当我在运行 npm install 命令后收到错误时，如何从 github 克隆我的 react 项目后运行

Question

所以我首先运行 git clone http://........... 并成功下载项目

然后我运行 cd 来更改目录。这行得通！

我在目录下运行npm install，cmd行显示如下错误

npm ERR! code EJSONPARSE
npm ERR! path C:\Users\Home\Documents\Ctr-Alt-Elite/package.json
npm ERR! JSON.parse Unexpected token "<" (0x3C) in JSON at position 625 while parsing near "...us-bar\": \"~1.1.0\",\r\n<<<<<<< HEAD\r\n    \"f..."

下面是debug.log文件

看起来有人在 package.json 中提交了合并冲突，导致 JSON 无效。要解决此问题，请转到 package.json 并解决冲突。 Here 是一篇解释手动合并所需的所有内容的文章。它的要点是冲突看起来像这样：

<<<<<<< HEAD
// Here is the code for your version/branch
=======
// Here is the version from the version/branch you're merging in
>>>>>>> <branch-/tagname or commitref>

然后你需要手动决定应该从两个版本中保留什么，当然，删除标记。
