Line number is not displayed.

[mkt-engr]

Hi !
I'm in trouble. Line number is not displayed.

In gatsby-config.js, I write the following code.

plugins: [
    {
      resolve: `gatsby-transformer-remark`,
      options: {
        plugins: [
          `gatsby-remark-images`,
          {
            resolve: `gatsby-remark-prismjs`,
            options: {
              showLineNumbers: true,
            },
          },
        ],
      },
    },

And in gatsby-blowser.js

require('prismjs/plugins/line-numbers/prism-line-numbers.css')

And in index.md

for(let i=0;i++,i<10){
  if(i%2===1){
  console.log(i);
  }
}

If I write {numberLines: true} in markdown , line number is displayed. However I don't want to write {numberLines: true} over again and again .

Please tell me how to set up showing line number globally .

Best regards.
