待新作者存储库的完整压缩吗？

按作者提供的源代码可在bitbucket上的~src/master中找到

以下代码用于确保可以识别rtools35.exe。请注意，您必须安装pkgbuild才能在devtools加载后安装工具，加载pkgbuild，然后find_tools()解析为true，从而允许您希望安装的源代码

##    code from https://github.com/r-lib/devtools/issues/1772#issuecomment-384406969          ##

install.packages("pkgbuild","G:/Program Files/R/R-3.5.1/library") # pkgbuild is not available (for R version 3.5.0)
install.packages("devtools","G:/Program Files/R/R-3.5.1/library") # make sure you have the latest version from CRAN
library(devtools, lib.loc="G:/Program Files/R/R-3.5.1/library") # load package
devtools::install_github("r-lib/pkgbuild") # install updated version of pkgbuild from GitHub
library(pkgbuild, lib.loc = "G:/Program Files/R/R-3.5.1/library") # load package
find_rtools() # should be TRUE, assuming you have Rtools 3.5
