vue install five error encountered Summary

　　Foreword

　　　　This blog will not teach you how to install vue, but will inform the five problems that may be encountered during installation

　　　　 2017 I wrote install vue blog, details: https://www.cnblogs.com/tu-0718/p/7521099.html

　　5 error

　　　　①: If you use vue -V prompt command not found when the query is installed vue, may be you have not installed vue-cli Scaffolding (vue-cli can quickly create vue project)

　　　　　 ②: VUE installation Taobao mirror error, suggesting invalid configuration, you must be a fully qualified http address, because I url plus a front 1 blank spaces where no spaces

　　　　　　 Note: After installing Taobao mirroring, you need to use npm place can be used cnpm replaced, but it is recommended to install modules and plug-ins with cnpm , and start packing vue with npm

　　　　　　　　(Cnpm is the mirror, npm server in a foreign country, solid cnpm installation is faster, but may not lead to timely updates occur some unexpected problems)

　　　　　 ③: If the direct use npm run dev command will run error, suggesting no such file or directory, you need to create a project

　　　　　　 Use VUE WebPACK vue_test the init (vue_test project name) to create a project, and then be selected as necessary,

　　　　　　No (Y / n) let you select options directly enter if installed, the Y- mounted, the n- is not installed

　　　　　 ④: If enter the project directory, enter npm run dev when prompted did not find the item, explain your project path is wrong, check the project path and enter the command correctly

　　　　　 Here is the project path entered incorrectly, copy the path and paste directly into the git bash (equivalent to the windows of cmd ) will become a path slash '\' , should actually use '/' ,
