我尝试使用此 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
但我遇到配置错误:
checking for V8 files in default path... not found
configure: error: Please reinstall the v8 distribution ERROR: `/tmp/pear/temp/v8js/configure --with-php-config=/usr/local/bin/php-config --with-v8js' failed The command '/bin/sh -c pecl install v8js' returned a non-zero code: 1
完整的 cli 输出:

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 上从 Debian Buster 安装 V8JS？
编辑
@saulotoledo 的 Dockerfile 答案有效:)
构建镜像大约需要 60-90 分钟，镜像大小为 5.47GB，而基础镜像 (FROM) 7.3-cli-buster 为 367MB
要使用 V8JS 构建 Dockerfile php，请复制 @saulotoledo 答案中的代码并将其粘贴到名为 Dockerfile 的文件中
然后在同一目录中运行以下命令:
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
您应该会看到已启用的扩展列表，其中包括 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 php 在 V8JS 支持下运行 js 代码:D
Hello from JS World!
请注意，我需要在 php -r 命令的每个 JS 双引号 " 前面添加额外的反斜杠 \。但这仅是由于在 cli 模式下从 php 作为 oneliner 运行 JS。
通常情况下你不需要这个 See an official PHP documentation example
有谁知道是否可以安装并启用 V8JS 扩展，而无需从源代码构建它，而是使用 Debian Buster 包和 PECL，就像我一开始尝试的那样？
最佳答案
编辑: 这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)

# Install php-v8js
RUN cd /tmp \

RUN docker-php-ext-enable v8js
旧答案:
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，您需要编译它，因为 it is a requirement .
也就是说，this link可能会有帮助。但官方给出了编译说明here 。经过几次测试后，我注意到您需要将 libtinfo5 添加到您的 apt -get install，否则说明中的ninja构建会失败。
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:
希望对您有帮助。如果您设法拥有一个可用的 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。
