使用 conan 安装包需要账号密码吗？

Question

我在源码编译 milvus

git clone [e-mail]:milvus-io/milvus.git
cd milvus
pip install conan==1.58.0
make build

然后要我输入账号？

我之前从来没有用过 conan

有谁用过 conan？

conan 安装任何东西都需要账号密码？还是安装特定东西才需要账号密码？

如果是「安装特定东西」需要账号密码，那这是什么东西？

Answer 1

不一定，私有仓库，上传包，特定的公共仓库这些都要登录，folly/2023.07.12@milvus/dev你这个以来不在conancenter公共仓库里，在default-conan-local 仓库里这是一个私有仓库，所以要你登录
