使用pyinstaller打包python文件后如何修复与NUMPY软件包有关的错误

Question

我已经编写了将xlsx转换为csv的代码，然后将其内容写入CSD文件，作为CICS活动的一部分。

当我在pycharm中执行代码时，它的工作正常。我使用pyinstaller的--oneFile选项打包了python文件，并发布了我在执行.exe文件时遇到的错误。错误是：

ImportError：缺少必需的依赖项['numpy']

我尝试在pycharm中运行相同的代码，它工作正常。但是我需要将此文件作为exe交付给我们的一位客户

import csv
import sys
import os
import pandas as pd




def xls2csv (xls_filename, csv_filename):
    global  excelFile
    df = pd.read_excel(xls_filename)  # sheetname is optional
    df.to_csv(csv_filename, index=False)
    excelFile = 1


def detectDelimiter(csvFile):
    with open(csvFile, 'r') as myCsvfile:
        header=myCsvfile.readline()
        if header.find(";")!=-1:
            return ";"
        if header.find(",")!=-1:
            return ","
    #default delimiter (MS Office export)
    return ";"


def ReadFile(csvFileName):
    global mydict
    with open(csvFileName, mode='r') as infile:
