Install from local not working

[BenWiseman]

Finshed: Installing your Shiny package into electricShine framework Error in system.file("extdata", "icon", package = my_package_name, lib.loc = library_path) : 'package' must be of length 1

I could just be not understanding the documentation, but it seems like local install isn't passing through the package path from local_package_path or something.

[BenWiseman]

Here is where it breaks:

`
my_package_name <- electricShine::install_user_app(library_path = library_path ,
repo_location = "local",
repo = local_package_path,
repos = cran_like_url,
package_install_opts = package_install_opts)
}

Transfer icons if present -----------------------------------------------

electron_build_resources <- system.file("extdata",
"icon",
package = my_package_name,
lib.loc = library_path)`

Because electricShine::install_user_app can only return a NULL as it just gives the result of readLines() on a newly created tempfile?

I'm happy to help make this thing a reality, but, the code in install_user_app is really confusing. Like, are all of the environment variables just being used to prevent you from having to pass variables between functions?

I am probably encountering the same issue when executing this on a fresh R 4.0.3 x64 install.

install.packages("remotes")
remotes::install_github("chasemc/electricShine")

buildPath <- paste(getwd(), "build", sep="/")

electricShine::electrify(
    app_name = "My_App",
    short_description = "My demo application",
    semantic_version = "1.0.0",
    build_path = buildPath,
    mran_date = NULL,
    cran_like_url = "https://cran.r-project.org",
    function_name = "run_app",
    git_host = NULL,
    git_repo = NULL,
    local_package_path = getwd(),
    package_install_opts = list(type = "binary"),
    run_build = TRUE
)

in the cloned https://github.com/chasemc/demoApp folder.

Installing the package rlang did not help, as I guessed, because it was mentioned in the log.

I am having the very same issue as described by @BenWiseman

[marecabo]

I solved this issue for me with properly installing rlang from source in my base R installation (outside the renv) environment. RTools was also in my path.

After also specifying a custom nodejs_path as argument (see

electricShine/R/meta_function.R

Line 44 in 6f53a08

nodejs_path = file.path(system.file(package = "electricShine"), "nodejs"),

maybe related: #308), it ran further and I encountered #343 for which a not-yet-merged fix exists.

With that, the demo app starts but loads indefinitely (see #343 (comment) and following) and this error message appears:

A JavaScript Error occurred in the main process

Uncaught exception:
Error: read ECONNRESET
    at TCP.onStreamRead (internal/stream_base_commons.js:200:27)

[Wladimir-Sanyer]

any solution? the problem persists and does not allow the application to be carried out normally

I'm planning to work on the package in the next couple weeks. My assumption is that @marecabo is correct. Using electricShine from renv is likely to cause issues
