`conda install` 报告找不到 `conda search` 找到的包？

我在尝试安装软件包时收到此错误：

(pybert-tst)
dbanas@Davids-MacBook-Pro:~/Documents/Projects/PyBERT
$ conda install -c dbanas pybert
WARNING: The conda.compat module is deprecated and will be removed in a future release.
Collecting package metadata: done

UnsatisfiableError: The following specifications were found to be in conflict:
  - pybert
Use "conda search <package> --info" to see the dependencies for each package.

但是，我看到pybert当我搜索时包：

(pybert-tst)
dbanas@Davids-MacBook-Pro:~/Documents/Projects/PyBERT
$ conda search -c dbanas pybert --info

有谁知道发生了什么事吗？

这是由两个依赖项引起的pybert包被锁定为 Python 2.7，而 Python 本身则调用 Python 3.7。

如果我能在错误消息中看到其他两个包的名称，我当然会很高兴。 :(
