折腾：
【未解决】gitbook安装和使用插件autocover给生成的pdf文件加上封面
期间，去安装canvas：
npm install -g canvas dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.64.dylib Referenced from: /usr/local/opt/node@8/bin/node Reason: image not found [1] 95770 abort npm install -g canvas
试了多次，问题依旧。
难道是正在更新brew导致的？
好像不像啊
dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.64.dylib node@8/bin/node
那还是等会，等
【未解决】Mac中brew install报错：Error homebrew-core is a shallow clone
彻底弄好后，再去：
brew upgrade brew upgrade icu4c
或：
brew info icu4c brew switch icu4c 63.1
打算试试：
brew uninstall node icu4c brew install node
算了，不直接删除node。否则怕影响后续nodejs的版本和已安装插件的使用。
【已解决】Mac中brew install报错：Error homebrew-core is a shallow clone
然后继续：
npm install -g canvas dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.64.dylib Referenced from: /usr/local/opt/node@8/bin/node Reason: image not found [1] 1986 abort npm install -g canvas
问题依旧。
试试

会更新很多库。
不过没icu4c
操作完毕了
再去：
brew upgrade icu4c
结果：
brew upgrade icu4c Updating Homebrew... ==> Auto-updated Homebrew! Updated 1 tap (homebrew/cask). ==> Updated Casks Updated 3 casks. Warning: icu4c 67.1 already installed
再去试试：
npm install -g canvas
问题依旧。
brew cleanup
果然有：

icu4c/64.2被清理掉了。
再去试试，问题依旧。

和：

然后：
● brew link icu4c-67.1 Error: No such keg: /usr/local/Cellar/icu4c-67.1
去搜：
brew icu4c.rb
icu4c github
无法直接打开：

此处实在找不到，此处的
icu4c的67.1所对应的
算了，随便试试其旧版本：

算了，试试：

【总结】
此处：
npm install -g canvas dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.64.dylib Referenced from: /usr/local/opt/node@8/bin/node Reason: image not found
原因：
npm（内部的node8）所依赖的icu4c，其版本（由于更新了别的而）有变动，导致报错。
解决办法：
重新安装npm：
brew reinstall npm
即可。
