Question

尝试安装devtools，但不断出现错误

Error : object ‘glue_collapse’ is not exported by 'namespace:glue' ERROR: lazy loading failed for package ‘usethis’

下面是完整的错误代码：

> install.packages('devtools', repos='http://cran.rstudio.com/')
also installing the dependency ‘usethis’


  There are binary versions available but
  the source versions are later:
         binary source needs_compilation
usethis   1.4.0  1.5.0             FALSE
devtools 1.13.6  2.0.2             FALSE

installing the source packages ‘usethis’, ‘devtools’

我已经安装了tidyverse，其中包含glue软件包，但是glue_collapse仍然存在问题。另外，是否可以关闭延迟加载以解决“ usethis”依赖性问题？尝试过搜索方式，但没有成功的方法。

添加我的原始评论作为答案以标记此问题已解决。原来我需要单独安装胶水包，然后解决了使用这个问题。
