Solution:
解决方案：
npm cache clean --force
then try again to create your app (here when creating a react app) or install what you were about to install.
然后再次尝试创建您的应用程序（创建反应应用程序时在此处）或安装您将要安装的内容。
create-react-app myproject
(creating react app)[same npm problem that can occur in different operation]
（创建react app）[不同操作中可能出现的相同npm问题]
npm install -g @angular/cli@latest
(installing angular cli (or installing anything else))
（安装 angular cli（或安装其他任何东西））
It will work.
它会起作用。
explanation:
解释：
That's a problem related to npm, it's about the cache that get corrupt. Even though in newer versions of npm they implemented self healing, which normally guarantee no corruption, but it seem it's not that efficient.
Forcing clean cache resolve the problem.
这是一个与 npm 相关的问题，它与缓存损坏有关。即使在较新版本的 npm 中，它们实现了自我修复，通常可以保证不会损坏，但似乎效率不高。
强制清理缓存解决了问题。
The error happen when parsing one of the cache files, which have a json format. The cache is found at ~/.npm/_cacache (in linux) and %AppData%/npm-cache (windows). For my current npm version and when i checked, there was three directories.
解析具有 json 格式的缓存文件之一时会发生错误。缓存位于 ~/.npm/_cacache（在 linux 中）和 %AppData%/npm-cache（在 Windows 中）。对于我当前的 npm 版本，当我检查时，有三个目录。
if you check the first or the second, the structure is as follow
如果你检查第一个或第二个，结构如下
And each cache file have a json format (and that what get parsed)
每个缓存文件都有一个 json 格式（以及解析的内容）
Here a good link from the doc: https://docs.npmjs.com/cli/cache
这是文档中的一个很好的链接：https: //docs.npmjs.com/cli/cache
