【问题描述】：

尝试安装 devtools，但一直报错

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

以下是完整的错误代码：

> 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 包，但仍然遇到glue_collapse 的问题。此外，是否可以关闭延迟加载以修复“usethis”依赖问题？尝试了搜索方法，但没有成功的方法。

【问题讨论】：

已修复！原来我需要单独安装glue 包，然后修复了usethis 问题。
