a4ce5fe396375ed99523c7bafbba1a9edc685068620db42eaafea4ed0c818680基于提交的镜像运行
$ docker run -it --name hexo-test -v /opt/nodejs/ -p 5000:5000 sunzy/hexo /bin/bash
root@73ae2263e4a3:/opt/nodejs# npm install -g hexo-cli
bash: npm: command not found
root@73ae2263e4a3:/# cd ~
root@73ae2263e4a3:~# pwd
/root
root@73ae2263e4a3:~# ls -a
. .. .bash_history .bashrc .profile在HOME目录下没有了nvm的目录并且无法运行npm命令……
这是为啥？docker不至于会在提交后把HOME目录初始化吧？
同样的机器上试试这个
docker run -it --name hexo-test -v /opt/nodejs/ -p 5000:5000 sunzy/hexo:v1.0 /bin/bash你commit的时候加上了v1.0的tag
