1.安裝pythom（略）

2.安裝pycharm（略）

3.安裝pyqt5 designer漢化

3.1首先是安裝pyqt5

pip install PyQt5

出現錯誤:

ERROR: THESE PACKAGES DO NOT MATCH THE HASHES FROM THE REQUIREMENTS FILE. If you have updated the package versions, please update the hashes. Otherwise, examine the package contents carefully; someone may have tampered with them.
    PyQt5 from https://files.pythonhosted.org/packages/1f/0e/d0390f7ac55c3d4ac041cbdb13fa2b03225a7f8856d52f712e7e398b2208/PyQt5-5.13.2-5.13.2-cp35.cp36.cp37.cp38-none-win32.whl#sha256=14737bb4673868d15fa91dad79fe293d7a93d76c56d01b3757b350b8dcb32b2d:

             Got        c2886891b8915741ee3103cec3156d5282b22e5766187151b139e2044cedb248

WARNING: You are using pip version 19.2.3, however version 19.3.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

 輸入

python -m pip install --upgrade pip

再輸入

pip install PyQt5

安裝成功！

3.2 安裝Qt工具

pip install PyQt5-tools

出現下面錯誤

ERROR: Could not find a version that satisfies the requirement PyQt5-tools (from versions: none)
ERROR: No matching distribution found for PyQt5-tools

解決方法如下：

https://pan.baidu.com/s/1GVhquhTe5bgrjGRvUVRloQ 提取碼:ain0 
或者https://github.com/xdd1997/Download-or-Picture/blob/master/PyQt5_Tools-5.7.dev1-py3-none-any.whl

下載后得到一個.whl文件
將上面文件放在'C:\Windows\SysWOW64\ 目錄下

WIN+R輸入cmd，回車打開命令提示符:
輸入：pip install wheel
然后：pip install PyQt5_Tools-5.7.dev1-py3-none-any.whl
至此就成功安裝了pyqt5-tools

安裝完成之后先確認一下安裝位置，因為之后用的上，正常的話，會在你的python的安裝目錄下的

\pythonx.x\Lib\site-packages目錄下，如圖：

3.3 安裝安裝QtDesigner

然后進入pycharm的File下的settings->Tools->External Tools 點加號，

Name：QtDesigner　　
Program：之前PyQt5-tools目錄下的designer.exe文件 如我的E:\Python38\Lib\site-packages\PyQt5-tools\designer\designer.exe
2020-06-14更新：E:\Program Files\python3.7.4\Lib\site-packages\pyqt5_tools\Qt\bin\designer.exe
Working directory:$FileDir$

3.4安裝PyUIC

進入pycharm的File下的settings->Tools->External Tools 點加號，

Name：PyUIC　　
Program：選擇python.exe的文件路徑 如我的：E:\Python38\python.exe

Argument：
-m
PyQt5.uic.pyuic
$FileName$
-o
$FileNameWithoutExtension$.py

Working directory:$FileDir$

3.5安裝PyRCC

進入pycharm的File下的settings->Tools->External Tools 點加號，

Name：PyRCC　　
Program：python目錄下的Script下的pyrcc5.exe的目錄

Argument：
$FileName$
-o
$FileNameWithoutAllExtensions$.py

Working directory:$FileDir$

3.6 designer漢化

over,over,over!

代碼測試

 

import sys
from PyQt5.QtWidgets import*
if __name__=='__main__':
    #創建QApplication實例
    app = QApplication(sys.argv)
    #創建一個窗口
    w = QWidget()
    #設置窗口尺寸
    w.resize(300,150)
    #移動窗口
    w.move(300,300)
    #設置窗口標題
    w.setWindowTitle('第一個基於PyQt5的桌面應用')
    #顯示窗口
    w.show()
    #進入程序的主循環，並通過exit函數確保主循環安全結束
    sys.exit(app.exec_())

 

能顯示窗口則正常，有問題再花些時間改改吧
