Typescript 将 can 绑定到能力实例时出错

Question

Simply pasting example code from docs

import { createCanBoundTo } from '@casl/react';

import ability from './abilities';

export const Can = createCanBoundTo(ability);

Gives error on last line:

Exported variable 'Can' has or is using name 'BoundCanClass' from external module "C:/Users/ahmefa04/Documents/SourceCode/temp-cd-next/node_modules/@casl/react/dist/types/factory" but cannot be named.ts(4023)

Edit: I exported BoundCanClass in the factory.d.ts file however when I try to use can in my application:

<Can I="view" on="all">
        <Button size="small" onClick={handleUpdateRow}>
          Update a user
        </Button>
</Can>

I get error:

No overload matches this call. Overload 1 of 2, '(props: BoundCanProps<Ability<AbilityTuple<string, Subject>, { published: boolean; }>>, context?: any): Can<Ability<AbilityTuple<string, Subject>, {...; }>, true>', gave the following error.

Answer 1

The problem happens because I should be used with a , an or this props, to use on you should use do instead:

<Can I="view" a="all">
   <Button size="small" onClick={handleUpdateRow}>
      Update a user
    </Button>
</Can>

or

<Can do="view" on="all">
   <Button size="small" onClick={handleUpdateRow}>
      Update a user
    </Button>
</Can>
