尝试安装pyamg:clang时出错：错误：没有这样的文件或目录：'“I/../boost_1_59_0”'

Question

我正在尝试在我的虚拟环境中安装pyamg。但是，我得到了以下错误。我用的是苹果操作系统。在

c++: pyamg/amg_core/amg_core_wrap.cxx

事实上，我认为@oarfish在评论中是正确的。问题似乎在于这些路径中有趣的“和{}字符，这与通常的"双引号符号不同。在

以下为我复制了错误：

~$ CPPFLAGS=“-I/Users/mas/PycharmProjects/kaggle-ndsb/boost_1_59_0” \
   LIBS=“-L/Users/mas/PycharmProjects/kaggle-ndsb/boost_1_59_0/stage/lib” \
   pip install pyamg

而使用"符号安装成功：

^{pr2}$

路径本身是无关的-编译成功，尽管这些目录实际上并不存在于我的机器上。在

Answer 2

我很确定路径开始处的-I就是把一切搞砸的原因。我敢打赌，如果您尝试将这些export语句添加回.bashrc，但是去掉了-I和{}前缀，那么原来的命令就可以开始工作了。在

也许你有这些是有原因的，我从来没见过，但删除这些前缀可能会起作用。在

Answer 3

使用Anaconda或{a2}

conda install pyamg

只需要几秒钟。在

您可以使用以下各项创建环境：

^{pr2}$

换成它：

source activate my_env

并安装pyamg：

conda install pyamg

您仍然可以使用pip安装conda找不到的包。在

生命太短暂，不能花时间在编译问题上。；）
