我有一个 rhel 服务器，我将其用作其他服务器的 yum 存储库。现在我也需要它来提供 python 包。我找到了一个 anaconda 存储库来下载软件包：https://repo.continuum.io/pkgs/main/linux-64/我使用以下命令下载所有软件包：
wget -A bz2 https://repo.continuum.io/pkgs/main/linux-64/ -P /path_for_packages
我使用 -A bz2 因为所有包都是 tar.bz2 格式的。
我还有一台无法连接到互联网但可以与存储库服务器通信的客户端计算机。
目的是将软件包从服务器计算机安装/下载到客户端计算机。
我在两台服务器上都有 anaconda 4.5.11。我还在客户端计算机的“.condarc”文件中指定了通道（客户端查找包的路径）。
# This is a sample .condarc file.
# It adds the r Anaconda.org channel and enables
# the show_channel_urls option.
# channel locations. These override conda defaults, i.e., conda will
# search *only* the channels listed here, in the order given.
# Use "defaults" to automatically include all default channels.
# Non-url channels will be interpreted as Anaconda.org usernames
# (this can be changed by modifying the channel_alias key; see below).
# The default is just 'defaults'.
channels:
- http://<IP_ADDRESS>/Path/To/Packages
# Show channel URLs when displaying what is going to be downloaded
# and in 'conda list'. The default is False.
show_channel_urls: True
# For more information about this file see:
# https://conda.io/docs/user-guide/configuration/use-condarc.html
当我尝试使用上面的命令从客户端计算机安装软件包时：
conda install wget
Solving environment: failed

我尝试过的方法：
https://github.com/conda/conda/issues/7524
我还尝试将我的 anaconda 版本降级到“4.3.30”。这个版本给我带来了一个新的错误，它是：
conda install anaconda
Fetching package metadata .....
CondaEnvironmentNotFoundError: Could not find environment: /root/anaconda3/envs/base .
You can list all discoverable environments with `conda info --envs`.
从这个错误来看，它表明 repo 服务器没有这样的环境，即：
http://<IP_Address>/Path/To/Packages
我不知道是否可以将远程环境添加到这里。我尝试过，因为这是添加环境的方法：
conda --set custom_channels.my-conda-channel http://<IP_Address>/Path/To/Package
但正如我所假设的，它只能添加本地路径。
答案1
Anaconda 版本有问题。使用最新版本，Windows机器无法从远程存储库安装所需的数据包。您需要下载anaconda3-5.0.1安装程序exe才能解决此问题。
