我是python的新手,我在github上發現這個項目「https://github.com/jadsonbr/pyreport」,我想打印來自mysql服務器的發票。我安裝pyreport和jasperpy但是當我嘗試運行代碼我得到這個錯誤:pyreport和jasperpy,我運行代碼時出錯
Traceback (most recent call last):
File "E:/onedrive/Documents/optimpos/module/fact_print.py", line 36, in <module>
compiling()
File "E:/onedrive/Documents/optimpos/module/fact_print.py", line 9, in compiling
jasper = pyjasper.JasperPy()
AttributeError: 'module' object has no attribute 'JasperPy'
我fact_print.py看起來是這樣的:
import os,sys,subprocess
from platform import python_version
import pyjasper
sys.stderr = open("errlog.txt", "w")
def compiling():
input_file = os.path.dirname(os.path.abspath(__file__)) + \
'/Invoice_2.jrxml'
jasper = pyjasper.JasperPy()
jasper.compile(input_file)
def advanced_example_using_database():
input_file = os.path.dirname(os.path.abspath(__file__)) + \
'/Invoice_2.jrxml'
output = os.path.dirname(os.path.abspath(__file__)) + '/'
con = {
'driver': 'mysql',
'username': 'admin1',
'password': 'marcopolo',
'host': 'localhost',
'database': 'optimpos',
'schema': 'temp_vanzari',
'port': '3306'
}
jasper = pyjasper.JasperPy()
jasper.process(
input_file,
output_file=output,
format_list=["pdf", "rtf", "xml"],
parameters={'python_version': python_version()},
db_connection=con,
locale='en_US' # LOCALE Ex.:(en_US, de_GE)
)
print("done printing")
這可能是一個簡單的答案,但我不是能找到爲什麼pyjasper.JasperPy()
不起作用。我正在使用pyhton 2.7
這只是一個測試代碼,mysql服務器僅供測試。 需要一些幫助,謝謝
