我在项目中安装react-dom、react 和next 时遇到问题。我的项目中只有两个文件：index.js 和 package.json（我刚刚创建的文件是空的）。但当我跑步时
npm install react@latest react-dom@latest next@latest
在终端中它返回一个错误：
npm ERR! code EJSONPARSE
npm ERR! path C:\WEBSITES\Projets de la premiere cliente\platformes vente places d'installation/package.json
npm ERR! JSON.parse Unexpected end of JSON input while parsing empty string
npm ERR! JSON.parse Failed to parse JSON data.
npm ERR! JSON.parse Note: package.json must be actual JSON, not just JavaScript.

我尝试运行“npm clean cache”，但它不起作用。它返回给我一个错误：
npm ERR! As of npm@5, the npm cache self-heals from corruption issues
npm ERR! data extracted from the cache is guaranteed to be valid. If you
npm ERR! want to make sure everything is consistent, use `npm cache verify`
npm ERR! not likely to correct any problems you may be encountering!
npm ERR!
npm ERR! On the other hand, if you're debugging an issue with the installer,
npm ERR! or race conditions that depend on the timing of writing to an empty
npm ERR! cache, you can use `npm install --cache /tmp/empty-cache` to use a
npm ERR! temporary cache instead of nuking the actual one.
npm ERR!
npm ERR! If you're sure you want to delete the entire cache, rerun this command
npm ERR! with --force.
您需要初始化package.json文件。首先，使用以下命令删除当前的 package.json 文件：
rm -rf package.json
之后，使用以下命令创建一个新的 package.json 文件：
npm init -y
它会起作用的！该错误是由于 package.json 文件为空（或创建不正确）而引起的。因此，当您尝试安装依赖项时，它无法将它们添加到文件中。
希望对您有所帮助！
