ln: failed to create symbolic link ‘/usr/local/bin/node’: File exists

运行命令时 ln -s /usr/local/node/node-v10.9.0-linux-x64/ben/node /usr/local/bin/node

报这个错

ln: failed to create symbolic link ‘/usr/local/bin/node’: File exists

是因为已经存在了

解析方法有两种

1.删除

/usr/local/bin/node

2.覆盖

ln -sf /usr/local/node/node-v10.9.0-linux-x64/bin/node /usr/local/bin/node
