您好,我无法在laravel homestead(vagrant)上安装v8js

看完这两个tuts

1. Install v8js on Linux (works with Homestead)！

2. Installing PHPv8js on Ubuntu！

我启动了以下命令

$sudo apt-get install libv8-dev libv8-dbg g++ cpp
$sudo pecl install v8js-0.1.3

还请注意,当我要求输入libv8的安装前缀时,我输入了/ opt / v8

编辑：按照用户的要求,我发布错误代码并删除相同的屏幕截图

这是我的错误代码

当我运行第一个命令时出现此错误

$sudo apt-get install libv8-dev libv8-dbg g++ cpp
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package libv8-dbg is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'libv8-dbg' has no installation candidate

当我运行2nd命令时,它要求我提供libv8的安装前缀…我键入/ opt / v8并得到以下错误

$sudo pecl install v8js-0.1.3

解决方法:

我已经找到了解决办法；我们应该签出5.1.99版本,因为最新的v8js版本似乎已损坏.

背景历史

stacie已将bug提升给v8团队

在构建V8#238时找不到错误“ unicode / uchar.h”,该错误也在Github上打开

tiemevanveen提供了solution log

当前解决方案

命令如下：

如果尚未安装,则安装build-essential：

sudo apt-get install build-essential

如果尚未安装libicu-dev,请执行以下操作：

sudo apt-get install libicu-dev
cd /tmp

首先安装depot_tools(需要源签出)

git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
export PATH=`pwd`/depot_tools:"$PATH"

下载v8

fetch v8
cd v8

结帐工作版本：

git checkout 5.1.99
gclient sync

使用操作系统的libicu

export GYP_DEFINES="use_system_icu=1"

构建(带有内部快照)

export GYPFLAGS="-Dv8_use_external_startup_data=0"

强制gyp使用系统范围的ld.gold

export GYPFLAGS="${GYPFLAGS} -Dlinux_use_bundled_gold=0"
make native library=shared snapshot=on -j8

安装到/ usr

sudo mkdir -p /usr/lib /usr/include
sudo cp out/native/lib.target/lib*.so /usr/lib/
sudo cp -R include/* /usr/include

…与V8相同5.2.51,libv8_libplatform.a构建在tools / gyp目录中

echo -e "create /usr/lib/libv8_libplatform.a\naddlib out/native/obj.target/tools/gyp/libv8_libplatform.a\nsave\nend" | sudo ar -M

编译php-v8js本身

cd /tmp
git clone https://github.com/phpv8/v8js.git
cd v8js
phpize
./configure
make
make test
sudo make install

然后将extension = v8js.so添加到您的php.ini文件中.
