Ts-loader: Module build failed: TypeError: loaderUtils.getOptions is not a function

[psujit]

I am trying to import a TS project in my JS project using ts-loader, but I am getting the following error. What can be the issue in this case?

Module build failed: TypeError: loaderUtils.getOptions is not a function  
at getLoaderOptions (C:\Users\Sujit\Desktop\Projects\MyProj-Webpack\node_modules\ts-loader\dist\index.js:61:36)
at Object.loader (C:\Users\Sujit\Desktop\Projects\MyProj-Webpack\node_modules\ts-loader\dist\index.js:15:19)
webpack: Failed to compile.

I think we'd need a repro to understand this.

I just had this problem too. In my case, it was caused by an older version of the loader-utils package in node_modules. ts-loader depends on this package, and older versions don't have the getOptions function.

You could manually add a more recent version of loader-utils to your project (npm install loader-utils@latest) or try deleting node_modules and running npm/yarn install to rebuild your dependencies.

@creativecoder I tried updating to the latest version, but I am still getting the same error.
@johnnyreilly What exactly do you need? Steps to reproduce the error?

[creativecoder]

@psujit Can you confirm that in your project you have node_modules/loader-utils/lib/getOptions.js and a reference to getOptions in node_modules/loader-utils/lib/index.js?

If runtime is complaining getOptions is not a function, it's probably not (there)...

any progress on this?

Just saw that error. Was because I had an older version of loader-utils installed, so upgraded it and the error went away.

Closing as stale. Please reopen if you'd like to work on this further.

I'm getting "loaderContext.getOptions is not a function" now in ts-loader 9.0.2 with webpack 4.44, typescript 4.2.3, and loader-utils 2.0.0. I just upgraded to hopefully fix a different set of problems, so I have no real working configuration to go back to or compare. I'm wondering if my timing is coincidental with some breaking change.

ts-loader 9 doesn't support webpack 4: https://github.com/TypeStrong/ts-loader/releases/tag/v9.0.0

i am getting same error, now what is the work around?
"webpack": "^5.35.1",node version:12.18.1

If you're still using Webpack 4, or Node <12, try using ts-loader v8.2.0 it looks like it's the last version with Webpack 4 compatibility: https://github.com/TypeStrong/ts-loader/releases/tag/v8.2.0

@marquizzo thanks, as i my latest storybook lib already have webpack 4.46.0, i had to remove webpack of higher version from package.json, and then with webpack 4 ,ts-loader 8.2.0 is compatible version.these changes solved my problem.
