Jestjs 尝试安装jest cli时出错

当我运行

npm install--save dev jest cli

来安装jest时，出现以下错误：

> jest-cli@0.10.0 postinstall /var/www/html/_learning/react/hacking-book/node_modules/jest-cli
> node postinstall.js

{ [Error: Command failed: /bin/sh -c ./setup.sh
/bin/sh: 1: ./setup.sh: not found
]
  killed: false,
  code: 127,
  signal: null,
  cmd: '/bin/sh -c ./setup.sh' }

我从jest GitHub repo（）下载了

setup.sh

，并手动运行了它。然后我再次运行了

npm安装

，结果与上面相同。如何安装Jest
