Docker/Node-red - 如果卷在 USB 闪存驱动器上，则 npm 无法安装调色板

Question

如果容器卷位于闪存驱动器上，我无法在 Node-red 中安装新的调色板，因为 npm 没有正确的访问权限。你能帮帮我吗？

# docker-compose.yml

  node-red:
    container_name: node-red
    image: nodered/node-red:latest
    restart: unless-stopped
    environment:
     - TZ=Europe/Rome
    network_mode: "host"
    ports:
     - "1880:1880"
    volumes:
     - /media/data/node-red:/data  <---- MY USB FLASH DRIVE (FAT32 - vfat)
#    - /home/pi/data/node-red:/data.  <<-- default place 
    user: 1000:1000
    depends_on:
#     - homeassistant
     - mosquitto

OS 是 pi4 上的 raspian lite，USB 驱动器在启动时挂载，选项为：

# /etc/fstab

PARTUUID=af3416fc-01  /media/data vfat    auto,rw,user,users,exec,noatime,uid=1000,gui=1000,umask=000  0  0

这是日志文件

编辑：添加完整的 /etc/fstab 行和从网络浏览器获取的 npm 安装日志

提前致谢

Answer 1

它不起作用，因为 USB 记忆棒上的胖文件系统不支持符号链接，而 npm 正试图将其用作安装节点的一部分。

您最好的选择是重新格式化 U 盘以使用 ext2（或类似）作为文件系统。
