一.SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". 这个报警告的原因简单来说时因为slf4j的版本和log4j的版本不匹配. 解决办法: 1.在你的maven库中查找你的slf4j版本,若有两个,最后选版本低的,因为本人选择高版本还是报错: 2.登陆该maven库网站: https://mvnrepository.com/search?q=slf4j 3.搜索slf4j,选择SLF4J LOG4J 12

最近写了个小插件报了个警告,然后去百度了一下,全都给我说extract-text-webpack-plugin这个插件有问题要更新,我也是无语了,这个插件我用都没用,百度翻了下齐刷刷全是这个答案,搞得我都怀疑自己然后把node_modules翻了一遍确定没有使用这个插件,后来去谷歌上搜了一下,第一条就告诉我为什么了,直白来说,webpack里的Tapable类的plugin已经废弃了,请使用hooks api来替代,那插件的代码怎么写呢 <script> // 旧的使用方法 class myP

前言 当写always组合逻辑块时,可能会写出 poor code.综合时软件会推断出锁存器.例如下面代码: always @* begin 'b1) begin w = (a & b) ^ c; end end 当c等于0的时候,w就会保持上一个值,所以就产生了锁存器,quartus就会贴心的给你报一个警告. inferring latch(es) for signal or variable "ram", which holds its previous value in
