macOS+Python3+pycharm 安装PyQt5、配置QtDesigner、UI转换工具图文详解

环境如下：
Mac OS 10.13.6 版本
Pycharm 10.13.6 社区版
python 3.6.6 版本
PyQt5 5.13.0版

1. 进入虚拟环境并激活（不需要在虚拟环境的跳过第一步）
   $ cd /Users/***/PycharmProjects/pyqt/env
$ source bin/activate
2. 进入Pycharm搜索安装SIP、PyQt5或者命令行输入pip3 install SIP接着输入pip3 install PyQt5
3. 安装Qt
   brew install qt
4. 在Pycharm配置QtDesigner，可以可视化操作的工具。
   
   Program：找到自己电脑里的Designer.app对应的路径
   打开终端输入：
   find ~ -iname "Designer.app"
   查看Designer.app的显示简介并复制路径
   eg： /usr/local/Cellar/qt/5.13.0/libexec/Designer.app
   Working directory:点击insert Macro…添加$FileDir$
5. 添加pyUIC能把UI文件转成py文件
   
   Program：找到自己工程使用的python对应的路径
   eg： /Users/***/PycharmProjects/pyqt/env/bin/python
   Paramters里面的内容：(一样）
   -m PyQt5.uic.pyuic $FileName$ -o $FileNameWithoutExtension$.py
   Working directory:添加$FileDir$
   点击Ok，apply
   
   打开QtDesigner。
   
   pyUIC这个命令行工具会把UI文件转成py文件
   
   

如果上面觉得麻烦的话

可以保存下面这个脚本，也能将.ui文件转换为.py文件,同一个文件夹下的所有.ui文件一次转换成.py文件

import os
import os.path

dir = './'
def listUiFile():
    list = []
    files = os.listdir(dir)
    for filename in files:
        # print( dir + os.sep + f  )
        # print(filename)
        if os.path.splitext(filename)[1] == '.ui':
            list.append(filename)
    return list

def transPyFile(filename):
    return os.path.splitext(filename)[0] + '.py'

def runMain():
    list = listUiFile()
    for uifile in list:
        pyfile = transPyFile(uifile)
        cmd = 'pyuic5 -o {pyfile} {uifile}'.format(pyfile=pyfile, uifile=uifile)
        # print(cmd)
        os.system(cmd)
        
if __name__ == "__main__":
    runMain()

6. Qt第一个界面，运行试一下
   新建demo1.py

from PyQt5 import QtCore, QtGui, QtWidgets

class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(708, 600)
        MainWindow.setStyleSheet("background:rgb(20, 142, 198)")
        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.frame1_3 = QtWidgets.QFrame(self.centralwidget)
        self.frame1_3.setGeometry(QtCore.QRect(60, 140, 531, 271))
        self.frame1_3.setStyleSheet("background:rgb(53,144,250);")
        self.frame1_3.setFrameShape(QtWidgets.QFrame.StyledPanel)
        self.frame1_3.setFrameShadow(QtWidgets.QFrame.Raised)
        self.frame1_3.setObjectName("frame1_3")
        self.frame1_2 = QtWidgets.QFrame(self.frame1_3)
        self.frame1_2.setGeometry(QtCore.QRect(130, 130, 293, 49))
        self.frame1_2.setStyleSheet(" border-style:none;")
        self.frame1_2.setFrameShape(QtWidgets.QFrame.StyledPanel)
        self.frame1_2.setFrameShadow(QtWidgets.QFrame.Raised)
        self.frame1_2.setObjectName("frame1_2")
        self.horizontalLayout_2 = QtWidgets.QHBoxLayout(self.frame1_2)
        self.horizontalLayout_2.setObjectName("horizontalLayout_2")
        self.label_3 = QtWidgets.QLabel(self.frame1_2)
        self.label_3.setStyleSheet("color:rgb(255, 255, 255);")
        self.label_3.setObjectName("label_3")
        self.horizontalLayout_2.addWidget(self.label_3)
        self.lineEdit_2 = QtWidgets.QLineEdit(self.frame1_2)
        self.lineEdit_2.setStyleSheet("background:rgb(255, 255, 255);height:30;")
        self.lineEdit_2.setObjectName("lineEdit_2")
        self.horizontalLayout_2.addWidget(self.lineEdit_2)
        self.frame1 = QtWidgets.QFrame(self.frame1_3)
        self.frame1.setGeometry(QtCore.QRect(130, 80, 293, 49))
        self.frame1.setStyleSheet(" border-style:none;")
        self.frame1.setFrameShape(QtWidgets.QFrame.StyledPanel)
        self.frame1.setFrameShadow(QtWidgets.QFrame.Raised)
        self.frame1.setObjectName("frame1")
        self.horizontalLayout = QtWidgets.QHBoxLayout(self.frame1)
        self.horizontalLayout.setObjectName("horizontalLayout")
        self.label_2 = QtWidgets.QLabel(self.frame1)
        self.label_2.setStyleSheet("color:rgb(255, 255, 255);")
        self.label_2.setObjectName("label_2")
        self.horizontalLayout.addWidget(self.label_2)
        self.lineEdit = QtWidgets.QLineEdit(self.frame1)
        self.lineEdit.setStyleSheet("background:rgb(255, 255, 255);height:30;")
        self.lineEdit.setObjectName("lineEdit")
        self.horizontalLayout.addWidget(self.lineEdit)
        self.click = QtWidgets.QPushButton(self.frame1_3)
        self.click.setGeometry(QtCore.QRect(230, 200, 113, 32))
        self.click.setStyleSheet("color:rgb(255, 255, 255);background:rgb(128, 255, 7);")
        self.click.setObjectName("click")
        MainWindow.setCentralWidget(self.centralwidget)
        self.menubar = QtWidgets.QMenuBar(MainWindow)
        self.menubar.setGeometry(QtCore.QRect(0, 0, 708, 22))
        self.menubar.setObjectName("menubar")
        MainWindow.setMenuBar(self.menubar)
        self.statusbar = QtWidgets.QStatusBar(MainWindow)
        self.statusbar.setObjectName("statusbar")
        MainWindow.setStatusBar(self.statusbar)

        self.retranslateUi(MainWindow)
        self.click.clicked.connect(MainWindow.close)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)

    def retranslateUi(self, MainWindow):
        _translate = QtCore.QCoreApplication.translate
        MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
        self.label_3.setText(_translate("MainWindow", "密码   "))
        self.label_2.setText(_translate("MainWindow", "用户名"))
        self.click.setText(_translate("MainWindow", "登录"))

新建main.py

import sys
import demo1
from PyQt5.QtWidgets import QApplication, QMainWindow
if __name__ == '__main__':
    app = QApplication(sys.argv)
    MainWindow = QMainWindow()
    ui = demo1.Ui_MainWindow()
    ui.setupUi(MainWindow)
    MainWindow.show()
    sys.exit(app.exec_())

运行main.py看看成功安装成功没有
