安装tradingwithpython包时Anaconda conda安装错误

Question

在我的windows 7机器上安装anaconda之后，我尝试使用以下方法安装tradingwithpython包。

pip安装tradingwithpython

这是成功的，但当我尝试从ipython导入时，我得到了以下错误：

#==================================================
Python 2.7.6 |Anaconda 1.9.2 (32-bit)| (default, Nov 11 2013, 10:50:31) [MSC v.1500 32 bit (Intel)]

In [1]: import tradingwithpytohn

<ipython-input-1-b118a20534e9> in <module>()
----> 1 import tradingwithpytohn

ImportError: No module named tradingwithpytohn

#==========================================================

所以在这之后，我试着创建一个食谱

C:\Users\dave\Anaconda>conda skeleton pypi tradingwithpython --no-download
tradingwithpython not found, trying Tradingwithpython
Using url https://pypi.python.org/packages/source/t/tradingWithPython/tradingWithPython-0.0.10.zip (20684) for tradingWithPython.
Using "BSD" for the license
Writing recipe for tradingwithpython
Done

然后构建这个包，它给了我一个错误：

C:\Users\dave\Anaconda>conda build tradingwithpython

知道为什么这不管用吗？

谢谢。

Answer 1

ImportError:没有一个模块名为scipy

可能是您的Anaconda安装没有完成。Scipy是一个标准模块，在Anaconda安装后应该是可导入的。

你的问题似乎是一个罕见的问题，我没有听说过安装Win 7和Anaconda下的问题。

我建议你重新安装你的蟒蛇，然后再试一次。

Answer 2

把这个命令写在笔记本上，而不是终端上。

!pip install tradingWithPython

然后自动选择所需的anaconda环境。
