[Python知识库]anaconda-navigator界面无法启动，loading application，报ERROR download_api._get_url 错误

原先安装的anaconda3,今天突然没法启动了，卡在了loading application的界面，懵逼了会，卸载重装，情况一样，网上搜索根据此文章的帮助（https://blog.csdn.net/tanmx219/article/details/88069375），找到问题。报错如下：

原因和上文连接分析的一样，主要是vscode_application_data()中的self._VSCODE_ENDPOINT获取的vscode地址错误（https://vscode-update.azurewebsites.net/api/update/win32-x64/stable/version）不能访问导致，正确的地址为：https://update.code.visualstudio.com/api/update/win32-x64/stable/version

解决方法：在anaconda_api.py中搜索

        VSCODE_ENDPOINT = (
            'https://vscode-update.azurewebsites.net/api/update'
            '/{}/stable/version'.format(VSCODE_SUBDIR)
        )

把链接改为：

        VSCODE_ENDPOINT = (
            'https://update.code.visualstudio.com/api/update'
            '/{}/stable/version'.format(VSCODE_SUBDIR)
        )

保存文件，重启anaconda-navigator解决问题
