Question

我尝试在基于php：7.2-apache的docker映像中安装mcrypt。因此，我使用文档中的RUN-Command并在此处回答，但收到此错误。我认为也许安装程序可能会丢失。

这是我的app.docker文件。

    FROM php:7-fpm

# Install any custom system requirements here
RUN apt-get update \
  && apt-get install -y --no-install-recommends \
    libfreetype6-dev \
    libjpeg62-turbo-dev \
    libpng-dev \
    curl \
    vim \
    cron \
    procps \
    zlib1g-dev \
    zip

RUN apt-get update && apt-get install -y libmcrypt-dev mysql-client \
    && docker-php-ext-install pdo_mysql \
    && docker-php-ext-install -j$(nproc) iconv mcrypt \
    && docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
    && docker-php-ext-install -j$(nproc) gd \
    && docker-php-ext-install zip \
    && docker-php-ext-install bcmath \
    && curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer

WORKDIR /var/www

在构建docker时报告错误。

即使在Dockerfile中指定了的路径，也显示未找到

有人知道为什么吗？

Answer 1

这是因为在php：7.1之后不推荐使用mcrypt。您可以使用仍支持mcrypt的基本映像，例如php：5.6-cli或使用mcrypt的替代方案。

Answer 2

这对我有用，复制自here：

intersect = pd.merge(df1, df2, how='inner')

如何修复Docker“ / usr / src / php / ext / mcrypt不存在”的构建错误？
