我的package.json文件中有git依赖项。当我在react app文件夹中进行 sudo npm install 时，出现此错误

    npm ERR! code 1
    npm ERR! Command failed: /usr/bin/git clone --depth=1 -q -b master

这是我的package.json

package.json中的这一行引起了问题。

“ react-file-base64”：“ git + [https://github.com/lrojas94/react-file-

base64.git](https://github.com/lrojas94/react-file-base64.git) ”

这个问题令我震惊。请帮助。
