python - UnavailableInvalidChannel : The channel is not accessible or is invalid. 错误代码 : 403, conda-forge 不工作

Question

即使在创建新环境时，我的 conda-forge 也无法正常工作并显示以下错误:

(base) C:\Users\1836849\Documents\GitHub_Repository\ChemOS-master>conda create -n py36 python=3.6
Collecting package metadata (current_repodata.json): failed

UnavailableInvalidChannel: The channel is not accessible or is invalid.
  channel name: conda-forge
  channel url: https://conda.anaconda.org/conda-forge
  error code: 403

You will need to adjust your conda configuration to proceed.
Use `conda config --show channels` to view your configuration's current state,
and use `conda config --show-sources` to view config file locations.

我的 conda info显示此信息:

可能的解决方案是什么？

Answer 1

根据文档 here收到此错误有几个可能的原因:

用户在他们的配置中错误地配置了他们的 channel (例如，存储 token 的安全位置被意外删除(最常见)

防火墙或其他安全设备或系统阻止用户访问(第二常见)

由于潜在的服务条款违规(第三常见)，他们阻止了他们的访问

解决方案
首先，运行以下命令来撤消您对商业版的配置: conda config --remove-key default_channels接下来，安装或升级 conda-token 工具: conda install --freeze-installed conda-token最后，重新应用 token 和配置设置:

# Replace <TOKEN> with your token
conda token set <TOKEN>
