正如标题所示,我试图从私有GitHub存储库安装Python包.对于公共存储库,我可以发出以下命令,该命令正常工作：

pip install git+git://github.com/django/django.git

但是,如果我尝试使用私有存储库：

pip install git+git://github.com/echweb/echweb-utils.git

我得到以下输出：

Downloading/unpacking git+git://github.com/echweb/echweb-utils.git
Cloning Git repository git://github.com/echweb/echweb-utils.git to /var/folders/cB/cB85g9P7HM4jcPn7nrvWRU+++TI/-Tmp-/pip-VRsIoo-build

我想这是因为我试图访问私有存储库而不提供任何身份验证.因此我尝试使用Git ssh希望pip使用我的SSH公钥进行身份验证：

pip install git+ssh://github.com/echweb/echweb-utils.git

这给出了以下输出：

Downloading/unpacking git+ssh://github.com/echweb/echweb-utils.git

我想要实现的是什么？如果是这样,我该怎么办？
