Linux上的Python模块错误

我在Linux Mint 16上使用python 2.7.如果我从程序启动器运行我的IDE(在Spyder和Pycharm上试过),我将面临错误(例如,从Alt F2的提示或桌面上的图标快捷方式)模块不加载,我得到以下错误

File "/usr/local/lib/python2.7/dist-packages/gurobipy/__init__.py", line 1, in 
    from .gurobipy import *
ImportError: libgurobi56.so: cannot open shared object file: No such file or directory

但是,如果我从命令行运行程序,模块正确加载,程序运行正常.我每个IDE只安装一个.两个实例的sys.path输出如下:

pycharm的sys.path输出从快捷方式运行:

/home/XXXXXX/bin/pycharm-community-3.1.3/helpers/pydev', '/usr/local/lib/python2.7/dist-packages/pip-1.5.5-py2.7.egg', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-x86_64-linux-gnu', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages/PILcompat', '/usr/lib/python2.7/dist-packages/gtk-2.0', '/home/XXXXXX/PycharmProjects/untitled8'] 

从命令行运行的pycharm的sys.path oyutput:

/home/XXXXXX/bin/pycharm-community-3.1.3/helpers/pydev', '/usr/local/lib/python2.7/dist-packages/pip-1.5.5-py2.7.egg', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-x86_64-linux-gnu', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages/PILcompat', '/usr/lib/python2.7/dist-packages/gtk-2.0', '/home/XXXXXX/PycharmProjects/untitled8']

gurobipy包位于/usr/lib/python2.7/dist-packages中

gurobi包的安装程序如下:

1)将下载解压缩到/ opt/gurobi562/linux64

2)在.bashrc中添加以下行

export GUROBI_HOME="/opt/gurobi562/linux64"

export PATH="${PATH}:${GUROBI_HOME}/bin"

export LD_LIBRARY_PATH="${GUROBI_HOME}/lib"

3)在/ opt/gurobi562/linux64运行python setup.py install这创建了/usr/local/lib/python2.7中的gurobipy文件夹

4)在.bashrc中添加以下行

export LD_LIBRARY_PATH="${LD_LIBRARY_PATH}:/usr/local/lib/python2.7/dist-   packages/gurobipy"

您没有设置gurobipy的路径.

下载然后解压缩到/opt.

cd to `/opt/gurobi562/linux64` and run `python setup.py install`

添加以下内容~/.bashrc.

   export GUROBI_HOME="/opt/gurobi562/linux64"
   export PATH="${PATH}:${GUROBI_HOME}/bin"
   export LD_LIBRARY_PATH="${LD_LIBRARY_PATH}:${GUROBI_HOME}/lib"

从bash类型 source ~/.bashrc

启动ipython shell并尝试from gurobipy import *,它应该可以正常工作,它唯一的错误就是没有许可证,如果你没有从这里下载并安装一个

要设置系统范围的访问权限,请先创建

sudo gedit /etc/ld.so.conf.d/gurobi_pi.conf

然后加

/opt/gurobi562/linux64/lib

并保存文件.

然后输入

sudo ldconfig

更新整个系统的库.您应该可以访问Pycharm中的共享库.
