我试图用这个 Dockerfile 安装 V8JS

FROM php:7.3-cli-buster

RUN apt-get update -y --fix-missing && apt-get upgrade -y;

# Install v8js
RUN apt-get install -y libv8-dev
RUN pecl install v8js
RUN docker-php-ext-enable v8js

但我遇到了配置错误:

检查默认路径中的 V8 文件...未找到

配置:错误:请重新安装 v8 发行版错误:`/tmp/pear/temp/v8js/configure --with-php-config=/usr/local/bin/php-config --with-v8js' failed 命令' /bin/sh -c pecl install v8js' 返回一个非零代码:1

如何解决配置错误(我猜是因为缺少 V8 文件的路径)并在 PHP Docker FROM Debian Buster 上安装 V8JS?

来自@saulotoledo 答案的 Dockerfile 有效 :)

构建映像大约需要 60-90 分钟,映像大小为 5.47GB,基础映像 (FROM) 为 7.3-cli-buster 367MB

使用 V8JS 构建 Dockerfile php 从@saulotoledo 答案复制代码并将其粘贴到名为的文件中Dockerfile

然后在同一目录中运行此命令:

docker build --tag "test-php-js" .

然后以这种方式运行容器:

docker run -it --rm --entrypoint="" --name="php-v8js" test-php-js /bin/sh

您应该登录到 php-cli 的终端,输入:

php -m

你应该会看到一个启用的扩展列表,包括v8js

类型:

php --ri v8js

查看一些详细信息,例如:

V8 Javascript Engine => enabled
V8 Engine Compiled Version => 7.4.288.21
V8 Engine Linked Version => 7.4.288.21
Version => 2.1.1

现在是你们一直在等待的樱桃部分 - 输入:

php -r "(new V8Js())->executeString(\"print('Hello' + ' from JS ' + 'World!')\", 'basic.js');";

查看支持 V8JS 的 php 运行 js 代码:D

Hello from JS World!

请注意,我需要在命令\的每个 JS 双引号前添加额外的反斜杠。但这只是由于在 cli 模式下从 php 作为 oneliner 运行 JS。"php -r

通常你不需要 查看官方 PHP 文档示例

有谁知道是否可以安装和启用 V8JS 扩展而不从其源代码构建它,而是像我一开始尝试的那样使用 Debian Buster 包和 PECL?

编辑: 那应该可以解决您的问题(请注意,我正在手动编译它):

FROM php:7.3-cli-buster
ENV V8_VERSION=7.4.288.21

RUN apt-get update -y --fix-missing && apt-get upgrade -y;

# Install v8js (see https://github.com/phpv8/v8js/blob/php7/README.Linux.md)
RUN apt-get install -y --no-install-recommends \
    libtinfo5 libtinfo-dev \
    build-essential \
    curl \
    git \
    libglib2.0-dev \
    libxml2 \
    python \
    patchelf \
    && cd /tmp \
    \
    && git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git --progress --verbose \
    && export PATH="$PATH:/tmp/depot_tools" \
    \
    && fetch v8 \
    && cd v8 \
    && git checkout $V8_VERSION \
    && gclient sync \
    \
    && tools/dev/v8gen.py -vv x64.release -- is_component_build=true use_custom_libcxx=false

RUN export PATH="$PATH:/tmp/depot_tools" \
    && cd /tmp/v8 \
    && ninja -C out.gn/x64.release/ \
    && mkdir -p /opt/v8/lib && mkdir -p /opt/v8/include \

    && apt-get install patchelf \
    && for A in /opt/v8/lib/*.so; do patchelf --set-rpath '$ORIGIN' $A;done

# Install php-v8js
RUN cd /tmp \
    && git clone https://github.com/phpv8/v8js.git \
    && cd v8js \
    && phpize \
    && ./configure --with-v8js=/opt/v8 LDFLAGS="-lstdc++" \
    && make \
    && make test \
    && make install

RUN docker-php-ext-enable v8js

老答案:

我相信你需要手动编译V8。我还不确定为什么libv8-dev还不够。由于这不起作用,因此您需要编译它,因为它是必需的

也就是说,此链接可能会有所帮助。但是这里给出了官方的编译说明。经过几次测试后,我注意到您需要在libtinfo5libtinfo-devapt-get install.

在 Dockerfile 中使用该编译指令后,V8 将正确编译。之后,您在安装 pecl 时仍然会遇到一些问题。不幸的是,我现在不得不停止调查这个问题,编译需要一些时间。但是,以下链接可能会帮助您解决问题:

  • 如果您仍然无法使用 ninja 进行编译,请使用此工具
  • 这个提供了另一个用于编译 V8 的 Dockerfile,但是基础镜像不同,需要一些调整。

我希望它有所帮助。如果您设法拥有一个工作的 Dockerfile,请稍后与我们分享。如果我稍后有时间进行调查并且取得了一些进展,我将编辑我的答案。

感谢 saulotoledo,我创建了需要 950MB 和 398MB 基本图像的示例图像(php:7.3-cli-buster)

它也适用于 PHP FPM, 如果你想要 FPM 版本FROM php:7.3-cli-buster,只需更改。FROM php:7.3-fpm-buster

Dockerfile

FROM php:7.3-cli-buster
ENV V8_VERSION=7.4.288.21
# php:7.3-cli-buster 398MB

RUN apt-get update -y --fix-missing && apt-get upgrade -y;

# Install required CLI tools
RUN apt-get install -y --no-install-recommends \
    libtinfo5 libtinfo-dev \
    build-essential \
    curl \
    git \
    libglib2.0-dev \
