使用Rhino R软件包的纱线依赖性问题

Question

我正在尝试新的r软件包 rhino 来自Appsilon团队来构建光泽应用程序。

在Windows10笔记本电脑上运行，我按照此教程。

的输出

Windows 10 x64 build 19042
R version 4.1.0 (2021-05-18)
rhino: 1.0.0
node: v16.15.0
yarn: 1.22.15

）

yarn run v1.22.15
$ sass --no-source-map --style=compressed root/app/styles/main.scss:root/app/static/css/app.min.css
Error reading root\app\styles\main.scss: no such file or directory.
error Command failed with exit code 66.
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.
Error:
! System command 'yarn' exited with status 66.
i If you can't use Node.js and yarn, try using sass: 'r' configuration.
Run `rlang::last_error()` to see where the error occurred.

这是 Rhino :: Diagnostics （ “这是从“ root/app”开始的。我的应用位于我的主目录中： “ C：/users/xxx/documents/workspace/rhino_dummy”

这些路径在呼叫中是否有可能是错误的？

幸运的是，建议的 libsass 解释器的建议替代方案适用于教程中的SASS示例。在Windows10上使用SASS的Node.js可以为将来更复杂的应用程序工作。

编辑1之后，凯特（Kat）的评论

感谢凯特（Kat）的快速反馈。我通过 YARN添加 sass YARN添加SASS 并再次尝试了相同的错误：

> rhino::build_sass()
yarn run v1.22.15
warning ..\..\package.json: No license field
$ sass --no-source-map --style=compressed root/app/styles/main.scss:root/app/static/css/app.min.css
Error reading root\app\styles\main.scss: no such file or directory.
error Command failed with exit code 66.

Error:

i If you can't use Node.js and yarn, try using sass: 'r' configuration.
Run `rlang::last_error()` to see where the error occurred.

警告来自 pckage.json.json 通过调用<创建的文件。代码>纱线在我的R项目文件夹中。它只有最小的内容：

# package.json
{
  "dependencies": {
    "sass": "^1.51.0"
  }
}

出于好奇心，我试图编译JavaScript示例，在文件夹路径上也出现了非常相似的错误：

> rhino::build_js()
yarn run v1.22.15
warning ..\..\package.json: No license field
$ webpack

Answer 1

对于Node.js函数以在Windows 10上工作，您需要启用开发人员模式在您的系统上，如我们的 how-to：在Windows上使用Rhino 文章。这对于在Windows上工作的符号链接是必需的（ .rhino/node/root 文件是指向项目根的符号链接）。

执行此操作后，从项目中删除 .rhino/node 目录，或在项目的根部运行 rhino :::::: add_node（clean = true）。

Answer 2

解决方案

仅在Windows上启用开发人员模式（有关更多信息，请参见Kamil Zyla的帖子）。

错误消息中的文件夹名称“ root”是一个损坏的变量。

文件夹 ... \ workspace \ rhino_dummy \ .rhino \ node \ node \ root 不存在，但是子结构确实退出：

• app \ styles \ styles \ main.scss
• app \ js \ index.js
• ... \ workspace \ rhino_dummy \ .rhino \ .rhino \ node

fix step1

• 我尝试了运气并创建了文件夹“ root” ： c：\ user \ xxx \ documents \ workspace \ rhino_dummy \ .rhino \ .rhino \ node \ node \ root \ root
• codied rhino_dummy \ app \ styles \ styles \ styles \ styles.scss 。
• ​JS \ index.js
• 运行 Rhino :: build_sass（）和 rhino :: build_js（）现在工作了！

Rhino :: build_sass（）

yarn run v1.22.15
warning ..\..\package.json: No license field
$ sass --no-source-map --style=compressed root/app/styles/main.scss:root/app/static/css/app.min.css
Done in 0.45s.

Rhino :: build_js（）

yarn run v1.22.15
warning ..\..\package.json: No license field
$ webpack
asset app.min.js 470 bytes [compared for emit] [minimized] (name: main)
runtime modules 670 bytes 3 modules
./root/app/js/index.js 113 bytes [built] [code generated]
webpack 5.69.0 compiled successfully in 846 ms
Done in 2.58s.

修复了step2

• 将结果复制回“静态”文件夹，在其中shiny可以预期它们/Rhino
• 复制 Rhino_dummy \ .rhino \ node \ root \ root \ app \ static \ css \ app.min.css to rhino_dummy \ app \ app \ static \ static \ css \ css \ css \ app.min.css
• 复制 \ rhino_dummy \ .rhino \ node \ root \ root \ app \ static \ js \ js \ app.min.js to \ code> \ rhino_dummy \ app \ static \ static \ static \ js \ js \ app.min.js
• 通过 shiny :: shinyappdir（“。”）单击
• 教程中的按钮;-)

检查rhino

sass

• 的定义 YARN（“ build-sass”）
• build-sass
  显示硬编码 root/app/styles/main.scss

js

• build_js（）
  calling yarn("build-js")
• definition of
