我正在尝试在ubuntu 14.04上安装llvmpy。

sudo pip安装llvmpy失败。输出的结尾是

我已经安装了llvm 3.4版本。全部输出位于http://paste.ubuntu.com/8074574/。

Answer 1

目前要求使用llvm 3.3。这是可用的，但Ubuntu14.04的默认设置(默认为更新的llvm3.4)。首先，安装llvm3.3：

sudo apt-get install llvm-3.3 llvm-3.3-runtime

然后，我们需要告诉pip使用旧的生活方式。

sudo sh -c "LLVM_CONFIG_PATH=/usr/bin/llvm-config-3.3 pip install llvmpy"

上面的内容也适用于使用python3的pip3
