Question

我有这个要转换为可执行文件的有效py文件。我使用pyinstaller来做到这一点，具体来说，我使用了此命令

pyinstaller --onefile --windowed --icon=images.ico file.py

实际上，它在dist文件夹中创建了一个可执行文件。但是，当我运行此可执行文件时，会发生错误，显示“无法执行脚本”或有时什么也没有发生。如何成功转换并运行

注意：py文件包含pyqt5和pandas模块。以下是py文件。

import os, sys

from PyQt5.QtWidgets import QApplication, QWidget, QLineEdit, QLabel,QVBoxLayout, QHBoxLayout,QPushButton, QMessageBox from PyQt5

    def __init__(self):

        self.initUI()

        self.setFixedSize(400, 650)
        self.setWindowIcon(QIcon('images.png'))

        label_input = QLabel("Enter the filename of CSV that you want edit:")
        label_input.setFont(QtGui.QFont("Times", 18))
        self.input = QLineEdit(self)
        self.input.setFont(QtGui.QFont("Times", 18))

            if input_file == "":
                QMessageBox.information(self, "Message", "Please choose a file!")
                return
            elif os.path.exists(input_file) == False:
                QMessageBox.about(self, "titt!", "File does not exist")
                return
            else:
                df = pd.read_csv(self.input.text())
                df = df.sort_values(["strLocal", "strTide"])
                df['strLocal'] = pd.to_datetime(df.strLocal)
                df['strLocal'] = df['strLocal'].dt.strftime('%m/%d/%Y %H:%M:%S')
                df['strTide'] = df.strTide / 1000 * 0.1
                df[['Date','Time']] = df.strLocal.str.split(" ",expand=True)
                cols = df.columns.tolist()
                cols = cols[2:] + [cols[1]]
                df = df[cols]
                print(df)
                df.to_csv(output_file,index = False, header = False)
                QMessageBox.about(self, "titt!", "Done. " + output_file + " was created.")

        but_edit.clicked.connect(edit_csv)
        
    def initUI(self):
        self.setWindowTitle(self.title)
        self.setGeometry(self.left, self.top, self.width, self.height)
        self.show()
     if __name__ == '__main__':
    app = QApplication(sys.argv)
    ex = App()
    sys.exit(app.exec_())

为什么将我转换为exe的py无法运行？
