我有一个名为的 Python 文件hello.py：

import openpyxl

def operate_excel():
    file = 'dummy.xlsx'
    new_row = ['data1', 'data2', 'data3', 'data4']

    wb = openpyxl.load_workbook(filename=file)
    ws = wb['Sheet1']     # Older method was  .get_sheet_by_name('Sheet1')
    row = ws.max_row + 1

    for col, entry in enumerate(new_row, start=1):
        ws.cell(row=row, column=col, value=entry)

    wb.save(file)

当我直接从 Python 运行它时，它可以工作。但是，当我尝试使用以下命令对其进行转码时，它失败了：

python3 -m transcrypt -b ./Codes/js_excel_operations/hello.py

此命令生成以下输出行：

那么，可能是什么问题？我错过了什么吗？

请参阅Transcrypt 文档中的第 1.3 节。简而言之，您通常会想要使用 JS 第三方库。

根本原因是 Transcrypt 无法将带有已编译组件的库转换为 JS。此外，在Transcrypt中，所有的标准库都没有实现，只有一些Essentials 。对于其他一切，请使用 JS 库。
