如果你有任何建议，请尽快告诉我！
我正在尝试为conda设置开发环境。
我的参考：-开发环境，Windows cmd.exe shell
做了指定的一切git被设置为path.. etc
运行以下命令
set GITHUB_USERNAME=pravincoder
git clone https://github.com/pravincoder/conda.git "%CONDA_PROJECT_ROOT%"
cd "%CONDA_PROJECT_ROOT%"
git remote add %GITHUB_USERNAME% https://github.com/pravincoder/conda.git
