Question

我使用jspm＆amp; Rollup或SystemJS通过以下方式构建我的WebApp： jspm build myFile dist/myFile.js --minify

当我尝试使用SystemJS

加载myFile.js时

<script src="/jspm_packages/system.src.js"></script>
<script src="/jspm.config.js"></script>
<script>
  // `myFile` is mapped to npm:myFile@1.23.4
  SystemJS.import('myFile').catch(function (e) {
    console.log("Error with SystemJS.import myFile.js", e );
  });
</script>

我收到错误：myFile.js detected as register but didn't execute.

(SystemJS) http://localhost:3000/jspm_packages/npm/myFile@1.23.4/myFile.js detected as register but didn't execute. Error: 
  ...(call stack)...
Error loading http://localhost:3000/jspm_packages/npm/myFile@1.23.4/myFile.js

Answer 1

由于使用了jspm build，因此意味着result is able to stand alone。此外，未指定--format，the default is umd。

register是SystemJS的模块格式。要解决此问题，请手动设置或覆盖格式。以下是使用jspm：

的示例

// package.json
...
"jspm": {
  ...
  "overrides": {
    ...
    "npm:myFile@1.23.4": {
      "meta": {
        "myFile.js": {
          "format": "global"
        }
      }
    },
    ...
  }
}

myFile.js被检测为寄存器但未执行
