Executing webpack failed with exit code 1.

I tried to uninstall node and NativeScript and install them again, but still getting the same error.
I tried to create new project and run it using sidekick but still getting the same error

Webpack seem not to be creating webpack.config.js at all, I can see the plugin is being installed but it doesn't create a webpack.config.js file.

@thecicada what is the version of your nativescript-dev-webpack?

Try running the following:

npm i nativescript-dev-webpack@latest --save-dev
 ./node_modules/.bin/update-ns-webpack --deps --configs
npm i

[thecicada]

@NickIliev Thank you for your response. The version of nativescript-dev-webpack is 1.3.0

I ran

npm i nativescript-dev-webpack@latest --save-dev
 ./node_modules/.bin/update-ns-webpack --deps --configs
npm i

And it worked just fine, thank you. I wonder why this happens for newly created projects. So whenever I create new project in the future, I have to run that commend

The above-mentioned update commands are executed during the postinstall scripts of the nativescript-dev-webpack plugin.

A possible reason for not getting the webpack.config.js could be disabled npm scripts. You could check their status by executing npm config get ignore-scripts. If your scripts are not disabled, I suggest you remove your node_modules and execute npm i --loglevel verbose in order to check the logs of the nativescript-dev-webpack' post-install.
