This article introduces the relevant knowledge of "how to install pyqt5 and its related configuration with pycharm". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

First, configure a special virtual environment

Reason: different projects use different versions of python, depending on the version of the library is also different, in order to avoid version conflicts, so for each project each version of python to create a virtual environment, the environment used by dependent libraries also exist independently, will not be affected by other versions or other project libraries.

1. Create a separate folder to store pyqt5 code and create a virtual environment

I set up a folder called python on the F disk and a folder python-pyqt5 in this folder to store the code. At this time, the python-pyqt5 is empty and there are no files.

2. Enter pycharm and open the python-pyqt5 project

Step: click File-- > Click Open-- > find the folder you just created (python-pyqt5)-> Click OK

3. Configure the virtual environment

1. Click the Terminal below to enter the terminal (you must make sure that the path displayed on the terminal is the same as that of the folder)

two。 Enter on the terminal

This is to create a virtual environment.

Python-m venv venv

3. At this point, in the Project project, python-pyqt5 can see a folder called venv, which is the virtual environment.

Configure a virtual python environment

Step: 1. Click File-- > Settings

2. Find Project:python-pyqt5-- > Project Interpreter (project interpreter)-> Add (add interpreter)

3. Click Virtualenv Environment-- > Existing environment-- > Interpreter

The interpreter here chooses the path of the virtual interpreter we created, and finally includes python.exe

Click Ok all the way back to Project Interpreter (project interpreter), and you will find that the interpreter has now been created, and there are only two default libraries here. Finally, click Apply at the bottom right, and then click OK.

Never mind the "(2)" here, this is because I have created a second interpreter of this. If it is created for the first time, there is no "(2)" here.

Install pyqt5 and pyqt5-tools tools

When you open a terminal, you want to display the venv, so that the virtual interpreter is configured successfully, indicating that the current environment is a virtual environment.

This installation is the use of domestic sources, Douban network for installation, the installation speed will be very fast

1. Install: pyqt5pip install pyqt5-I https://pypi.douban.com/simple/

The appearance of Successfully means that the installation is successful and the yellow one is not needed. This is a warning and generally tells pip that it needs to be updated.

2. Install: pyqt5-toolspip install pyqt5-tools-I https://pypi.douban.com/simple/

4. Configure system environment variables

1. Click: control panel right-click-> Click system-> Advanced system Settings-> system variable-> Path

2. Open the interface from the folder to the virtual environment

Search here:

3. Search: designer.exe

4. Right-click-- > Open the location of the file

5. Copy the above path: F:\ python\ python-pyqt5\ venv\ Lib\ site-packages\ qt5_applications\ Qt\ bin

Add to the environment variable

6. Search again: plugins

7. Click the last file and right-click-- > go to the location of the file.

Click plugins to enter the folder:

8. Copy path: F:\ python\ python-pyqt5\ venv\ Lib\ site-packages\ PyQt5\ Qt5\ plugins

And add it to the system variable

Variable name: QT_QPA_PLATFORM_PLUGIN_PATH

Variable values: path

5. Configure Qt Designer

Enter pycharm, click File-- > click Settings-- > Tools-- > External Tools

Add the name of the extra component

Name:

Qt Designer

The path to the extra component, which is the path to designer.exe

Program::

F:\ python\ python-pyqt5\ venv\ Lib\ site-packages\ qt5_applications\ Qt\ bin\ designer.exe

Work path:

Method 1:

Working directory:

$FileDir$

Method 2:

Working directory:F:\ python\ python-pyqt5

Because I configured the first one to report an error, and the path did not exist, so I changed to the second method, filling in an actual path

Go to the initial interface and click as follows:

When the configuration is successful, the run will not report an error, and an interface will appear

The appearance of such an interface means that the Qt Designer is configured successfully.

6. Configure PyUIC

PyUIC: this is to encode the interface we set to the .py file.

Click File-- > click Settings-- > Tools-- > External Tools-- > click + again

Add the name of the extra component

Name:

PyUIC

Path to additional components

Program:

F:\ python\ python-pyqt5\ venv\ Scripts\ pyuic5.exe

Arguments:

$FileName$-o $FileNameWithoutExtension$.py-x

Work path:

Note: this work path should be consistent with the Qt Designer work path configured above.

Working directory:F:\ python\ python-pyqt5

After the configuration is successful, click on the following steps, and if the configuration is successful, a .py file will appear in the folder, which is a success.

Contents of .py file

VII. matters needing attention

1. The .ui file must be available before PyUIC conversion can be carried out, otherwise an error will be reported.

2. The environmental variables of the system must be correct.

3. The pyqt5 files according to different python may be different, but they are basically the same, except that the path of the file is different.
