npm无法安装sharp

sharp包是基于node.js的高性能图片处理器

但是在使用npm/yarn对sharp安装时经常会出现安装失败的问题，主要原因是安装源的问题所以我们可以选择为包管理器换源或者手动下载并安装。

换源

三个命令只执行一个即可

• 使用镜像地址（仅设置sharp）：

npm config set sharp_binary_host "https://npmmirror.com/mirrors/sharp"
npm config set sharp_libvips_binary_host "https://npmmirror.com/mirrors/sharp-libvips"

复制

• 推荐将npm源都修改为cnpm

npm config set registry https://registry.npmmirror.com

复制

• yarn修改方式

yarn config set registry https://registry.npmmirror.com

复制

手动下载

• 提前下载好sharp某版本号对应的libvips依赖包，放在npm的缓存路径中，通常这个路径是/Users/<username>/.npm/_libvips（在使用了nvm管理node版本的情况下，正常情况下执行1操作后就没有问题了）

如果没有提前下载好并放在缓存中，可能会出现如下的报错信息
