Missing gray-matter dependency in @vuepress/shared-utils #1190
Description
- I confirm that this is a issue rather than a question.
Bug report
I am using the @vuepress/markdown-loader package in another project.
This package requires @vuepress/shared-utils.
The parseFrontmatter.ts file requires the gray-matter module which is not present in the package.json of @vuepress/shared-utils.
Version
$ npm list | grep -2 @vuepress/markdown-loader
└─┬ @vuepress/[email protected]
├─┬ @vuepress/[email protected]
│ ├─┬ @vuepress/[email protected]
Steps to reproduce
- Create a package that requires
@vuepress/markdown-loader(e.g.npm install @vuepress/markdown-loader) - Install webpack:
npm install webpack webpack-cli - Add a Markdown file (e.g.
Example.md) - Configure webpack to use the markdown file as entry and the the markdown-loader to compile it:
const path = require('path')
module.exports = {
entry: path.resolve(__dirname, 'Example.md'),
output: {
path: path.resolve(__dirname, 'dist'),
filename: 'file.js'
},
module: {
rules: [
{
test: /\.md$/,
use: [
{
loader: require.resolve('@vuepress/markdown-loader'),
options: {
sourceDir: path.resolve('chapters')
}
}
]
}
]
}
}- Run webpack
What is expected?
The markdown loader compiles all Markdown files.
What is actually happening?
Webpack throws the following warnings:
WARNING in ./Example.md
