在 Docker 文件上安装 yarn global

Question

我正在尝试获得由纱线和 docker 图像识别的全局 package 。

FROM ruby:2.7.2

RUN apt-get update -qq && apt-get install -y nodejs libvips-tools yarn

# Install all gems first.
# This hits the warm cache if unchanged so bundling is faster.
COPY Gemfile* /tmp/
WORKDIR /tmp
RUN bundle install

WORKDIR /sapco
COPY . /sapco

# Get yarn and install global required packages
RUN yarn global add mjml

EXPOSE 3000

# Start the main process.
CMD ["rails", "server", "-b", "0.0.0.0"]

我使用docker build -f Dockerfile.dev.

我收到以下错误：

Answer 1

问题是纱线与cmdtest提供的另一个二进制文件的名称相同

我最终将其追溯到https://github.com/yarnpkg/yarn/issues/2821并使用此命令解决了我的问题以在 Dockerfile 中运行。

apt remove -y cmdtest
apt remove -y yarn
curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add -
echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list
apt update
apt install yarn
