Warnings Occurred While Importing

This warning category contains multiple warnings:

• Failed To Import Module
• Component Was Not Found
• Import Qualifier Must Start With A Capital Letter
• Unknown Import Syntax

Failed To Import Module

What happened?

The module imported via import statement was not found.

This can be caused, for example, by

• a typo in the import statement, or
• a user-defined module that was not built, or
• a wrong import path, or
• a missing module

Why is this bad?

The application can't run because it can't find a module it relies on.

Examples

Typo In The Import Statement

 import QtQuicky // not ok: typo in module name

 Item {
 }

You can fix this warning by correcting the typo:

 import QtQuick // ok: no typo in module name

 Item {
 }

User-Defined Module That Was Not Built

Some tooling like QML Language Server or qmllint can't find user-defined modules when they are not built. If your project defines the QML Module you are trying to import, then the QML tooling will not find it until you build it.

Wrong Import Path

Please refer to the QML import path documentation and to the debugging module import documentation for more information about import paths.

Missing Module

If the previous sections did not help to find the imported module, it might be missing. This might be caused by a missing dependency. When using external libraries, verify that they are actually installed, and that their modules end up in an import path.

Component Was Not Found

What happened?

Some component was not found.

Why is this bad?

The application can't run because it can't instantiate the non-found component.

Examples

Typo In The Component Name

 import QtQuick

 Item {
     Itemy {} // not ok: typo in name
 }

You can fix this warning by correcting the typo:

 import QtQuick

 Item {
     Item {} // ok: no typo in name
 }

Missing Import Statement

 Item { // not ok: must be imported from QtQuick first
 }

You can fix this warning by adding the missing module import:

 import QtQuick

 Item { // ok: was imported from QtQuick
 }

Import Qualifier must start with a capital letter

What happened?

Some imported module has an invalid qualifier.

Why is this bad?

The module imported with this invalid qualifier can't be used.

Examples

 import QtQuick as qq

 qq.Item {
 }

You can fix this warning by making the import qualifier start with an upper case letter:

 import QtQuick as Qq

 Qq.Item {
 }

Unknown Import Syntax

What happened?

An import statement is using an invalid import syntax.

Why is this bad?

The application can't run because it can't import a module it relies on.

Examples

 import "¯\(ツ)/¯:/path/to/Module"
 import QtQuick

 Item {
 }

You can fix this warning by using URLs that have an allowed scheme:

 import "qrc:/path/to/Module"
 import QtQuick

 Item {
 }
