运行npm安装wepy2踩坑error EEXIST 问题
windows 10安装wepy2
以前用过wepy1，现在要学习wepy2，运行以下命令出错
npm install @wepy/cli -g # 全局安装 WePY CLI 工具
打开log文件,与cmd界面提示一致,提示错误如下：
11758 error code EEXIST
11759 error path C:\Users\my\AppData\Roaming\npm\node_modules\@wepy\cli\bin\wepy.js
11760 error dest C:\Users\my\AppData\Roaming\npm\wepy
11761 error EEXIST: file already exists, cmd shim ‘C:\Users\my\AppData\Roaming\npm\node_modules\@wepy\cli\bin\wepy.js’ -> ‘C:\Users\my\AppData\Roaming\npm\wepy’
11762 error File exists: C:\Users\my\AppData\Roaming\npm\wepy
11763 error Remove the existing file and try again, or run npm
11764 error with –force to overwrite files recklessly.
根据提示判断我之前安装的wepy1与现在的wepy2安装有冲突，
找到目录C:\Users\my\AppData\Roaming\npm下删除文件wepy.js，
重新运行npm install @wepy/cli -g ，根据提示删除wepy，wepy.cmd
运行npm install @wepy/cli -g 安装成功。
