Python- Openpyxl 在控制台中工作但无法导入

Question

我在让 openpyxl 写入 Excel 文件时遇到问题，当我运行在 PyCharm Python 控制台中输入以下代码时它工作正常但是当我创建 & 运行 .py 文件时，出现以下错误：

C:\Users\David\PycharmProjects\VirtualEnv1\VirtualEnv1\Scripts\python.exe C:/Python27/virtualenv-15.0.1/virtualenv/test.py Traceback (most recent call last): File "C:/Python27/virtualenv-15.0.1/virtualenv/test.py", line 1, in from openpyxl import Workbook File "C:\Users\David\PycharmProjects\VirtualEnv1\VirtualEnv1\lib\site-packages\openpyxl__init__.py", line 28, in from openpyxl.workbook import Workbook File "C:\Users\David\PycharmProjects\VirtualEnv1\VirtualEnv1\lib\site-packages\openpyxl\workbook__init__.py", line 5, in from .workbook import * File "C:\Users\David\PycharmProjects\VirtualEnv1\VirtualEnv1\lib\site-packages\openpyxl\workbook\workbook.py", line 7, in from openpyxl.worksheet import Worksheet File "C:\Users\David\PycharmProjects\VirtualEnv1\VirtualEnv1\lib\site-packages\openpyxl\worksheet__init__.py", line 4, in from .worksheet import * File "C:\Users\David\PycharmProjects\VirtualEnv1\VirtualEnv1\lib\site-packages\openpyxl\worksheet\worksheet.py", line 34, in from openpyxl.cell import Cell File "C:\Users\David\PycharmProjects\VirtualEnv1\VirtualEnv1\lib\site-packages\openpyxl\cell__init__.py", line 4, in from .cell import * File "C:\Users\David\PycharmProjects\VirtualEnv1\VirtualEnv1\lib\site-packages\openpyxl\cell\cell.py", line 44, in from openpyxl.styles import numbers, is_date_format File "C:\Users\David\PycharmProjects\VirtualEnv1\VirtualEnv1\lib\site-packages\openpyxl\styles__init__.py", line 4, in from openpyxl.descriptors import Typed File "C:\Users\David\PycharmProjects\VirtualEnv1\VirtualEnv1\lib\site-packages\openpyxl\descriptors__init__.py", line 4, in from .base import * File "C:\Users\David\PycharmProjects\VirtualEnv1\VirtualEnv1\lib\site-packages\openpyxl\descriptors\base.py", line 12, in from openpyxl.xml.functions import Element File "C:\Users\David\PycharmProjects\VirtualEnv1\VirtualEnv1\lib\site-packages\openpyxl\xml\functions.py", line 41, in from xml.etree.ElementTree import ( ImportError: No module named etree.ElementTree Process finished with exit code 1

我从 https://openpyxl.readthedocs.org/en/default/index.html 安装并按照建议使用虚拟环境。我也下载了 elementtree 包到虚拟环境，但脚本仍然失败。任何帮助将不胜感激，谢谢！

from openpyxl import Workbook

wb = Workbook()
ws1 = wb.create_sheet()
ws1.title = "worksheet1"

c = ws1['A4']

ws1['A4'] = 15

cell_range = ws1['A1':'C2']

for row in ws1.iter_rows('A1:C2'):
    for cell in row:
        print cell

wb.save('balances.xlsx')

Console run

Answer 1

您的脚本在哪里使用 etree.ElementTree？这在控制台中对我很有用：

$ virtualenv .venv
$ . .venv/bin/activate
$ pip install openpyxl

$ tee test.py << 'EOF'
from openpyxl import Workbook

wb = Workbook()
ws1 = wb.create_sheet()
ws1.title = "worksheet1"

c = ws1['A4']

ws1['A4'] = 15

cell_range = ws1['A1':'C2']

for row in ws1.iter_rows('A1:C2'):
    for cell in row:
        print cell

wb.save('balances.xlsx')

EOF

$ python test.py

通过创建新的 PyCharm 虚拟环境并且不选中 "Inherit global site packages" 复选框解决了该问题：
