This is because when you launch vuepress build, it will overwrite the temporary files (vuepress/lib/app/.temp) generated by vuepress dev. for now we don't plan to change temp directory by checking if a vuepress process already exists. but in the next version, you will have the chance to change temp manually:

    "dev": "vuepress dev docs --temp .temp1",
    "build": "vuepress build docs --temp .temp2"
