一.用PyInstaller打包PyQt5應用

二.使用PyQtGraph進行資料可視化

一.用PyInstaller打包PyQt5應用

打包時會自動將依賴庫都打打包進去！所以體積不小，，

安裝：pip3 install pyinstaller

代碼：

直接在命令列下操作

常用：pyinstaller -Fw python檔案名

pyinstaller -Fw Calc. py
-W:不顯示終端
-F:將所有的庫打包成-個單獨的檔案

bug：

 from importlib_metadata import PackagePath as _PackagePath
ImportError: cannot import name 'PackagePath' from 'importlib_metadata' (D:\anaconda\lib\site-packages\importlib_metadata\__init__.py)

現在pyinstaller是不支持python3.6的，正在完善中，所以可以去GitHub下載最新版的使用，戳這里

下開發版，

嘗試了開發版，還是同樣的錯誤！！！心態炸了！！！

看到一句話：一定要把pip升級成最新版的pip在安裝pyinstaller哈，要不然可能會出現莫名奇妙的問題，

試過之后，還是不行！！！！

早晨突然看見anaconda沒有被激活

于是開始激活,戳這里

激活之后重新打開cmd輸入python發現還是出警告，，，，

最后最后，發現是anaconda的問題，，，我換了一個python原生的編譯器下的pyinstaller沒問題，，，當然之前的問題我還是不會解決，，，

在我的原生python下裝上相應的包，再打包即可成功，會在當前目錄生成三個檔案夾和一個spec檔案，exe檔案在dist中

二.使用PyQtGraph進行資料可視化

代碼：

pyqtgraph_pyqt.py

# -*- coding: utf-8 -*-

# Form implementation generated from reading ui file 'pyqtgraph_pyqt.ui'
#
# Created by: PyQt5 UI code generator 5.9.2

        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.pyqtgraph1 = GraphicsLayoutWidget(self.centralwidget)
        self.pyqtgraph1.setGeometry(QtCore.QRect(10, 10, 721, 251))
        self.pyqtgraph1.setObjectName("pyqtgraph1")
        self.pyqtgraph2 = GraphicsLayoutWidget(self.centralwidget)
        self.pyqtgraph2.setGeometry(QtCore.QRect(10, 290, 501, 281))
        self.pyqtgraph2.setObjectName("pyqtgraph2")
        MainWindow.setCentralWidget(self.centralwidget)
        self.menubar = QtWidgets.QMenuBar(MainWindow)
        self.menubar.setGeometry(QtCore.QRect(0, 0, 800, 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)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)

    def retranslateUi(self, MainWindow):
        _translate = QtCore.QCoreApplication.translate
        MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
