使用pip --index-url/--extra-index-url从GitLab装包遇404错误求助

我们使用私有GitLab Enterprise实例存储Python模块，参考《Package Registry中的PyPI包》文档。此前在容器中使用以下命令安装不同GitLab项目的私有包：

pip install <package_name_01> <package_name_02> \
    --index-url https://<personal_access_token_name_package_01>:<personal_access_token_package_01>@gitlab.example.com/api/v4/projects/<project_id_package_01>/packages/pypi/simple \
    --extra-index-url https://<personal_access_token_name_package_02>:<personal_access_token_package_02>@gitlab.example.com/api/v4/projects/<project_id_package_02>/packages/pypi/simple 

该方案之前正常运行，但近日执行时出现如下HTTP 404错误：

pip install <package_name_01> <package_name_02> \
> --index-url https://<personal_access_token_name_package_01>:<personal_access_token_package_01>@gitlab.example.com/api/v4/projects/<project_id_package_01>/packages/pypi/simple \

但分开安装两个包却能正常完成：

pip install <package_name_01> --index-url https://<personal_access_token_name_package_01>:<personal_access_token_package_01>@gitlab.example.com/api/v4/projects/<project_id_package_01>/packages/pypi/simple
pip install <package_name_02> --index-url https://<personal_access_token_name_package_02>:<personal_access_token_package_02>@gitlab.example.com/api/v4/projects/<project_id_package_02>/packages/pypi/simple

有人知道问题出在哪里吗？
