我是Chingu Voyage Project的贡献者。
运行npm run deploy时出现如下错误：
git-upload-pack '.': git-upload-pack: command not found
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! budget-app@0.1.0 deploy: `gh-pages -b master -d build`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the budget-app@0.1.0 deploy script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
我该如何解决这个问题？
