Question

我面临一个相当奇怪的问题。我试图在python脚本中运行.js脚本。在我的.js脚本中，我将.pdf转换为json，然后在.py脚本中调用此.js脚本，将此json转换为.xlsx。

但是使用Popen执行.js脚本时会出现错误：＆＃34; [WinError 2]系统无法找到指定的文件＆＃34;。我现在已经将错误位置重新检查了近10次。我也检查了cwd是否正确。除了这个错误，一切都已到位。请帮我。：（

import pandas as pd
from subprocess import Popen, PIPE
import os

cwd = os.getcwd()
bankType = "parsePmc"
parser_path = os.path.join(cwd, "parse_pmc_bank_pdf.js")
input_file_path = os.path.join(cwd, "bs.pdf")
output_file_path = os.path.join(cwd, "bs_excel.xlsx")
print(parser_path)
print(input_file_path)
print(output_file_path)
#parser_path = parser_path.replace("\\","\\\\") #(Even this doesn't work.)
print(parser_path)
args = ["node", parser_path, input_file_path, output_file_path] #I've even checked it using with str() for the paths.
print(os.getcwd())
p = Popen(args, stdout=PIPE, stderr=PIPE)
stdout, stderr = p.communicate()
print(stdout)
if bool(stderr):
    print(stderr)
else:
    df = pd.read_json(output_file_path)
    if df.empty:
        print("EMPTY XLSX")
    else:
        df.to_excel(output_file_path, sheet_name='Raw')
