Question

WARNING in ./node_modules/React/cjs/react.development.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:

• /Users/eddie/Desktop/mofang_project/mofang_crm/node_modules/React/cjs/react.development.js
  Used by 1 module(s), i. e.
  /Users/eddie/Desktop/mofang_project/mofang_crm/node_modules/React/index.js

warning如上，相似的文件名我也都修改了，但还是这个样子

Answer 1

是不是文件名大小写的问题, There are multiple modules with names that only differ in casing.
