找不到地方来调整导致此错误的设置(严格模式).请帮忙.谢谢
Can't find a place to adjust the settings causing this error (strict mode). Please help. Thanks
推荐答案
通过取消选中 Task Runner 使用的 Node.js 二进制文件的复选框来解决问题:
Issue solved by un-checking the box for the Node.js binary used by Task Runner:
在菜单中，进入 Tools > Options > Projects and Solutions > Web Package Management > External Web Tools 并取消选择 $(VSINSTALLDIR)WebExternal
In the menu, go to Tools > Options > Projects and Solutions > Web Package Management > External Web Tools and DESELECT the option for $(VSINSTALLDIR)WebExternal
该目录下安装的版本显然不支持ES6.
The version installed in that directory doesn't support ES6 apparently.
解决方案参考这里 和这里.
