1、今天在Mac下运行npm命令时不知什么原因报错如下:

☁  myhexo_blog [master] ⚡ node -v                            
dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.59.dylib
  Referenced from: /usr/local/bin/node
  Reason: image not found
[1]    33278 abort      node -v

2、解决方案：

☁  myhexo_blog [master] ⚡ brew uninstall --force node 
Uninstalling node... (4,152 files, 47.9MB)
☁  myhexo_blog [master] ⚡ brew uninstall icu4c && brew install icu4c 
Error: Refusing to uninstall /usr/local/Cellar/icu4c/63.1
because it is required by php and php@7.1, which are currently installed.
You can override this and force removal with:
  brew uninstall --ignore-dependencies icu4c
☁  myhexo_blog [master] ⚡  brew unlink icu4c && brew link icu4c –force
Unlinking /usr/local/Cellar/icu4c/63.1... 0 symlinks removed
Error: No such keg: /usr/local/Cellar/–force
☁  myhexo_blog [master] ⚡ brew install node

3、之后运行node -v显示如下:

☁  myhexo_blog [master] ⚡ node -v
v11.8.0

问题解决~ happy hacking...
