Web3-react Error Module parse failed: Unexpected token You may need an appropriate loader to handle this file type. web3-react/walletconnect

When I try to integrate web2-react/walletconnect-connector with web3-react using web3-react/core. Other wallets like portis, metamask, fortmatic and few other are working properly but when I use wallet-connector or walletlink it is giving the error.
I used this code web3-react github repo.
Getting runtime error.
Provider
import {
Web3ReactProvider,
} from '#web3-react/core';
import { Web3Provider } from '#ethersproject/providers';
function getLibrary(provider: any) {
const library = new Web3Provider(provider);
library.pollingInterval = 12000;
return library;
}
ReactDOM.render(
<Web3ReactProvider getLibrary={getLibrary} >
<Start />
</Web3ReactProvider>,
document.getElementById('root') as HTMLElement
);
Connector code
import { WalletConnectConnector } from '#web3-react/walletconnect-connector';
export const walletconnect = new WalletConnectConnector({
rpc: { 1: 'https://mainnet.infura.io/v3/84842078b09946638c03157f83405213' },
qrcode: true,
});
Here is the Error

Module parse failed: Unexpected token (44:2)

I'm tried for about 3 days but still no luck . Please help me with this.

It was able to work again after downgrading one below version for them.

i'm in vue project, and build/webpack.base.conf.js add
{
test: /\.js$/,
loader: 'babel-loader',
include: [
resolve('src'),
resolve('test'),
resolve('node_modules/webpack-dev-server/client'),
resolve('node_modules/web3-eth-accounts/lib'),
resolve('node_modules/web3-core-helpers/lib'),
resolve('node_modules/web3-eth-contract/lib'),
resolve('node_modules/web3-core-method/lib')
]
},
the error reason is web3.js syntax not support {...options, ...otherOptions}, it is
Object.assing(options, {
a: 'xxx',
b: 'xxx
})

How to resolve jest error when attempting to run test suite?

I am receiving the following error when attempting to run a test suite using jest:
● Test suite failed to run
TypeError: Cannot read property '1' of undefined
at Plugin.manipulateOptions (node_modules/babel-plugin-module-resolver/lib/index.js:88:9)
at run.next (<anonymous>)
at transform.next (<anonymous>)
I have attempted to resolve the issue by removing node_modules and reinstalling to no avail.

window.matchMedia = window.matchMedia || function () {
return {
matches: false,
addListener: function () { },
removeListener: function () { }
}
}
configure({ adapter: new Adapter() })

Issue resolved. Issue was caused by running the tests by using the "jest" command in the terminal which is different from using the npm test script which also only runs the "jest" command. The difference is the former was using a higher version of Jest which I had installed globally and ended up running into issues whereas the latter used the version of jest that corresponds with the version in the package.json.

undefined is not an object (evaluating 'Component.propTypes') - React Native 0.61.5

I have upgraded the existing react native project from react native 0.59.6 to 0.61.5.
react-native upgrade command not working. So I have done the manual upgrade using upgrade helper. Resolved some post issues. Now project build success.
But After rendering into the ios emulator from Xcode, it is giving the following error.
I am not using Component.propTypes anywhere. package.lock.json have some packages with prop-types. I am not sure what it is doing exactly. Otherwise, inside my project, I am not using
prop-types also. Please find my package.lock.json below,

I have found this https://reactjs.org/warnings/dont-call-proptypes.html regarding this issue. But I am not sure how to use it. Because according to this. some third party libraries using propTypes directly. But how to handle it?
There is no help in 0.61 version Github issues. Please suggest some workarounds for this issue.
Thanks for any help.

Unknown option:
/Users/shooshte/PersonalProjects/teaTimer/node_modules/mobx/lib/mobx.js.extras.
Check out http://babeljs.io/docs/usage/options/ for more information
about options.
A common cause of this error is the presence of a configuration
options object without the corresponding preset name. Example:
Invalid: { presets: [{option: value}] } Valid: { presets:
[['presetName', {option: value}]] }
For more detailed information on preset configuration, please see

JEST and ES6 import - root folder based imports does not working

I have a React project based on React Redux Starter Kit.
In Jest tests: when I trying to import something with root-based path like "components/Link" - it does not work. Only relative paths are working.
Putting
{ "jest": { "rootDir": "<rootDir>/src" } }
in file package.json does not work.
Is there another way?

Final working Jest part of file package.json:
"jest": {
"rootDir": "./src/",
"moduleFileExtensions": ["js", "jsx"],
"moduleDirectories": ["node_modules", "bower_components", "src"],
"verbose": true
}

I think that if you don't want to use relative paths, you have to define additional moduleDirectories, like
// package.json
{
"jest": {
"moduleFileExtensions": ["js", "jsx"],
"moduleDirectories": ["node_modules", "bower_components", "src"],
}
}
More about moduleDirectories in jest docs and configuring jest to find files.

Modifying moduleFileExtensions and moduleDirectories did not work for me. This did in jest.config.js:
moduleNameMapper: {
"src/(.*)": "<rootDir>/src/$1",
},
I found the solution here and found I ony needed to change moduleNameMapper.

This jest config can help:
"jest": {
"rootDir": ".",
"roots": ["<rootDir>"],
"modulePaths": ["<rootDir>"],
}

If you are using 'create-react-app' then install these development dependencies:
"babel-cli": "^6.26.0",
"babel-jest": "^22.4.1",
"babel-preset-react-app": "^3.1.1",
And also update the file .babelrc (create this file if it doesn't exist):
{
"presets": [
"#babel/preset-env",
"#babel/preset-react"
]
}
And now both Jest and npm test both work as they should.
