【问题描述】：

我有一个通过代理服务器访问 Internet 的程序，我正在使用 PyPac 的 PACSession 进行会话。当我用 python 调用程序时，这很好用。但是，用 pyinstaller 编译它会给我一个错误。

测试程序：

import sys
import os
from pypac import PACSession
from requests.auth import HTTPProxyAuth
import getpass
import keyring
url = r'https://leilookup.gleif.org/api/v1/leirecords?lei='
lei_list = ['I9O8MELCUVOTLJABOX92', '5493004NRE4TCTRC2D29', 'VBHFXSYT7OG62HNT8T76', '529900M2YBAPOUTTM178', '549300KJFL0KHN20KH82',
            '0NTV4GLMGXKW55GJC835']

def main():
    lei_numbers = ",".join(lei_list)
    internet = 'gleif.org'
    password = keyring.get_password(internet, getpass.getuser())
    if not password:
        keyring.set_password(internet, getpass.getuser(), getpass.getpass('Please enter your Login password: '))
    print('Before PACSession')
    session = PACSession(proxy_auth=HTTPProxyAuth(getpass.getuser(), keyring.get_password(internet, getpass.getuser())))
    page = session.get(url=url + lei_numbers)
    json = page.json()
    for ix in range(len(json)):
        print(json[ix]['LEI']['$'] + ': ' + json[ix]['Entity']['LegalName']['$'])

    return 0

if __name__ == "__main__":
    sys.exit(main())

版本：

Windows 7
python 3.6.3 
pypack 0.5.0
pyinstaller 3.3
requests 2.18.4
tld 0.7.9;

如何使编译后的程序与 pyinstaller 一起工作？

【解决方案1】：

您的实际问题是：

FileNotFoundError: [Errno 2] No such file or directory: '...\\AppData\\Local\\Temp\\_MEI299882\\tld\\res\\effective_tld_names.dat.txt'

基本上，pypac 使用的 tld 包会加载该文本文件，并且一旦使用 PyInstaller 打包，该文件就不再可用。您可以使用规范文件中的 --add-data 标志或 datas 字段将其包含在 PyInstaller 二进制文件中。

datas: [('C:\Python\Lib\site-packages\tld\res\effective_tld_names.dat.txt', 'tld\res')]

【讨论】：

字符串也应该有 r"some string" 前缀

【解决方案2】：

如果您尝试从上面的答案中复制粘贴解决方案，则尝试此操作并确保适当更改您的 python 路径

datas= [('C:\\Python\\Lib\\site-packages\\tld\\res\\effective_tld_names.dat.txt', 'tld\\res')]
