如何在PHP5.5上安装V8js? [英] How to install V8js on PHP5.5?

问题描述

我想在Ubuntu 12.04上安装PHP5.5的v8js扩展，但无法使其正常工作.

当我尝试使用PECL安装v8js扩展版本0.2.0(最新)时，出现以下消息:

配置:错误:libv8必须为3.24.6或更高版本 错误:`/tmp/pear/temp/v8js/configure --with-v8js'失败

如果我尝试安装旧版本，则出现编译错误.此消息与我的问题非常相似:在ubuntu上为php安装v8js

如何解决此问题?

即使将PHPbrew降级到PHP 5.4，我也无法在使用PHP5.5的Ubuntu 14.04上安装它.但是，将Ubuntu 12.04与PHP 5.4结合使用非常有效.我没有尝试在Ubuntu 12.04上从PHP 5.5降级到5.4.

解决方案

如果找不到libv8-dev或libv8-dbg，则可以通过运行命令找到正确的版本

~$ apt-cache search libv8
libv8-3.14-dbg - V8 JavaScript engine - debugging symbols
libv8-3.14-dev - V8 JavaScript engine - development files for 3.14 branch
libv8-3.14.5 - V8 JavaScript engine - runtime library
libv8-dev - V8 JavaScript engine - development files for latest branch

然后您可以运行

~$ sudo apt-get install libv8-3.14-dev libv8-3.14-dbg g++ cpp

然后您可以尝试通过运行pecl安装v8js

~$ sudo pecl install v8js-0.2.0

如果该命令返回这样的错误

configure: error: libv8 must be version 3.24.6 or greater
ERROR: `/tmp/pear/temp/v8js/configure --with-v8js' failed

您可以尝试运行

~$ sudo pecl install v8js-0.2.0

来安装v8js-0.1.3

~$ sudo pecl install v8js-0.1.3

然后编辑您的php.ini以添加v8js扩展名

~$ echo "extension=v8js.so" >> /etc/php5/cli/php.ini

I want to install the v8js extension for PHP5.5 on Ubuntu 12.04 but can't make it working.

When I try to install the v8js extension version 0.2.0 (latest) with PECL, I have this message:

configure: error: libv8 must be version 3.24.6 or greater ERROR: `/tmp/pear/temp/v8js/configure --with-v8js' failed

If I try to install an old version, I have a compilation error. This message is very similar to my issue: Install v8js for php on ubuntu

How can I fix this issue?

EDIT: I couldn't install it on Ubuntu 14.04 with PHP5.5, even with a PHP downgrade with PHPbrew to PHP 5.4. However, using Ubuntu 12.04 with PHP 5.4 works great. I didn't try the downgrade from PHP 5.5 to 5.4 on Ubuntu 12.04.

解决方案

in case you can't find libv8-dev or libv8-dbg, you can find the correct version by run command

~$ apt-cache search libv8
libv8-3.14-dbg - V8 JavaScript engine - debugging symbols
libv8-3.14-dev - V8 JavaScript engine - development files for 3.14 branch
libv8-3.14.5 - V8 JavaScript engine - runtime library
libv8-dev - V8 JavaScript engine - development files for latest branch

then you can run

~$ sudo apt-get install libv8-3.14-dev libv8-3.14-dbg g++ cpp

then you can try to install v8js via pecl by running

~$ sudo pecl install v8js-0.2.0

if that command return error like this

configure: error: libv8 must be version 3.24.6 or greater
ERROR: `/tmp/pear/temp/v8js/configure --with-v8js' failed

you can try to install v8js-0.1.3 instead by running

~$ sudo pecl install v8js-0.1.3

then edit your php.ini to add v8js extension

~$ echo "extension=v8js.so" >> /etc/php5/cli/php.ini
