/bin/sh: npm: 命令未找到

Question

我正在為 stf.installing nodejs 創建一個 docker 鏡像，直接使用 apt-get install nodejs，有很多問題。所以我決定采用 nvm 方式。但是安裝后 RUN npm install 失敗我正在使用 su 用戶名 docker build 構建 docker 鏡像..

make sure apt is up to date
RUN apt-get update --fix-missing
RUN apt-get install -y curl
RUN sudo apt-get install -y build-essential libssl-dev
ENV NVM_DIR /usr/local/nvm
ENV NODE_VERSION 6

# Install nvm with node and npm
RUN curl https://raw.githubusercontent.com/creationix/nvm/v0.30.1/install.sh | bash \
    && source $NVM_DIR/nvm.sh \
    && nvm install $NODE_VERSION \
    && nvm alias default $NODE_VERSION \
    && nvm use default

ENV NODE_PATH $NVM_DIR/v$NODE_VERSION/lib/node_modules
ENV PATH      $NVM_DIR/versions/node/v$NODE_VERSION/bin:$PATH

#WORKDIR /usr/app


# Install app dependencies
RUN npm install

和輸出

=> Downloading nvm from git to '/usr/local/nvm'
=> Cloning into '/usr/local/nvm'...
* (HEAD detached at v0.30.1)
  master

=> Appending source string to /root/.bashrc
=> Close and reopen your terminal to start using nvm

您$NODE_VERSION變量值6中的定義， Dockerfile （ ENV NODE_VERSION 6 ），但它應該是6.13.0 ，使下面的線可以正常工作：

ENV PATH      $NVM_DIR/versions/node/v$NODE_VERSION/bin:$PATH

（映射到/usr/local/nvm/versions/node/v6.13.0/bin ）

否則，您實際上是在生成以下（錯誤的）路徑：

/usr/local/nvm/versions/node/v6/bin
