  This module is declared with using 'export =', and can only be used with a default import when using the 'esModuleInterop' flag.

对引用的方式进行修改

 

import md5 from "md5"   ==> import * as md5 from "md5"

 

在测试TypeScript时，使用package.json 中的script 命令时，不能使用

import md5 from "md5"

 

而在添加了tsconfig.json 

{

   "compilerOptions": {

   

    "target": "es6",                                  /* Set the JavaScript language version for emitted JavaScript and include compatible library declarations. */

   

    "module": "es6",                                /* Specify what module code is generated. */

 

    "esModuleInterop": true,                             /* Emit additional JavaScript to ease support for importing CommonJS modules. This enables 'allowSyntheticDefaultImports' for type compatibility. */

 

    "forceConsistentCasingInFileNames": true,            /* Ensure that casing is correct in imports. */

   

    "strict": true,                                      /* Enable all strict type-checking options. */

   

    "skipLibCheck": true,                                 /* Skip type checking all .d.ts files. */

 

    "outDir": "./dist"

  }

}

使用tsc进行build 时，又可以使用 import md5 from "md5"，但是不能使用 import * from as md5 from "md5"
