Answer 1

第一次尝试

public class Main {

    public static void main(String[] args) {
        int[] arr1 = {1};
        double[] arr2 = {1.0};
        System.out.println(Test.identity(arr1));
        System.out.println(Test.identity(arr2));
    }
}

public class Test {
    public static <T extends Comparable<T>> T[] identity(T[] x) {
        return x;
    }
}

或下一个：

尝试安装

npm install -g react-navigation

首先备份节点模块中的所有依赖项。

获取有关npm install @react-navigation/native的信息使用此文件，您可以知道是否已经安装了哪些依赖项（如果需要），您可以重新安装npm，然后再次执行package.json

Answer 2

似乎<button class="btn btn-default btn-lg" onclick="ConfirmDialog('Are you sure you want To Download?')">Download</button> <br /><br /> <div id="overlay"> <div id="text"> <img src="~/assets/images/loadingimage.gif" style="width:5%;" /><span>   Downloading....</span> </div> </div> <label class="error-msg" style="color:green;" itemid="lblmsg"></label>软件包不正确。因此，您可以重新安装它或重新安装整个<script type="text/javascript"> function ConfirmDialog(message) { debugger; var x = window.confirm(message) debugger; if (x) { on(); $.ajax({ url: '@Url.Action("YourMVC_Method", "Controller")', type: 'GET', contentType: 'application/json;charset=utf-8', success: function (result) { debugger; $("label[itemid='lblmsg']").show(); $('label[itemid="lblmsg"]').text('DownloadSuccess'); off(); }, error: function (ex) { //alert(ex); $('label[itemid="lblmsg"]').hide(); off(); } }); } else { $('label[itemid="lblmsg"]').hide(); off(); } } function on() { document.getElementById("overlay").style.display = "block"; } function off() { document.getElementById("overlay").style.display = "none"; } </script>。

首先，备份您的hoist-non-react-statics文件夹。这个非常重要！然后删除node_modules文件夹，并用node_modules重新安装npm软件包。

完成上述操作后，尝试再次安装node_modules。
