尝试在 ubuntu 中安装 PyV8 时，输入以下命令：

python setup.py build

然后它显示此错误：

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

有人对此有解决方案吗？

这是我的 Dockerfile 中的内容。以下内容在 Debian Stretch 上经过测试并在生产环境中运行。我建议完全使用我正在使用的 PyV8 / V8 设置——我至少花了一周时间来弄清楚哪种组合不会导致内存泄漏。我还建议通读此处和此处的讨论和 JSContext 修复。

简而言之，对 PyV8 的支持几乎是不存在的——要么你把它当作一个玩具来使用，要么你完全按照这个配方，或者你花费大量的时间和精力来分叉 repo 并使其变得更好。如果从头开始，我建议改用 Node-JS，并通过一些 IPC 方法与 Python 进行通信。

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。这是我安装 PyV8 的方法（你需要安装 git）：

cd /usr/share

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

cd pyv8-二进制文件/

sudo 解压 pyv8-linux64.zip

sudo cp -a PyV​​8.py _PyV8.so /usr/bin
