你好@thymjan, 根据您的安装日志，您的 Raspbian Jessey 中运行着两个 Node.js：Node.js v4.4.7（由 nvm 安装）和 Node.js v0.10（系统默认）。 我在你的日志中发现了这个错误： nvm is not compatible with the npm config "prefix" option: currently set to "/home/pi/.npm"
Run `npm config delete prefix` or `nvm use --delete-prefix v4.4.7` to unset it.
您更新的 npm 运行的是 Node.js v0.10，而不是 Node.js v4.4.7。要解决此问题，您可以删除该 export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" # This loads nvm
然后，确保您正在使用以下命令运行 Node.js v4： $ source ~/.bashrc
$ node -v
v4.4.7
之后，您可以运行以下步骤来安装 cncjs： $ npm install npm@latest -g
$ npm -v
3.10.5
$ npm install -g cncjs

亲爱的@cheton, 感谢您的快速回答和详细明确的说明！我一步步跟着他们。 然后……成功了！cnc 的安装没有问题，串行连接也没有问题。 非常感谢你！这是一个很好用的前端。 |
我已经尝试安装 cncjs 两次（按照指示）。服务器应用程序正在启动。
在客户端上调用服务器地址时，前端会出现。
但是在启动串行连接时每次都会出现错误，然后什么也没有发生：

你能告诉我哪里出了问题吗？
