python - python /畅达/ python /Windows : how to start and activate a conda environment?

Question

我通过 Anaconda 安装了 Python 3.5 (3.5.6)，现在我希望能够使用 Python 3.7，将 3.5 保持为默认值(一个 python "insert script name" 将在命令行上运行)。我命令计算机激活它，但它不工作。

在“开始”菜单中，您必须打开“Anaconda Prompt”，它不同于普通的“命令提示符”。您的环境从那里被激活。然后执行 activate <env-name>
