Conda PackagesNotFoundError

Question

我想在Conda中使用特定版本的Python创建新的环境，因此我可以下载仅适用于该Python版本的软件（Busco）。我用命令

conda create -n envname  python=3.3.0

but i got this error msg :

PackagesNotFoundError: The following packages are not available from
current channels:

  - python=3.3.0

Current channels:

  - https://conda.anaconda.org/bioconda/linux-64
  - https://conda.anaconda.org/bioconda/noarch
  - https://conda.anaconda.org/conda-forge/linux-64
  - https://conda.anaconda.org/conda-forge/noarch

以及更多类似的当前频道你能告诉我该怎么办

Answer 1

问题是，Python 3.3版本不再托管在conda-forge频道或bioconda频道上。您仍然可以使用以下方法在anaconda频道上获取它：

conda create -n envname python=3.3.0 -c anaconda
