[vite] Internal server error: Failed to resolve import "x" from "src/App.jsx". Does the file exist?
Vite couldn’t find an imported file or package.
[vite] hmr invalidate … Could not Fast Refresh. Export is incompatible.
Fast Refresh fell back to a full reload because the file exports non-components alongside components.
Vue: [Vue warn]: Extraneous non-props attributes (class) were passed to component but could not be automatically inherited because component renders fragment or text root nodes
Attributes (class, style, listeners) passed to a component can't be applied because the component has multiple root nodes.
Vue: [Vue warn]: Set operation on key "name" failed: target is readonly.
You mutated a readonly reactive object (props, `readonly()`, `shallowReadonly`, or a frozen/store state).
Vue: [Vue warn]: Component is missing template or render function.
A component object has neither `template` nor `render`, or an SFC import resolved wrongly.
Vue: [plugin:vite:vue] v-else/v-else-if has no adjacent v-if or v-else-if.
A `v-else` element isn't directly after a `v-if`/`v-else-if` sibling.
Vue: [Vue warn]: Failed to locate Teleport target with selector "#modal". Note the target element must exist before the component is mounted
`` can't find its target element when mounting.
Vue: [Vue warn]: Component provided template option but runtime compilation is not supported in this build of Vue. Configure your bundler to alias "vue" to "vue/dist/vue.esm-bundler.js"
A component uses a string `template` but the runtime-only Vue build has no compiler.
Vue: [vue/no-use-v-if-with-v-for] / Vue 3: v-if has higher priority than v-for — property accessed during render is undefined
Using `v-if` and `v-for` on one element: in Vue 3, `v-if` runs first and can't see the loop variable.
Vue: [Vue warn]: Template compilation error: Tags with side effect (<script> and <style>) are ignored in client component templates
A component template contains ``/`` tags, which Vue won't render.
Vue: [Vue warn]: Invalid prop: type check failed for prop "count". Expected Number with value 5, got String with value "5"
A prop received a value of the wrong type.
Vue: [Vue warn]: Duplicate keys found during update: "5", possible duplicate or missing keys
Items in a `v-for` list share the same `:key`, which breaks Vue's diffing.

Error: Cannot find module 'x' (MODULE_NOT_FOUND)
Node can’t resolve the module path — the package isn’t installed, or a relative path/extension is wrong.
Warning: A component is changing an uncontrolled input to be controlled
An input’s `value` started as `undefined` (uncontrolled) and later became a defined value (controlled), or vice versa.
TS2307: Cannot find module 'x' or its corresponding type declarations.
TypeScript can’t resolve the import — the package isn’t installed, the path alias isn’t configured, or there are no types.
Adjacent JSX elements must be wrapped in an enclosing tag. Did you want a JSX fragment <>...</>?
A component returns two sibling JSX elements without a single parent.
Warning: Cannot update a component (`Parent`) while rendering a different component (`Child`)
A child component updated a parent’s state during its render instead of in an effect or event handler.
Error: createRoot(...): Target container is not a DOM element.
The element passed to createRoot/render doesn’t exist when the script runs.
Vue: [Vue warn]: Avoid mutating a prop directly since the value will be overwritten whenever the parent component re-renders
A child component assigned to a prop. Props flow one way — the parent owns the value.
Vue: [Vue warn]: Missing required prop: "title"
A component marked a prop as `required` but the parent didn't pass it.
Vue: [Vue warn]: Component emitted event "update" but it is neither declared in the emits option nor as an "onUpdate" prop
A component calls `emit("update")` without declaring it in `emits`.
Warning: Received `true` for a non-boolean attribute `x`.
A boolean was passed to a DOM attribute that expects a string, or a custom prop leaked through to a DOM element.
Warning: `key` is not a prop. Trying to access it will result in `undefined` being returned.
A component tried to read props.key, which React reserves and never passes down.
Next.js: Error: Failed prop type: The prop `href` expects a `string` or `object` in `<Link>`, but got `undefined` instead
`` received `undefined` (or another invalid value), so Next.js can't build the link.
npm ERR! code ELIFECYCLE / Command failed with exit code 1
An npm script (build, start, test, postinstall) exited with an error. ELIFECYCLE is only the wrapper — the real error is printed…
gyp ERR! build error / node-gyp rebuild failed
A dependency with native C/C++ code couldn’t compile — missing build tools, Python, or an unsupported Node version.
Error: error:0308010C:digital envelope routines::unsupported
An old build tool (webpack 4, old react-scripts) uses a hash algorithm that OpenSSL 3 in Node 17+ disables.
Vue: [Vue warn]: Property "x" was accessed during render but is not defined on instance
The template references a variable/function that the component doesn’t expose.
Vue: [plugin:vite:vue] Element is missing end tag. / Invalid end tag.
The template has unbalanced HTML tags.
Vue: [plugin:vite:vue] Duplicate attribute. / [vue/no-duplicate-attributes] Duplicate attribute 'class'
The same attribute appears twice on an element in a template.
TypeError: Cannot read properties of null (reading 'addEventListener')
document.querySelector/getElementById returned null, so the element doesn’t exist when the script runs.
DOMException: Failed to execute 'querySelector' on 'Document': 'x' is not a valid selector
The CSS selector string is invalid — often an ID starting with a digit or containing special characters.
ResizeObserver loop completed with undelivered notifications.
A ResizeObserver callback changed layout in a way that triggered another resize in the same frame.
Error: @prisma/client did not initialize yet. Please run "prisma generate"
The generated Prisma Client is missing or out of date.
Error: Node Sass does not yet support your current environment
node-sass (deprecated) has no binary for your Node version/OS.
Error occurred prerendering page "/x". Read more: https://nextjs.org/docs/messages/prerender-error
A page threw an error while Next.js was rendering it at build time.
Vue: [@vue/compiler-sfc] v-model cannot be used on a prop, because local prop bindings are not writable
A template uses `v-model` on a prop (or a `v-for` alias), which can't be assigned.
Webpack: Error: [vue-loader] vue-loader was used without the corresponding plugin. Make sure to include VueLoaderPlugin in your webpack config.
Webpack config uses `vue-loader` but doesn't add its plugin.
ESLint: Parsing error: Unexpected token < / Parsing error: '>' expected (vue-eslint-parser not configured)
ESLint can't parse `.vue` files because the Vue parser isn't configured.
npm ERR! Missing script: "start"
The script name you ran isn’t defined in package.json "scripts".
sh: vite: command not found (npm script)
A tool used in an npm script isn’t installed in node_modules/.bin.
TypeScript: error TS2741: Property 'email' is missing in type '{ name: string; }' but required in type 'User'.
An object lacks one required property of the target type.
TypeScript: error TS7031: Binding element 'name' implicitly has an 'any' type.
A destructured parameter has no type, so its elements default to `any`.
Vue: [Vue warn]: injection "theme" not found.
`inject("theme")` ran but no ancestor provided it.
Angular: NG0955: The provided track expression resulted in duplicated keys for a given collection (@for)
In an `@for` block (or `trackBy`), two items produced the same tracking key, so Angular cannot match them to DOM nodes reliably.
Vue: [Vue warn]: <TransitionGroup> children must be keyed: <li>
Children of `` lack a unique `key`, so animations can't track items.
