FileNotFoundError: [Errno 2] No such file or directory - 無法解決路徑問題

Question

我有這個問題，我正在嘗試運行腳本來下載 Springers 免費書籍 [ https://towardsdatascience.com/springer-has-released-65-machine-learning-and-data-books-for-free-961f8181f189 ] ，但很多事情開始到 go 錯誤。 我解決了一些問題，但現在我被卡住了。

FileNotFoundError: [Errno 2] No such file or directory: 'downloads\\table_v4.xlsx'

這是代碼的一部分，介紹了 table_path。

table_url = 'https://resource-cms.springernature.com/springer-cms/rest/v1/content/17858272/data/v4'

table = 'table_' + table_url.split('/')[-1] + '.xlsx'
table_path = os.path.join(folder, table)
if not os.path.exists(table_path):
    books = pd.read_excel(table_url)
    # Save table
    books.to_excel(table_path)
else:
    books = pd.read_excel(table_path, index_col=0, header=0)

Answer 1

嘗試在調用.to_excel()之前創建目標目錄，以確保存在有效的可寫目錄。 確保os模塊已導入：

import os      # add to your imports

並更換

    books.to_excel(table_path)

和

    os.makedirs(folder, exist_ok=True)
    books.to_excel(table_path)
