我无法安装我的项目套件

Question

在将expressJs安装到我的软件包时出现错误。 我不得不做一个npm cache clean --force no成功，然后删除了我的node_modules和package-lock.json ，我尝试使用npm i重新安装软件包，但仍然出现错误。

现在，我从PC Windows 10中删除了node.js ，下载并安装了最新的节点，然后尝试重新安装项目包。 现在我得到的错误是

$ npm i
npm ERR! Unexpected end of JSON input while parsing near '...ncies":{"autoprefixer'

npm ERR! A complete log of this run can be found in:
npm ERR!     C:\Users\Chioma Onyepere\AppData\Roaming\npm-cache\_logs\2019-05-28T20_26_29_676Z-debug.log

我的应用程序基于nextJs

这是package.json

显然是我的电脑出现了错误，原因是它在另一台电脑上工作正常。

我对npm不太了解，但是我建议尝试让它验证已经完成的安装，并以某种方式从现有安装中重写package.json文件。

https://docs.npmjs.com/cli/cache.html

即使安装失败并且package.json没有显示安装的任何痕迹，也可能只有npm知道某些工件妨碍了安装。
