google-使用测试平台的 nosetests 的云存储库

Question

我已将 google-cloud-storage pip 安装到 lib 目录中并出售。在我的 python appengine 应用程序开发期间，它运行在本地运行得很好。但是，当我尝试运行通过 nose 和 testbed 进行单元测试时，我得到 "The 'google-cloud-core' distribution was not found and is required by the application"。这是堆栈：

Traceback (most recent call last):

    raise DistributionNotFound(req, requirers)
DistributionNotFound: The 'google-cloud-core' distribution was not found and is required by the application

有什么想法吗？

Answer 1

我遇到了与 google-cloud-translate 相同的问题，我被迫也安装了软件包 "globally"，即 pip install google-cloud-translate。

Answer 2

在为同样的问题苦苦挣扎之后，我发现错误是因为供应商 pip 库在调用 nosetests 之前不在 PYTHONPATH 中。尝试将供应商库添加到 PYTHONPATH，然后运行测试。

    export PYTHONPATH="$(HOME)/Projects/myproject/pip_lib:$$PYTHONPATH"; \
    nosetests .
