gulp version mismatch的解决办法

最近在捣鼓gulp前端自动化工具，全局已经安装好了gulp，将命令行切换到自己项目中安装好gulp和gulp模块后执行，结果提示：

[gulp] Warning: Gulp version mismatch:
[gulp] Global gulp is 3.9.0
[gulp] Local gulp is 1.0.0

试过通过npm unistall gulp命令卸载，提示gulp不存在。遂google之…
然后找到了答案，英文原文：

There are two gulp versions. The CLI, and the project specific installed version.
To check the CLI and local version run: gulp -v
To check the Installed project version via npm run: npm ls and look for gulp
Update the project specific version to 3.3.4 to solve that issue.
From a terminal in your project folder:npm install gulp@3.3.4 –save

大概意思就是说手动指定版本安装，就可以解决。
用这个命令：npm install gulp@3.3.4 --save，这里的3.3.4可以改成你需要的版本，一般改成最新版的即可。
