docker bash：npm：构建容器后找不到命令

Question

我正在使用以下 Dockerfile 构建映像。

但是在构建之后，当我运行 npm install 时，它会显示 bash: npm: command not found

我有2个RUN命令构建2层，第一个基本上是为镜像构建Python环境，包括安装pyodbc驱动和安装必要的包。

第二层是安装node。

dockerfile 哪一步出错了？

Debian Nodejs 可能是虚假的。使用nodejs官方说明https://github.com/nodesource/distributions/blob/master/README.md#debinstall安装nodejs。
