Question

我试图在python 2.7上获取atpy。我从

下载了ATpy0.9.6

https://pypi.python.org/pypi/ATpy/0.9.6

然后tar，然后运行：

cd ATpy0.9.6 sudo python setup.py install

事情似乎运作良好。

但是当我尝试在python上导入atpy时，我总是收到此错误消息：

ImportError：没有名为astropy.io的模块

更准确地说，

>>> import atpy
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/atpy/__init__.py", line 1, in <module>
    from .basetable import Table, TableSet, VectorException
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/atpy/basetable.py", line 15, in <module>
    from . import registry
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/atpy/registry.py", line 164, in <module>
    from . import fitstable
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/atpy/fitstable.py", line 8, in <module>
    from astropy.io import fits
ImportError: No module named astropy.io
>>>

有人能帮我解决问题吗？

Answer 1

也许'atpy'包依赖于另一个名为'astropy.io'的包你不知道？是的，这是https://astropy.readthedocs.org/en/v0.1/index.html

从pypi.python.org下载tar球是安装Python包的错误方法。正确的方法（尽管Python文档解释得很差）是运行像

这样的命令

pip install atpy

此命令将安装您的软件包及其所有依赖项。

如果缺少命令pip，则必须安装它，具有讽刺意义的确非常复杂。

Answer 2

在我的情况下，解决方案是安装astropy

pip install --no-deps astropy

ATpy ImportError：没有名为astropy.io的模块
