大家好，iam，我想和ethereumjs一起工作
问题是我无法通过键入“ testrpc”来运行它
正在获取味精：
“'testrpc'无法识别为内部或外部命令，
可操作的程序或批处理文件。”
知道为什么吗？
感谢你

最佳答案
我认为您必须在全局安装它才能像这样运行它。
或者，您可以将目录添加到您的PATH中：
右键点击
我的电脑”，然后转到Properties > Advanced System Settings > Environment Variables.
双击“用户名的用户变量”部分下的PATH，然后添加
C:\Users\username\AppData\Roaming\testrpc
显然将“用户名”替换为您的用户名。
重新启动控制台窗口或IDE，您应该从bower命令获得响应。
