python - 如何从多个 pypi 存储库安装 python 包？

Question

我pipenv用作包管理工具，对于我的项目，我使用来自 pypi 和其他私有本地项目的包，为此我们做了一个私有 pypi 存储库，但是在尝试安装包时，出现以下错误：

File "/usr/local/Cellar/pipenv/8.3.2_1/libexec/lib/python3.6/site-packages/pipenv/utils.py", line 382, in prepare_pip_source_args
    pip_args.extend(['-i', sources[0]['url']])
TypeError: 'NoneType' object is not subscriptable

我的 Pipfile 如下所示：

[[source]]

url = "https://pypi.python.org/simple"
verify_ssl = true
name = "pypi"

[[source]]
url = "https://my.domain.com/repository/"
verify_ssl = true
name = "local"

[packages]

flask = "*"
sqlalchemy = "*"
gunicorn = "*"
...
my_project = {version="*", index="local"}


[dev-packages]

tox = "*"
pytest = "*"
"flake8" = "*"


[requires]

python_version = "3.6"

我做错了什么？我该如何解决这个问题！？
