我正在使用安装了npm的windows机器。这是我的npm-debug.log文件

    public void calculate(View view) {
    EditText userInput = (EditText) findViewById(R.id.user_input);
    String numString = userInput.getText().toString();
    double num = new Double(numString).doubleValue();
    CheckBox ozCheckBox = (CheckBox)findViewById(R.id.oz);
    boolean ozInput = ozCheckBox.isChecked();
    CheckBox gCheckBox = (CheckBox)findViewById(R.id.g);
    boolean gInput = gCheckBox.isChecked();
    if(ozInput == true) {
        double output = num*28.3495;
    } else {
        double output = num;
    }
    TextView textView = (TextView)findViewById( R.id.output_textview );
    textView.setText( String.valueOf( output ) );
}

Answer 1

您似乎在C：\ wamp \ www \ Consult \ package.json中有一个package.json文件。

package.json文件指定npm应安装哪些软件包。

由于文件存在，npm默认使用它，但无法将内容解析为JSON。

您可以修复package.json文件，也可以将其删除并再次运行命令。

我建议您查看本指南：https://docs.npmjs.com/getting-started/using-a-package.json
