aqtinstall 2.1.0

Another unofficial Qt installer

• Release:
• Documentation:
• Test status: and Coverage:

This is a utility alternative to the official graphical Qt installer, for using in CI environment where an interactive UI is not usable, or just on command line.

It can automatically download prebuilt Qt binaries, documents and sources for target specified, when the versions are on Qt download mirror sites.

Note

Because it is an installer utility, it can download from Qt distribution site and its mirror. The site is operated by The Qt Company who may remove versions you may want to use that become end of support. Please don’t blame us.

Warning

This is NOT franchised with The Qt Company and The Qt Project. Please don’t ask them about aqtinstall.

Documentation

There is precise documentation with many examples. You are recommended to read the Getting started section.

• Getting started: https://aqtinstall.readthedocs.io/en/latest/getting_started.html
• Stable (v2.0.x): https://aqtinstall.readthedocs.io/en/stable
• Latest: https://aqtinstall.readthedocs.io/en/latest
• Old (v1.2.5) : https://aqtinstall.readthedocs.io/en/v1.2.5/index.html

Install

Same as usual, it can be installed with pip:

pip install -U pip
pip install aqtinstall

You are recommended to update pip before installing aqtinstall.

Note

aqtinstall depends several packages, that is required to download files from internet, and extract 7zip archives, some of which are precompiled in several platforms. Older pip does not handle it expectedly(see #230).

Note

When you want to use it on MSYS2/Mingw64 environment, you need to set environmental variable export SETUPTOOLS_USE_DISTUTILS=stdlib, because of setuptools package on mingw wrongly raise error VC6.0 is not supported

Warning

There is an unrelated package aqt in pypi. Please don’t confuse with it.

It may be difficult to set up some Windows systems with the correct version of Python and all of aqt’s dependencies. To get around this problem, aqtinstall offers aqt.exe, a Windows executable that contains Python and all required dependencies. You may access aqt.exe from the Releases section, under “assets”, or via the persistent link to the continuous build of aqt.exe.

Example

When installing Qt SDK 6.2.0 for Windows.

Check the options that can be used with the list-qt subcommand, and query available architectures:

aqt list-qt windows desktop --arch 6.2.0

Then you may get candidates: win64_mingw81 win64_msvc2019_64 win64_msvc2019_arm64. You can also query the available modules:

aqt list-qt windows desktop --modules 6.2.0

When you decide to install Qt SDK version 6.2.0 for mingw v8.1:

aqt install-qt windows desktop 6.2.0 win64_mingw81 -m all

The optional -m all argument installs all the modules available for Qt 6.2.0; you can leave it off if you don’t want those modules.

To install Qt 6.2.0 with the modules ‘qtcharts’ and ‘qtnetworking’, you can use this command (note that the module names are lowercase):

aqt install-qt windows desktop 6.2.0 win64_mingw81 -m qtcharts qtnetworking

When aqtinstall downloads and installs packages, it updates package configurations such as prefix directory in bin/qt.conf, and bin/qconfig.pri to make it working well with installed directory.

Note

It is your own task to set some environment variables to fit your platform, such as PATH, QT_PLUGIN_PATH, QML_IMPORT_PATH, and QML2_IMPORT_PATH. aqtinstall will never do it for you, in order not to break the installation of multiple versions.
