Question

"cd client && npm install --only=dev && npm install && npm run build"

--only=dev在package.json中是什么意思。
缺少它如何影响代码？

这可以控制是否安装开发或生产依赖项（而不是两者），如here所示：

static const MemMapEntry base_memmap[] = {
    /* Space up to 0x8000000 is reserved for a boot ROM */
    [VIRT_FLASH] =              {          0, 0x08000000 },
    [VIRT_CPUPERIPHS] =         { 0x08000000, 0x00020000 },
    /* GIC distributor and CPU interfaces sit inside the CPU peripheral space */
    [VIRT_GIC_DIST] =           { 0x08000000, 0x00010000 },
    [VIRT_GIC_CPU] =            { 0x08010000, 0x00010000 },
    [VIRT_GIC_V2M] =            { 0x08020000, 0x00001000 },
    [VIRT_GIC_HYP] =            { 0x08030000, 0x00010000 },
    [VIRT_GIC_VCPU] =           { 0x08040000, 0x00010000 },
    /* The space in between here is reserved for GICv3 CPU/vCPU/HYP */
    [VIRT_GIC_ITS] =            { 0x08080000, 0x00020000 },
    /* This redistributor space allows up to 2*64kB*123 CPUs */
    [VIRT_GIC_REDIST] =         { 0x080A0000, 0x00F60000 },
    [VIRT_UART] =               { 0x09000000, 0x00001000 },
    [VIRT_RTC] =                { 0x09010000, 0x00001000 },
    [VIRT_FW_CFG] =             { 0x09020000, 0x00000018 },
    [VIRT_GPIO] =               { 0x09030000, 0x00001000 },
    [VIRT_SECURE_UART] =        { 0x09040000, 0x00001000 },
    [VIRT_SMMU] =               { 0x09050000, 0x00020000 },
    [VIRT_PCDIMM_ACPI] =        { 0x09070000, MEMORY_HOTPLUG_IO_LEN },
    [VIRT_ACPI_GED] =           { 0x09080000, ACPI_GED_EVT_SEL_LEN },
    [VIRT_NVDIMM_ACPI] =        { 0x09090000, NVDIMM_ACPI_IO_LEN},
    [VIRT_MMIO] =               { 0x0a000000, 0x00000200 },
    /* ...repeating for a total of NUM_VIRTIO_TRANSPORTS, each of that size */
    [VIRT_PLATFORM_BUS] =       { 0x0c000000, 0x02000000 },
    [VIRT_SECURE_MEM] =         { 0x0e000000, 0x01000000 },
    [VIRT_PCIE_MMIO] =          { 0x10000000, 0x2eff0000 },
    [VIRT_PCIE_PIO] =           { 0x3eff0000, 0x00010000 },
    [VIRT_PCIE_ECAM] =          { 0x3f000000, 0x01000000 },
    /* Actual RAM size depends on initial RAM and device memory settings */
    [VIRT_MEM] =                { GiB, LEGACY_RAMLIMIT_BYTES },
};

package.json中的--only = dev是什么意思？
