npm install gulp-sass的時候出現(xiàn)了這些錯誤

好唄赡盘，那我就npm install ajv@^6.5.5帆竹。然而不行竟趾。

在此之前我用yarn來install sass言缤，因為找不到ajv@^ 6.5.5所以可以選擇ajv@^ 6.5.4薯蝎，不過還是會報錯T0T

有看到類似情況的，https://github.com/sass/node-sass/issues/1781
折騰了半天献雅，沒搞定碉考。
好咯，我們轉(zhuǎn)回用npm 吧挺身，繞不過ajv@^6.5.5侯谁，然后我就找類似情況的https://stackoverflow.com/questions/44331005/npm-error-no-matching-version-found-for

The version you have specified, or one of your dependencies has specified is not published to npmjs.com
Executing npm view ionic-native (see docs) the following output is returned for package versions:
As you can see no version higher than 2.9.0 has been published to the npm repository. Strangely they have versions higher than this on GitHub.

好唄，我也來

npm view ajv

章钾。墙贱。。贱傀。惨撇。
哇奇跡發(fā)生了！ 安裝成功~
后續(xù)就接著裝sass窍箍，也OK了~串纺！嗚嗚嗚搞定。
