推荐答案
我遇到了同样的问题，并通过将'npm'目录添加到我的PATH中来解决了这个问题:
I had this same problem and fixed it by adding the 'npm' directory to my PATH:
右键单击我的电脑"，然后转到属性>高级系统设置>环境变量".
Right click 'My Computer' and go to '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 \用户名\ AppData \ Roaming \ npm"，显然用您的用户名替换了用户名". 根据下面的注释，您可能需要将其添加到路径的顶部/顶部.
Double click on PATH under the 'User variables for Username' section, and add 'C:\Users\username\AppData\Roaming\npm' obviously replacing 'username' with yours. Based on comments below, you may need to add it to the top/front of your path.
重新启动控制台窗口或IDE，您应该从bower命令获得响应.
Restart your console window or IDE and you should get a response from the bower command.
