然后打开浏览器,输入http://127.0.0.1:3000,然后输入密码登陆成功后便可以进行命令行操作了,效果如下图所示,

5. 可能问题处理

5.1安装时报error: 'Use' is not a member of 'node::Buffer'

因为我安装的Node是4.1.1版本的,太新了。而wetty原本依赖的pty.js太老,导致编译出现的问题。修改以下wetty源代码目录下的package.json,将依赖的pty.js修改成最新版本0.3.0(原本是^0.2.7-1)。保存文件,然后重新运行sudo npm install命令即可。

5.2 ssh访问失败

启动wetty服务后,在浏览器中输入http://127.0.0.1:3000时报一个类似于下面截图的”ssh: connect to host localhost port 22: Connection refused”的错误。

运行以下下面的命令重新安装openssl-client和openssl-server即可,

$ sudo apt-get remove openssh-client openssh-server
$ sudo apt-get installopenssh-client openssh-server
