Question

我正在尝试关注Hadley Wickham's guide to create packages，但在完全遵循他的步骤后我遇到了错误。我知道很多其他人都没有错误，所以我不确定如何继续。

到目前为止，这是我的输入和输出：

> install.packages(c("devtools", "roxygen2", "testthat", "knitr"))

到目前为止，一切似乎都很顺利，但在这里打破了。

我应该更改什么才能使用has_devel函数？

Answer 1

尝试通过运行具有管理员权限的RStudio来安装dev_tools。

Answer 2

我有同样的问题。 has_devel（）和find_rtools（）似乎没有出现在我安装的devtools包中。

所以不要像在Hadley的指示中那样从github安装：

devtools::install_github("hadley/devtools")

我使用以下方法从CRAN安装了devtools：

install.packages("devtools")

之后

devtools::find_rtools()

和

devtools::has_devel()

成功运行

为什么我的devtools缺少has_devel（）函数？
