1. NPM 命令執行 報錯

D:\webworkspace\WebpackDemo>npm -v
module.js:327
    throw err;
    ^

Error: Cannot find module 'semver'
    at Function.Module._resolveFilename (module.js:325:15)
    at Function.Module._load (module.js:276:25)
    at Module.require (module.js:353:17)
    at require (internal/module
 
.js:12:17)
    at Object.<anonymous> (C:\Users\yuan\AppData\Roaming\npm\node_modules\npm\lib\utils\unsupported.js:2:14)
    at Module._compile (module.js:409:26)
    at Object.Module._extensions..js (module.js:416:10)

    at Function.Module._load (module.js:300

    at Module.require (module.js:353:17)

解決：

刪除下面目錄即可，重新執行！

C:\Users\yuan\AppData\Roaming\npm
C:\Users\yuan\AppData\Roaming\npm-cache

2. ESLint 字串模板

Problem with ESLint reformatting:
            xxx.js: Unexpected template string expression. (no-template-curly-in-string) (show balloon)
 

解決：

使用鍵盤 tab鍵上面的引號 ，非 enter 鍵旁邊的引號
