Failed to compile. about ethereum-boilerplate

[YosephKS]

Alright fixed guys 🙌🏼 pull the latest version and have a check and let us know~

[Y0moo]

Hey @mrtornado @Ajay67

Please remove your node_modules folder, yarn.lock/package-lock. Fetch new version of the boilerplate and run yarn install

[cvramire]

i have this error when running yarn install
error Couldn't find package "eslint-plugin-import@^2.22.1" required by "[email protected]" on the "npm" registry.

[kuabhish]

solution? facing same issue please

[blockjester]

Seems to be a dependency tree issue, eslint related? Seems there are two versions 8.8.0 and 7.32.0 and they don't get along?

❯ npm ls eslint                                                                                                                      09:11:15 AM

What is the solution?

[kuabhish]

what I did is went to a older commit and it worked.

[CodeXSky]

@kuabhish if you checkout to older commit, it probably missing files config. Anyone else have solution for update eslint to resolve this?

[blockjester]

I do welcome the eslint and prettier.. but spent the better part of today banging my head trying to fix this by checkout out an older commit and re-installing. Still doesn't work for me.

[kuabhish]

I dont know about this config file @CodeXSky
but going to commit cfffb45755287226ab01f560343a5442cd9ec313 worked for me @blockjester

[YosephKS]

Hey @kuabhish @CodeXSky @blockjester @CyrusSaei @cvramire if you are having the latest version of ethereum-boilerplate 🙌

if any of you get this error

 Line 0:  Parsing error: ImportDeclaration should appear when the mode is ES6 and in the module context

then, simply replace the content of your .eslintrc with this

{
  "settings": {
    "react": {
      "version": "detect"
    }
  },
  "env": {
    "browser": true,
    "node": true,
    "es2021": true,
    "jest": true
  },
  "extends": [
    "eslint:recommended",
    "plugin:react/jsx-runtime",
    "plugin:react/recommended",
    "plugin:prettier/recommended",
    "plugin:react-hooks/recommended"
  ],
  "parserOptions": {
    "ecmaFeatures": {
      "jsx": true
    },
    "ecmaVersion": 12,
    "sourceType": "module"
  },
  "plugins": ["react"],
  "rules": {
    "react/react-in-jsx-scope": "off",
    "react/prop-types": "off",
    "react/jsx-key": "off",
    "react/no-unescaped-entities": "off"
  }
}

What I do is:

1. set "ecmaVersion": 12
2. add some new rules to off

I'll try to make a patch PR to fix this next ASAP.

[YosephKS]

Thank you again y'all @kuabhish @CodeXSky @blockjester @CyrusSaei @cvramire for reporting, a patch fix PR is on its way 🙌🏼 appreciate all your inputs

YosephKS

Thanks so much 🙏

[blockjester]

Thank you!

[CodeXSky]

Alright fixed guys 🙌🏼 pull the latest version and have a check and let us know~

Thank you !

1 hour ago I have downloaded, then installed packages and complied using both npm and yarn but got a lot of errors. Below are the last lines of the errors

[mrtornado]

yea I'm getting the same errors :) Somebody messed up the template, yesterday was working just fine :)

@Y0moo It's now working. Thanks for the quick response.

[kushcoin]

This has been a nightmare.. I have never had so many issues with anything labeled "boilerplate"... Cannot get the environment setup even as there is just so much broken or deprecated crap its ridiculous. Tired of even trying.

[Y0moo]

@kushcoin Please provide some details so I will be able to help you

[kushcoin]

It's requesting I polyfill each module because webpack no longer includes them for node.js i will make a list of other issues too, but I cannot find webpack.config.js
