备注

我已经将 npm 从 6.9.0 升级到 6.14.5 然后也面临同样的问题

我已经删除了 package.json.lock 和 node_modules 然后也面临同样的问题

请让我知道我还缺少什么？

如果您看到日志，对于旧包，它会给出警告而不是错误。错误实际上是这一行:npm ERR! Unexpected end of JSON input while parsing near '...on" : "10.16.3"npm ERR!}'由于您没有包含整个日志，因此我可以猜测这可能是由于引用未正确解决而导致的歧义问题!
以管理员权限打开命令提示符/powershell/终端等。请按以下步骤操作:-

sudo npm cache clean --force

sudo npm cache verify

删除 package-lock.json文件位于 C:\Users\<your_username>

现在尝试使用 npm i 从您的项目文件夹安装您的项目依赖项.
注意: - 如果这不起作用，请按照与上述相同的过程(再次)卸载 npm和 node并重新安装它。它应该工作!
