带有 .babelrc 的 Babel 如何修复 MODULE_NOT_FOUND？

Question

Babel is telling me a plugin does not exist when it does. (I can compile fine with babel-cli, but that does not support setting pragma options. So I am left to use disgusting .babelrc file) What am I doing wrong here ?

.babelrc

{
    "plugins": [
        "babel-plugin-redom-jsx",
        ["@babel/plugin-transform-react-jsx", {
            "pragma": "el"
        }]
    ]
}

npx babel frontend.js

{ Error: Cannot find module 'babel-plugin-redom-jsx' from '/home/user/Documents/my_program'

package.json :

{
  "devDependencies":
   {
    "@babel/cli": "^7.2.3",
    "@babel/core": "^7.2.2",
    "@babel/plugin-transform-react-jsx": "^7.3.0",
    "@babel/preset-env": "^7.3.0",

    "terser": "^3.14.1"
   }
}

It looks like there is a typo in the docs, as you can check your node_modules folder and you should see babel-plugin-transform-redom-jsx . So your .rc should look like:

{
  "plugins": [
    "babel-plugin-transform-redom-jsx",
    ["@babel/plugin-transform-react-jsx", {
      "pragma": "el"
    }]
  ]
}
