如何使用NODE.JS运行ethereumjs

Question

大家好，我正在尝试使用以太坊

问题是我不能通过输入'testrpc‘来运行它。

我正在获取msg：

“未将‘testrpc’识别为内部或外部命令、可操作程序或批处理文件。”

知道为什么吗？

谢谢你

这是我的日志：

Answer 1

我认为你必须在全局安装它才能像这样运行它。或者，您可以将该目录添加到PATH

右键单击

“我的电脑”并转到Properties > Advanced System Settings > Environment Variables.

双击PATH下的'User variables for Username‘部分，然后添加

C:\Users\username\AppData\Roaming\testrpc

显然，用你的用户名替换“username”。

重新启动控制台窗口或IDE，您应该会从bower命令获得响应。

你需要在你的系统上全局安装testrpc ...

sudo npm install -g testrpc
