r - 使用 Photon 的 R 闪亮独立应用程序

问题描述

我正在寻找一种从 Shiny App 创建独立应用程序的简单方法。我第一次看到凯蒂（见谷歌）的“闪亮遇见电子”演讲。浏览他们的网站后，我认为 Photon 是他们最新的方法！

我尝试以最简单的方式测试 Photon，但没有成功。

To test Photon, I did the following:

1. install node.js (works, tested 'npm' in CMD line, recognised)

2. install git (works, tested 'git' in CMD line, recognised)

3. install Photon using your instructions

4. Open new basic shinyApplications: RStudio > File > New file > Shiny Web App... >>
--> Name 'PhotonTestApp'
--> multiple fFIle (ui.R/server.R)
--> C:/ShinyApps
Tested to see the app works, the basic Geyser data app.

5. setwd("C:\ShinyApps\PhotonTestApp\")

6. Launch Photon app builder
--> Shiny App Directory: C:/ShinyApps/temp
--> left default NULL in all three package inputs
--> Build

我收到以下错误：

> photon:::photon_rstudioaddin()
Listening on http://127.0.0.1:3898
[1] "Selected directory: "
[1] "Selected directory: C:/ShinyApps/temp"
Running Photon
Warning in normalizePath(path.expand(path), winslash, mustWork) :
path[1]="C:\ShinyApps\temp/electron-quick-start": The system cannot find the file specified

我看到创建了一个目录：C:\ShinyApps\temp\electron-quick-start\，其中隐藏了一个空的 .git 目录。

一些附加信息：
