“ npm ERR！解析附近时JSON输入意外结束。缓存清理不起作用

Question

自2天以来，我一直在尝试“ npm安装”。论坛上几乎所有其他类似问题的答案都表明，“ npm cahce clean -f”解决了问题。

但是，对我而言，这两种情况都不起作用-1.用于在全球范围内安装新软件包，2.用于为现有项目安装本地软件包

我尝试同时使用两个备用注册表（https://registry.npmjs.org/和http://registry.npmjs.org/）。而且我也没有任何代理人。

我正在使用- Windows 7旗舰版， 节点版本：10.14.1， NPM版本：6.4.1

我也尝试过降级以使用Node8.x。但是，这也不行。

我的项目中的Package.json

另一方面，这是全局安装软件包时的错误快照...
