% npm install truffle-contract --save

原因是没有配置 github的ssh key，没有权限通过ssh下载github上的项目。

解决方法：

• 生成ssh key

  .ssh % ssh-keygen -t rsa -b 4096 -C "你的邮箱@163.com"
  Generating public/private rsa key pair.
  # 这里要输入rsa文件的位置，注意不要覆盖掉默认的，避免影响到已有的ssh连接
  Enter file in which to save the key (/Users/domino/.ssh/id_rsa): /Users/domino/.ssh/id_rsa_github
  # 直接回车到底
  Enter passphrase (empty for no passphrase):
  Enter same passphrase again:
  Your identification has been saved in /Users/domino/.ssh/id_rsa_github.
  Your public key has been saved in /Users/domino/.ssh/id_rsa_github.pub.
  The key fingerprint is:
  SHA256:0qmF2i4vW05EYxIZJv1TI5wv1zRldtmh1GDLp5g9mM0 [e-mail]
  The key's randomart image is:
  ………………
  

• 配置到 ~/.ssh/config文件中

  # 在 ~/.ssh/config文件中添加以下代码，如果没有则需要先创建
  
  #github
  Host *.github.com
  HostName github.com
  PreferredAuthentications publickey
  IdentityFile ~/.ssh/id_rsa_github
  

配置好重新执行安装命令，安装成功
