你好。这可以在 Raspberry Pi B+ 上运行吗？

我用 NPM 安装了它，但它失败了……

梅克兰茨

Protoneer，我让它在 RPi B+ 和 RPi 2 上运行，两者都带有 Wheezy 和 Jessie。起初我对包裹有些奇怪，但不记得细节了。

您看到的错误是什么？

质子

我尝试从 npm 安装它，但串行库存在问题。

将尝试为您获取日志……

您运行的是哪个版本的 Node.js？如果您运行的是 Node v4 或 v5，则需要使用 gcc/g++ v4.8 或更高版本才能正确编译 serialport 模块。

梅克兰茨

在我的一个系统上的 cnc.js 版本升级期间，我不得不在某一时刻直接安装 serialport。在两个不同的 Pi 上一切正常，一个运行节点 v0.12.1，一个运行节点 v5.2.0。

在node v5.2.0版本上，我无法升级到cnc.js v0.14，直到我卸载了以前的版本，然后它才能正常工作。

你好@cheton,@meikrantz. 让我们重新开始。我想为 Raspberries 创建一个 img 文件，以配合我的 RPI CNC 板。目前我有 bCNC 正在工作，但我想添加 CNC.js 作为替代方案。（我创建的脚本在创建图像之前设置 RPI 环境：https ://github.com/Protoneer/RPI-CNC-Config -脚本/树/主/脚本）

查看 Wiki，不清楚我需要 CNC.js 的 NodeJS 版本。RPI Jesse 目前附带 0.10.29…哪个版本最适合目标？

质子

下面是我的安装日志…

我设法从 Adafruits 教程将 Node 升级到 0.12.6。
https://learn.adafruit.com/node-embedded-development/installing-node-dot-js

然后执行“sudo npm install -g cncjs”并出现以下错误。（运行时间很长）

我错过了一步吗？

嗨 Protoner，

您可以尝试添加prefix=~/.npm到您的~/.npmrc. 例如：

[cheton@piduino:~]
$ echo "prefix=~/.npm" >> ~/.npmrc

[cheton@piduino:~]
$ cat ~/.npmrc 
prefix=~/.npm

之后，您可以在cncjs不使用的情况下进行安装sudo：

[cheton@piduino:~]
$ npm install -g cncjs

这应该可以解决您在 Raspberry Pi 上的安装问题。

奇顿

我更新了 README.md 中的安装指南。
https://github.com/cheton/cnc.js#installation

质子

@cheton，现在我们正在用煤气做饭！！！

您的建议解决了错误。我现在面临的唯一问题是运行“cnc”返回“未找到命令”… 我也重新启动了 RPI。

知道那可能是什么吗？

奇顿

它可能安装在~/.npm/node_modules/目录中。如果是这样，请附加~/.npm/bin到~/.bash_profile或中的 PATH 环境~/.bashrc，如下所示：

export PATH=$PATH:~/.npm/bin/

质子

谢谢@cheton. 我设法让它继续下去。出于某种原因，我不能去“cnc”，我必须去
“./cnc”或“node cnc”。

否则我已经连接到 GRBL 并四处移动了东西。

奇顿

好的。如果您有其他问题或遇到任何问题，请随时告诉我。

质子

谢谢@cheton… 我很惊讶我现在只看到了 CNC.JS。它看起来非常精致且经过深思熟虑。做得好！！！
