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]: Maximum recursive updates exceeded in component <Foo>. This means you have a reactive effect that is mutating its own dependencies and thus recursively triggering itself
A watcher/computed/render effect keeps changing the state it depends on, creating an infinite update loop.
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: [Vue warn]: Write operation failed: computed value is readonly
You assigned to a `computed` that has no setter.
Vue: [Vue warn]: Unhandled error during execution of mounted hook / TypeError: Cannot read properties of undefined (reading 'x')
An exception was thrown inside a lifecycle hook, watcher, event handler or render, and Vue logs it with the context.
Vue: [Vue warn]: onMounted is called when there is no active component instance to be associated with
A lifecycle hook was registered outside `setup()` (or after an `await`).
Vue 2: [Vue warn]: Avoid adding reactive properties to a Vue instance or its root $data at runtime - declare it upfront in the data option
In Vue 2 you added a property to the root data (or instance) after creation, which can't be made reactive.
Vue: [Vue warn]: Vue received a Component that was made a reactive object — mark it with `markRaw` or use `shallowRef`
A component definition was stored in a `ref`/`reactive`, making Vue proxy it unnecessarily.
Two steps away (17)
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.
Vue: [Vue warn]: Failed to resolve component: x
The template uses a component tag that isn’t registered or imported where it’s used.
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: [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).
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/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.
Vite/Vue: [plugin:vite:import-analysis] Failed to parse source for import analysis — you may need to install appropriate plugins to handle the .vue file format
Vite can't process `.vue` files because the Vue plugin isn't installed/enabled.
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.
Vue: [Vue warn]: injection "theme" not found.
`inject("theme")` ran but no ancestor provided it.
Pinia: Error: [🍍]: "getActivePinia()" was called but there was no active Pinia. Are you trying to use a store before calling "app.use(pinia)"?
A store was used before Pinia was installed or outside a component context (router guards, plain modules).
Nuxt: [nuxt] [useAsyncData] key must be a string / useFetch only works inside setup, plugins or middleware
`useFetch`/`useAsyncData` were used in an event handler, after an await, or without a key where one is required.
Vue 2: [Vue warn]: Error in v-on handler: "TypeError: Cannot read property 'x' of undefined"
An exception was thrown inside a Vue 2 event handler or lifecycle hook, logged with context.
Warning: Function components cannot be given refs. Attempts to access this ref will fail. Did you mean to use React.forwardRef()?
A ref was passed to a function component that doesn’t forward it.
