使用Capistrano，我注意到当用current -> /var/www/myapp创建一个符号链接时，需要一个永恒的编译。事实上，我等了大约5到10分钟并取消了这个过程。
它挂在这一部分：
00:09 deploy:assets:precompile
01 $HOME/.rbenv/bin/rbenv exec bundle exec rake assets:precompile
01 yarn install v0.27.5
01 [1/4] Resolving packages...
01 [2/4] Fetching packages...
01 warning fsevents@1.1.2: The platform "linux" is incompatible with this module.
01 info "fsevents@1.1.2" is an optional dependency and failed compatibility check. Excluding it from installation.
01 [3/4] Linking dependencies...
01 [4/4] Building fresh packages...
如果删除current符号链接，它仍然需要一段时间，但它会完成。
00:09 deploy:assets:precompile
01 $HOME/.rbenv/bin/rbenv exec bundle exec rake assets:precompile
01 yarn install v0.27.5

大约134s。
首次使用Capistrano和webpacker进行部署，是正常还是有解决方案来缩短编译时间？
