我试图部署一个shinyapp，但系统提示我一个错误，这是purrr包，curl和代理问题...我想访问后端终端sudo安装它但不知道beta.rstudioconnect的用户和密码。 com，有人给我一个灯光吗？

Unable to fully restore the R packages associated with this deployment.
06/01 11:25:37.297
Please review the preceding messages to determine which package
06/01 11:25:37.297
encountered installation difficulty and the cause of the failure.
06/01 11:25:37.297
06/01 11:25:37.297
Some typical reasons for package installation failures:
06/01 11:25:37.297
* A system library needed by the R package is not installed.
06/01 11:25:37.297
Some of the most common package dependencies are cataloged at:
06/01 11:25:37.297
https://github.com/rstudio/shinyapps-package-dependencies
06/01 11:25:37.297
06/01 11:25:37.297
* The R package requires a newer version of R.
06/01 11:25:37.297
06/01 11:25:37.297
* The C/C++ compiler is outdated. This is often true for packages
06/01 11:25:37.297
needing C++11 features.
06/01 11:25:37.297
06/01 11:25:37.297
* The R package is Windows-only or otherwise unavailable for this
06/01 11:25:37.297
operating system.
06/01 11:25:37.297
06/01 11:25:37.297
* The package is housed in a private repository that requires
06/01 11:25:37.297
authentication to access. For more details on this, see:
06/01 11:25:37.297
http://docs.rstudio.com/connect/admin/process-management.html#private-packages
06/01 11:25:37.297
06/01 11:25:37.297
The package description and documentation will list system requirements
06/01 11:25:37.297
and restrictions.
06/01 11:25:37.297
06/01 11:25:37.297
Please contact your RStudio Connect administrator for further help
06/01 11:25:37.297
resolving this issue.
