Shiny: Shiny works on 3838 but not in RStudio IDE (gray screen) [httpuv]

Created on 18 May 2018 · 15Comments · Source: rstudio/shiny

Hello,

I have two servers in ubuntu 16.04 xenial, the first doesn't work, the new one I Install; and the 2nd works. There are nearly identicals.

The symptom is that the Viewer, or external pane, displays the app and turn gray. It doesn't works even with simple App like Old Faithful Geyser Data . But it works well in web server by 3838.

I have not firewall in those 2 computers.

__1) In this one Shiny 1.1.0 doesn't work into RStudio IDE, but works on web server by 3838__

I've tried Shiny 1.0.5: same.
I've tried to install with dependencies: same.
I've tried to manage with lib path: same.

Same : it works on web but not into RStudio IDE.
Other R commands works well in RStudio IDE.

With these options, I don't see anything.

options(  error = function() {.rs.recordTraceback(TRUE)  })
options(shiny.sanitize.errors = FALSE)
options(shiny.trace= TRUE)

By F12 Network I have a websocket error. I have not Nginx nor Apache, like my old server which is running without errors.

philibe on 22 May 2018

I broke and.... repaired the second which was ok : httpuv_1.3.6.2 + Rcpp_0.12.16 + shiny_1.0.5

install.packages(c( 'https://cran.r-project.org/src/contrib/Archive/httpuv/httpuv_1.3.6.2.tar.gz', 'https://cran.r-project.org/src/contrib/Archive/Rcpp/Rcpp_0.12.16.tar.gz', 'https://cran.r-project.org/src/contrib/Archive/shiny/shiny_1.0.5.tar.gz'), lib='~/R/x86_64-pc-linux-gnu-library/3.4',repos=NULL,type='source', dependencies = TRUE )

For Information httpuv_1.3.6.2 + Rcpp_0.12.16 + shiny_1.1.0 doesn't work
Error in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]) : namespace ‘httpuv’ 1.3.6.2 is being loaded, but >= 1.4.3 is required ERROR: lazy loading failed for package ‘shiny’
After that I have to found and fix the problem of the 1st server which was KO.

same thing that #2073 about httpuv ?

philibe on 24 May 2018

Rstudio IDE works now with shiny on my new server with httpuv_1.3.6.2 + Rcpp_0.12.16 + shiny_1.0.5

I will stay a moment at this config if the dependencies of other packages will not force me to upgrade. (shiny 1.1.0 is maybe too young for every configurations: one week ago :) )

philibe on 24 May 2018

RStudio IDE seems to work with httpuv_1.3.6.2 + shiny_1.0.5 (dependencies = TRUE) and Rcpp_0.12.17 (dependencies = FALSE)

Hi Philibe,
I've same problem after upgrading RStudio to last release.
I've downgraded my libraries as you suggested and now the problem is changed: the shiny popup opens correctly but immediatly it closes without logging errors.
This is my sessionInfo:

It seems something similar to this recent bugfix:
https://github.com/rstudio/rstudio/issues/2061

Do you have idea of what causes it?

Thanks in advance!

Diego

@diegoperoni Does your problem sound like #2085? If so, can you comment on that issue? Thanks!

Hello @diegoperoni

I am not specialist on Shiny Config, only empiric.

What It __seems__ for me, this :

OK: httpuv_1.3.6.2 + shiny_1.0.5 (dependencies = TRUE) and Rcpp_0.12.17 (dependencies = FALSE)
OK : httpuv_1.3.6.2 + shiny_1.0.5 + Rcpp_0.12.16 (dependencies = TRUE).
KO : httpuv_1.3.6.2 + shiny_1.0.5 + Rcpp_0.12.17 (dependencies = TRUE).

2nd one (ok) and 3rd one (ko) : in the sameinstall.packages(); 1st one (ok) with no dependencies for Rcpp_0.12.17.

Maybe it's the luck and the cause is something else I don't know.

diegoperoni on 6 Jun 2018

Thank you @philibe and @diegoperoni, we think we've figured it out!

Underlying issue: https://github.com/rstudio/rstudio/issues/2940
Fix in RStudio: https://github.com/rstudio/rstudio/pull/2951
Workaround in httpuv: https://github.com/rstudio/httpuv/pull/153

Either the RStudio fix OR the httpuv workaround should solve the issue (devtools::install_github("rstudio/httpuv#153") if you want to verify).

Good news :) Thanks.

And as I understand these issues, Shiny 1.1.0 is possible now because it requires httpuv >1.4 fixed.

I will try the fix, but I have a little fear to break my config which works. Maybe I will wait a couple of days the test of @diegoperoni because his config doesn't work.

philibe on 9 Jun 2018

It works perfectly!
Thanks to @jcheng5 and @philibe !

Diego

diegoperoni on 9 Jun 2018

ah yes ? :) I will try at the beginning of the week.

philibe on 9 Jun 2018

Yes. It works :)

OK: shiny_1.0.5 + httpuv_1.4.3.9002
OK: shiny_1.1.1 + httpuv_1.4.3.9002

Thank you :)

(with rstudio-server-1.1.419-amd64.deb not changed)

philibe on 11 Jun 2018

Glad it's working!
