【问题描述】：
我安装了yarn，然后我想使用下一个 Dockerfile 执行它：
FROM ubuntu:trusty
....
USER node
RUN npm install -g yarn
RUN ["/bin/bash", "-c","yarn install"]
但它失败了：
/bin/bash: yarn: command not found
ERROR: Service 'falink-frontend4' failed to build: The command '/bin/bash -c yarn install' returned a non-zero code: 127
我只是尝试使用下一个：
FROM ubuntu:trusty
....
USER node
RUN npm install -g yarn
RUN yarn install
但它失败了：
/bin/sh: 1: yarn: not found
ERROR: Service 'falink-frontend4' failed to build: The command '/bin/sh -c yarn install' returned a non-zero code: 127
然后我使用docker exec -it XXXXX /bin/bash 连接到容器，运行yarn install，它工作正常。当我在 docker 容器中访问时，我使用 node 用户，就像在 Dockerfile 上一样。
这是我输入的 Dockerfile：
FROM ubuntu:trusty
# Create app directory
RUN mkdir -p /usr/src/app
#use mirrors for faster apt downloads no matter where the machine that builds the image is
RUN echo "deb mirror://mirrors.ubuntu.com/mirrors.txt trusty main restricted universe multiverse" > /etc/apt/sources.list; \
echo "deb mirror://mirrors.ubuntu.com/mirrors.txt trusty-updates main restricted universe multiverse" >> /etc/apt/sources.list; \
echo "deb mirror://mirrors.ubuntu.com/mirrors.txt trusty-backports main restricted universe multiverse" >> /etc/apt/sources.list; \
echo "deb mirror://mirrors.ubuntu.com/mirrors.txt trusty-security main restricted universe multiverse" >> /etc/apt/sources.list

可能是什么问题？
