我该如何解决这个问题？

Answer 1

尝试在命令提示符（管理员）上运行conda update conda

或转到您的anaconda 安装文件夹， right-click “ Anaconda3 ”，转到“ Security ，在“组或用户名”中单击“ Users ，然后选中“允许”下的所有内容。

Answer 2

不要在普通终端窗口中运行或以管理员身份运行，而是打开 anaconda 终端。

1. 在 Windows 10 搜索栏中，键入cmd （不要按 Enter）
2. 在结果中，您应该看到一个标题为“Anaconda prompt (anaconda 3)”的
3. 在这个 anaconda 终端中输入您的命令，例如conda update conda

Answer 3

您需要将以下行添加到您的（环境变量）路径中：

D:\Anaconda3\condabin

您需要将其添加D:\\Anaconda3和D:\\Anaconda3\\Scripts ，这样，当你调用conda ，它将执行conda.bat从D:\\Anaconda3\\condabin ，而不是conda.exe从D:\\Anaconda3\\Scripts ，这将为您提供正确的权限。
