在 Docker 中的 Ubuntu 上安装最新版本 Node (v20) 的说明不起作用？

Question

我只是按照说明在 Docker 中的 Ubuntu 上安装了最新版本的 Node (v20)，并将其包含在我的 Dockerfile 中：

FROM --platform=linux/amd64 ubuntu:22.04
RUN apt-get update
RUN apt-get -y install imagemagick
RUN apt-get -y install software-properties-common
RUN add-apt-repository ppa:fontforge/fontforge
RUN apt-get -y install fontforge
RUN apt-get -y install pandoc
RUN apt-get -y install texlive
RUN apt-get -y install ffmpeg
RUN apt-get -y install rar
RUN apt-get -y install inkscape
RUN apt-get -y install git
RUN apt-get -y install libreoffice
RUN apt-get upgrade
RUN apt-get -y install curl
RUN apt-get -y install gnupg
RUN curl -sL https://deb.nodesource.com/setup_20.x  | bash -
RUN apt-get -y install nodejs
RUN apt-get -y install npm
RUN npm install -g pnpm
RUN bash -c "$(wget -O - https://apt.llvm.org/llvm.sh)"

然后我运行此命令以获取 CLI 提示符：

docker exec -it mycontainer sh

我明白了：

$ node -v
v12.22.9

出了什么问题？应该说它显示 Node.js v20.x。

如果您使用的是 ubuntu 容器，则可以按照 nodejs 安装说明进行操作。你只需要添加到你的dockerfile中：

  RUN curl -sL https://deb.nodesource.com/setup_6.x | bash - \
    && apt-get install -y nodejs
