Question

尝试在ubuntu中安装PyV8时，输入命令：

python setup.py build

然后显示此错误：

error: command 'c++' failed with exit status 1

有人对此有解决方案吗？

这是我在Dockerfile中的内容。以下内容经过测试，在Debian Stretch上运行。我建议使用我正在使用的PyV8 / V8设置 - 我花了至少一个星期的时间来确定哪种组合不会导致内存泄漏。我还建议阅读讨论和JSContext修复here和here。

简而言之，对PyV8的支持几乎不存在 - 或者你只是将它用作玩具，或者你完全遵循这个配方，或者你花费了大量的时间和精力来分配回购并使其更好。如果重新开始，我建议使用Node-JS，并通过一些IPC方法与Python进行通信。

旧版本取决于现已解散的googlecode并且是为Ubuntu 12.04制作的：

export MY_LIB_FOLDER=[PUT-YOUR-DESIRED-INSTALL-PATH-HERE]

apt-get install -y libboost-thread-dev
apt-get install -y libboost-all-dev
apt-get install -y libboost-dev
apt-get install -y libboost-python-dev
apt-get install -y git-core autoconf libtool systemtap
apt-get install -y subversion

apt-get install -y wget
mkdir -p $MY_LIB_FOLDER/boost && cd $MY_LIB_FOLDER/boost && wget http://sourceforge.net/projects/boost/files/boost/1.54.0/boost_1_54_0.tar.gz && tar -xvzf boost_1_54_0.tar.gz
cd $MY_LIB_FOLDER/boost/boost_1_54_0 && ./bootstrap.sh && ./b2 install --prefix=/usr/local --with-python --with-thread && ldconfig && ldconfig /usr/local/lib

有同样的问题，这对我有用：

export LIB=~
apt-get install -y curl libboost-thread-dev libboost-all-dev libboost-dev libboost-python-dev git-core autoconf libtool
svn checkout -r19632 http://v8.googlecode.com/svn/trunk/ $LIB/v8
export V8_HOME=$LIB/v8
svn checkout http://pyv8.googlecode.com/svn/trunk/ $LIB/pyv8 && cd $LIB/pyv8 && python setup.py build && python setup.py install

我正在使用基于Debian的发行版。以下是我安装PyV8的方法（你需要这样做安装了git）：

cd / usr / share

sudo git clone https://github.com/emmetio/pyv8-binaries.git

cd pyv8-binaries /

sudo unzip pyv8-linux64.zip

sudo cp -a PyV8.py _PyV8.so / usr / bin

在ubuntu上从源安装pyV8时出错
