使用pip安装私人git repo的问题

Question

我正在尝试从我可以使用pip访问的私有存储库中安装软件包。

我能够直接克隆它。

但是当我尝试通过pip安装它时，出现以下错误：

  ERROR: Command errored out with exit status 128:
  command: git clone -q 'ssh://****@github.com/my_projects/ib_client' /tmp/pip-req-
  build-ivumdv23
  cwd: None
  Complete output (7 lines):
  key_load_public: invalid format
  Warning: Permanently added the ECDSA host key for IP address 'AA.BB.CC.DD' to the list 
  of known hosts.
  Permission denied (publickey).
  fatal: Could not read from remote repository.

  Please make sure you have the correct access rights
  and the repository exists.

  The command '/bin/sh -c python3 -m pip install --upgrade pip     && python3 -m pip install -q -r ${BASE_DIR}/requirements.txt     && python3 -m pip install -q -r ${BASE_DIR}/healthchecks/requirements.txt' returned a non-zero code: 1
  make: *** [build] Error 1

关于这一点，我已经浏览了Trouble installing private github repository using pip，Is it possible to use pip to install a package from a private GitHub repository?和Trouble installing private github repository using pip的帖子，但是我仍然不知道该如何解决。
