Python Can'；t在生产服务器上安装SciPy

我正试图在云中的Ubuntu机器上安装SciPy。以下是我遵循的步骤：

• sudopip安装numpy
• sudo-apt-get-install-gfortran
• sudo apt get安装libblas dev
• sudo apt get安装liblapack dev
• sudo-apt-get-install-g++
• sudopip安装scipy

请参考Ubuntu 14.04和Python 2.7.6。我没有安装Python，它已经在机器中了，就像pip和easy_install一样。以下是pip.log：

pip文件：

#!/opt/bitnami/python/bin/.python2.7.bin
# EASY-INSTALL-ENTRY-SCRIPT: 'pip==1.5.6','console_scripts','pip'
__requires__ = 'pip==1.5.6' import sys from pkg_resources import load_entry_point

if __name__ == '__main__':
    sys.exit(
        load_entry_point('pip==1.5.6', 'console_scripts', 'pip')()
    )

简易安装文件：

#!/usr/bin/env /opt/bitnami/python/bin/python
# EASY-INSTALL-ENTRY-SCRIPT: 'distribute==0.6.34','console_scripts','easy_install'
__requires__ = 'distribute==0.6.34' import sys from pkg_resources import load_entry_point

if __name__ == '__main__':
    sys.exit(
        load_entry_point('distribute==0.6.34', 'console_scripts', 'easy_install')()
    )

请帮忙

这是由gfortran编译器标志引起的吗？只是怀疑而已。

Ubuntu软件包 SciPy手册：

皮普 另一种办法是：

我刚刚在AWS Ubuntu14.04机器上测试了它，经过一个很长的编译过程和大量的警告，一切似乎都正常

---

我通常建议使用后者，因为它适用于任何virtualenv，而前者在系统范围内安装软件包。

这个问题仍然存在，因此我删除了

/opt/bitnami/python

上的自定义安装，并开始使用系统安装，现在一切正常

我使用安装了scipy和numpy

sudo apt-get install python-numpy python-scipy

---

通过更改以下环境变量，我可以在bitnami上安装numpy/scipy：

export LDFLAGS="-shared"

然后，安装到scipy的步骤如下：

sudo apt-get update -y
sudo apt-get install python-pip python-dev build-essential
sudo pip install numpy
sudo apt-get install libatlas-base-dev gfortran
sudo pip install scipy

---

我确实通过apt get安装了它们，但python表现得好像没有安装：没有名为SCIPY的模块。它们可能安装在不同的python解释器上。尝试pip方式，这也将在virtualenv中工作。我如您所述做了，但同样的错误再次显示：（，我不确定，但我认为这与gfortran编译器标志有关

export LDFLAGS="-shared"

sudo apt-get update -y
sudo apt-get install python-pip python-dev build-essential
sudo pip install numpy
sudo apt-get install libatlas-base-dev gfortran
sudo pip install scipy
