there is no package called ‘httpuv’

I try to make installer using https://github.com/zarathucorp/FeederNetEstimation

```r
create_app(app_name = "FeederNetEstimation",
app_repo_url = "https://github.com/zarathucorp/FeederNetEstimation",
app_dir = "/myapp"
pkgs = c("ggplot2", "DT", "data.table", "jsmodule", "shinycustomloader", "shinyhttr", "shinyWidgets", "zip", "htmltools", "devEMF")
)
```
After click execute file, I see only white background with **there is no package called ‘httpuv’**

How can I solve the problem?

sincerely
