python請求在轉換爲.exe時找不到帶有證書的文件夾

Question

我有一個程序可以將來自不同市場營銷系統的廣告統計信息進行集中。一切工作正常，直到我將它轉換爲.exe格式並運行它。

OSError: Could not find a suitable TLS CA certificate bundle, invalid path: C:\Users\user\AppData\Local\Temp\_MEI253762\facebookads\fb_ca_chain_bundle.crt 

我試圖通過使用此代碼來解決這個問題，但MEI文件夾不斷變化的數字，每次我運行此代碼，以便它是沒有用的。

dst = r'C:\Users\user\AppData\Local\Temp\_MEI120642\facebookads' 
file = 'fb_ca_chain_bundle.crt' 

try: 
    os.makedirs(dst); ## it creates the destination folder 
except: 
    pass 

shutil.move(file, dst) 

讓我去這個文件

C：\用戶\用戶\應用程序數據\本地\程序\ Python的\ Python35 \ LIB \站點包\請求\ adapters.py

和試圖評論是否引發這種錯誤，但得到了SSL錯誤的語句。我找不到負責生成這些MEI數字的代碼。

我也遇到了這個問題。它看起來像來自程序編譯時沒有包含在requests軟件包目錄中的證書包cacert.pem。 requests模塊使用函數certifi.core.where來確定cacert.pem的位置。覆蓋此函數並覆蓋由此函數設置的變量似乎可以解決問題。

我將此代碼添加到我的節目的開頭：

import sys, os 


def override_where(): 
    """ overrides certifi.core.where to return actual location of cacert.pem""" 
    # change this to match the location of cacert.pem 
    return os.path.abspath("cacert.pem") 


# is the program compiled? 
if hasattr(sys, "frozen"): 
    import certifi.core 

    os.environ["REQUESTS_CA_BUNDLE"] = override_where() 
    certifi.core.where = override_where 

    # delay importing until after where() has been replaced 
    import requests.utils 
    import requests.adapters 
    # replace these variables in case these modules were 
    # imported before we replaced certifi.core.where 
    requests.utils.DEFAULT_CA_BUNDLE_PATH = override_where() 
    requests.adapters.DEFAULT_CA_BUNDLE_PATH = override_where()
