【FireSim/Chipyard】解决FireSim Repo Setup步骤中Conda的firesim环境下载失败的问题

问题描述

按照U250官方文档下载Conda环境的时候，即语句./scripts/machine-launch-script.sh --prefix REPLACE_ME_USER_CONDA_LOCATION的时候会遇到以下报错：

Solving environment: ...working... failed with repodata from current_repodata.json, will retry with next repodata source. 
PackagesNotFoundError: The following packages are not available from current channels:- conda-lock=1.4*
Current channels:-  To search for alternate channels that may provide the conda package you're looking for, navigate tohttps://anaconda.org and use the search bar at the top of the page.Note: 'use_only_tar_bz2' is enabled. This might be omitting some
packages from the index. Set this option to 'false' and retry.

然后另开一个窗口执行conda env list命令发现只有base环境，没有firesim。

解决方法

我先执行了conda install requests命令，又换了源conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free 、conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main

最后参考PackagesNotFoundError的方法二，进入https://anaconda.org链接，找到conda-lock=1.4.0的条目，点进去使用它提供的指令单独下载conda install ctools::conda-lock，这一步实践会有一点点长，耐心等待一下。

执行完上述命令再执行文档中的./scripts/machine-launch-script.sh --prefix REPLACE_ME_USER_CONDA_LOCATION命令，会发现环境安装成功。
