google-api-python-client 不起作用并使 Spyder 在启动时失败

Question

我在我的 Ubuntu 13.04 上安装了 google-api-python-client

sudo easy_install --upgrade google-api-python-client

正如人们所说的here。

之后我尝试用它在 python 中翻译一些东西。我从here获取代码。

>>> from apiclient.discovery import build
>>> service = build('translate', 'v2', developerKey='MyApiKey')
Traceback (most recent call last):

怎么了？

其实我一开始是想在 Spyder 中做的，但是启动失败：

不知何故，google_api_python_client 干扰了它的启动。 WTF 与 google API 绑定到 python 有问题吗？还是和我一起？

请帮忙。

根据您在尝试启动 Spyder 时收到的回溯，看起来 Google API Python 客户端未能以正确的权限安装。更准确地说，Spyder 正在尝试从 IPython 加载组件，这些组件利用 Pygments 语法高亮显示。 Pygments 正在尝试使用pkg_resources 模块自动发现包，但由于权限问题，它无法读取google_api_python_client egg。我怀疑如果您尝试以 root 身份运行 Spyder，它可能会正常启动。

显然，此问题有多种潜在来源。这可能是因为谷歌包根本没有正确构建，如here 所述，或者可能是您有另一个版本的setuptools 在某处徘徊，如here 所述。您可以尝试删除google_api_python_client 并通过pip 重新安装。在任何情况下，删除google_api_python_client 应该可以让 Spyder 再次正常启动。
