解决 Anaconda/iPython Notebooks/Spyder IDE zmq lib import 启动失败？

Question

这是在 Windows 7 - 64、python 2.7.8 上全新安装的 Anaconda 2.1。 Spyder IDE 无法启动，并在 python spyder --reset 是运行来自 cli 时抛出相同的 error/writes 相同的回溯。查看回溯，加载 zmq 模块似乎是一个问题。该模块的 \__init__.py 查找具有以下扩展之一的任何预编译 libzmq 文件：pyd、so、dll、dylib，并添加它们列出 bundled，然后尝试加载 bundled[0]。

bundled = []
bundled_sodium = []
for ext in ('pyd', 'so', 'dll', 'dylib'):
    bundled_sodium.extend(glob.glob(os.path.join(here, 'libsodium*.%s*' % ext)))
    bundled.extend(glob.glob(os.path.join(here, 'libzmq*.%s*' % ext)))

令人困惑的是 libzmq.pyd 正好位于 Anaconda2.1\Lib\site-packages\zmq 目录中！在查看了代码和关于 SO 的其他问题之后，我被难住了。请帮助。

编辑：此问题还导致 iPython 笔记本无法打开。回溯中的相同错误：

Answer 1

您正在以某种方式在 C:\Python27 中安装 Python。您是否设置了 PYTHONPATH 环境变量？如果是这样，请取消设置。

最简单的解决方案是删除或留出 C:\Python27。
