【问题描述】：
我正在尝试从一个 yml 文件创建一个 conda 环境，我过去可以使用该文件创建环境并将其用作我的解释器。 （操作系统：Windows 64 - Python 到 Anaconda - IDE：VS Code）
我不得不多次删除这个环境并重新创建它，因为这个环境中添加了新的依赖项（conda env update --prefix ./env --file environment.yml --prune 不起作用）。我还必须从环境中手动删除一些 dll 文件。
到目前为止，环境创建工作。过了一会，再次创建环境，报错UserWarning: mkl-service package failed to import, therefore Intel(R) MKL initialization ensuring its correct out-of-the box operation under condition when Gnu OpenMP had already been loaded by Python process is not assured. Please install mkl-service package, see http://github.com/IntelPython/mkl-service，但是yml文件中包含了mkl-service。
我从C:\Users\Anaconda3\envs 中删除了环境并手动删除了整个文件夹。现在，当我尝试在 VS 代码终端中创建环境时，我收到错误报告：

我猜我在某个地方犯了一个致命的错误，但不知道在哪里。任何想法或解决方案将不胜感激。
