在VueX中部署web3时出现以下问题：
TypeError：重复的方法构造函数。此方法被定义为RPC调用和Object方法。
我推断问题出在setupWeb3 Action中的web3声明中（见下文）。
我猜是打字的问题吧？
我在main.ts中声明了一个全局名称空间，如下所示：

declare global {
  interface Window {
      ethereum:any;
      web3:any;
  }
}

以下是我的行动：

export const actions: ActionTree<Network, RootState> = {
    setupWeb3(context: ActionContext<Network, RootState>) {
        let web3;
        if (window.ethereum) {
            web3 = new Web3(window.ethereum);
            window.ethereum.enable().then(enabled => console.log(enabled));
        } else if (window.web3) {
            web3 = new Web3(window.web3.currentProvider);
        } else {
            // TODO better handle of metamask
            window.alert(
                'Non-Ethereum browser detected. You should consider trying MetaMask!',
            );
        }
        context.commit('SET_WEB3', web3);
    },
    async getNetworkData(context: ActionContext<Network, RootState>) {
        const { Web3 } = context.getters;
        const network = await Web3.eth.net.getNetworkType();
        const networkId = await Web3.eth.net.getId();
        const currentBlock = await Web3.eth.getBlockNumber();
        context.commit('SET_NETWORK_DATA', {
            network,
            networkId,
            currentBlock,
        });
    },
    getAddress(context: ActionContext<Network, RootState>) {
        const { Web3 } = context.getters;
        Web3.eth.getAccounts().then((account: string[]) => 
            context.commit("SET_ADDRESS", account[0]));
    },
    bootstrapContracts(context: ActionContext<Network, RootState>) {
        const setupWeb3 = context.dispatch('setupWeb3');
        const network   = context.dispatch('getNetworkData');
        const address   = context.dispatch('getAddress');
        Promise.all([setupWeb3, network, address,])
            .then(() => {
                context.dispatch('setupLootControls');
            });
    },
};
