Question

我最近安装了Python 2.7.11并安装了一些软件包。我虽然numpy安装了pip并试图安装scipy，但在运行sudo pip install scipy时，它给了我以下错误。

所以，我继续通过sudo apt-get install python-scipy安装它，它运行没有问题。但是，当我进入python解释器并尝试导入scipy时，它表示该模块不存在。我哪里做错了？我也尝试了以下代码。

for p in sys.path:
    if os.path.exists(os.path.join(p, 'numpy')):
        print p
        break
else:
    print "Numpy does not exist"

导致＆＃34; /usr/local/lib/python2.7/site-packages＆＃34;。为scipy运行相同的代码说＆＃34; Scipy不存在＆＃34;。我认为这可能是一个路径问题。任何帮助将不胜感激。

Answer 1

在Ubuntu中，与apt-get install一起安装的Python 2.7软件包放在文件夹/usr/lib/python2.7/dist-packages中。因此，您需要更新Python路径。

export PYTHONPATH="/usr/lib/python2.7/dist-packages:/usr/local/lib/python2.7/site-packages"

此外，您的pip install scipy失败了，因为您没有安装scipy所依赖的库/包。

Answer 2

我缺少的是scipy的依赖。缺少的库是libatlas-base-dev。安装完毕后，安装scipy没有任何问题。

感谢大家节省时间。特别提到@ knh170的有用评论。我找到了答案。

虽然已安装但无法导入scipy
