运行 vue 项目时,警告”多个模块的名称只是大小写不同“

 warning  in ./node_modules/Vant/es/utils/validate/number.js

There are multiple modules with names that only differ in casing.
This can lead to unexpected behavior when compiling on a filesystem with other case-semantic.
Use equal casing. Compare these module identifiers:
* D:SYGT_Meyzcmu_appointment
ode_modulesVantesutilsvalidate
umber.js
    Used by 5 module(s), i. e.
    D:SYGT_Meyzcmu_appointment
ode_modulesVantesdatetime-pickerutils.js
* D:SYGT_Meyzcmu_appointment
ode_modulesvantesutilsvalidate
umber.js
    Used by 5 module(s), i. e.
    D:SYGT_Meyzcmu_appointment
ode_modulesvantesstepperindex.js

 warning  in ./node_modules/Vant/es/utils/validate/system.js

There are multiple modules with names that only differ in casing.

ode_modulesVantesaddress-editDetail.js

    Used by 2 module(s), i. e.
    D:SYGT_Meyzcmu_appointment

 warning  in ./node_modules/Vant/es/utils/vnodes.js

There are multiple modules with names that only differ in casing.
This can lead to unexpected behavior when compiling on a filesystem with other case-semantic.
Use equal casing. Compare these module identifiers:
* D:SYGT_Meyzcmu_appointment
ode_modulesVantesutilsvnodes.js
    Used by 2 module(s), i. e.
    D:SYGT_Meyzcmu_appointment
ode_modulesVantesmixins
elation.js

ode_modulesvantesutilsvnodes.js
    Used by 2 module(s), i. e.
    D:SYGT_Meyzcmu_appointment

elation.js

警告代码是这样的,换了一个电脑,重新安装环境然后运行就出现这种警告了

记录,npm 中运行项目,警告:There are multiple modules with names that only differ in casing.

Use equal casing. Compare these module identifiers:
***
**其中报错的功能模块为 node_modules 下引入的 node 包**
***
* D:SYGT_Meyzcmu_appointment**node_modules**Vantesutilsvalidatesystem.js
    Used by 2 module(s), i. e.
    D:SYGT_Meyzcmu_appointment**node_modules**Vantesaddress-editDetail.js
* D:SYGT_Meyzcmu_appointment**node_modules**vantesutilsvalidatesystem.js
    Used by 2 module(s), i. e.
    D:SYGT_Meyzcmu_appointment**node_modules**vantesaddress-editDetail.js
提示为 node_modules 中的包大小写不一致,考虑到昨天更换电脑设备,因此怀疑问题出现在安装环境中,删除了 node_modules 使用 cnpm iinstall 重新安装,然后就没有报错了
**总结:**
    如果项目中初始安装依赖包时使用的时 cnpm 那么之后的项目统一使用 cnpm 安装依赖项,如果使用 npm 或 taobao 镜像安装可能会出现莫名其妙的报错
