我有一个在本地工作正常的应用程序，我想将它部署到shinyapps.io。我创建了一个目录（dataviz），应用程序代码位于名为app.R的文件中。从RStudio运行deployApp（＆＃34; dataviz＆＃34;）时，它开始部署但到达失败的地方并出现错误：
** preparing package for lazy loading
Error in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]) :
there is no package called ‘htmltools’
ERROR: lazy loading failed for package ‘rcdimple’
* removing ‘/usr/local/lib/R/site-library/rcdimple’
################################### End Log ###################################
Error: Unhandled Exception: Child Task 27328802 failed: Error building image: Error building rcdimple (0.1). Build exited with non-zero status: 1
不确定这里会发生什么，非常感谢任何帮助。
app.R就是这样

@timelyportfolio - 似乎htmltools的依赖关系未列在rcdimple包的DESCRIPTION文件中。从https://github.com/timelyportfolio/rcdimple分叉包，并将依赖项添加到DESCRIPTION文件（https://github.com/kilimba/rcdimple）。现在可以部署使用rcdimple包到shinayapps.io的闪亮应用。已经提出拉动请求以掌握分支
