Python3.6：_unify_values 中的文件“/usr/lib/python3.6/configparser.py”，第 1138 行

Question

我的腳本在使用 python 3.6 的 Pycharm 上運行良好，但是當我使用 Python3.6 從 ubuntu 16 運行時遇到了一些問題

錯誤：

python3.6 AttributeInsertion.py 正在加載庫模塊...回溯（最近一次調用）：文件“/usr/lib/python3.6/configparser.py”，第 1138 行，在 _unify_values sectiondict = self._sections[section] KeyError ：'測試配置'

這里變量“configfilename”中提供的路徑沒有指向 config.ini 文件的確切位置。 默認目錄可以根據環境/服務器/模塊/等而不同； 這不是您的程序所在的目錄。 因此，您可以使代碼指向文件所在的當前目錄。

您可以嘗試導入操作系統模塊（導入操作系統）並在您的變量“configfilename”中進行以下更改，該變量指向“resources”目錄下的“config.ini”文件。

configfilename = (os.path.join(os.path.dirname(__file__),'resources','config.ini'))
