laravel mix extract之后.scss编译出来是空文件

Submitted by gouki on 2019, September 15, 2:07 PM

应该不算是我姿势不对吧，网上不少人有这个问题：https://github.com/JeffreyWay/laravel-mix/issues/1914。

其实代码非常简单，如果是这样：

JavaScript代码

mix
.js('resources/front/visitors/visitors.js', 'public/js')
.sass('resources/front/visitors/sass/visitors.scss', 'public/css')

那就一切正常。如果加了这么一行：

JavaScript代码

mix
.js('resources/front/visitors/visitors.js', 'public/js')
.sass('resources/front/visitors/sass/visitors.scss', 'public/css')
.extract([....])

则生成出来的visitors.css为空文件。生成空文件的时候，还认为自己是从几个vue文件里做了提取。但事实上scss这个文件是孤立的。不含在vue里（确实是有一个提取vuestyle的参数，但我没设置），laravel-mix的作者居然说：No, answer is don't upgrade if you're using dynamic imports. See the Mix 4 release notes.

评论里有人说实在不行就分成两个js文件来处理吧。嗯，事实上我也这样做了，比如我我因为前后台分开，就这么折腾的，但也会带来问题，比如，后一个生成的manifest.json会覆盖前面的（如果你不用{{mix()}}函数，那不会遇到这个问题，因为你不用它。。。但如果你用了，就会遇到各种不同的小问题，除非你放在一个mix.js文件里，只是用路由来解决）

最后我确实是分拆了，利用了concurrently，直接加了一个scripts:

JavaScript代码

{
"start":"concurrently \"npm:watch*\""
}

执行npm run start，就OK了。如果你不想看完整的输出。上面的scripts中可以改成：

JavaScript代码

{
"start":"concurrently -r \"npm:watch*\""
}

是的，你没有看错，就加了一个-r的参数

brew 切换为交大源

Submitted by gouki on 2019, September 15, 9:17 AM

之前用中科大的，但好象中科大有缺失源，或者有时候在update的时候会卡。所以换到了上海交大的源

一句话的命令：

cd "$(brew --repo)" && git remote set-url origin https://mirrors.sjtug.sjtu.edu.cn/git/brew.git && cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core" && git remote set-url origin https://mirrors.sjtug.sjtu.edu.cn/git/homebrew-core.git && cd "$(brew --repo)"/Library/Taps/homebrew/homebrew-cask && git remote set-url origin https://mirrors.sjtug.sjtu.edu.cn/git/homebrew-cask.git && echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.sjtug.sjtu.edu.cn/homebrew-bottles' >> ~/.bash_profile

说白了，就是改了：brew,brew-core,brew-cask,和brew-bottles的信息其他没啥

速度是真快了很多。

当然话说回来。中科大的源，说明文件是最详细的。。。。交大的，就一句话。

Pentaho data integration(kettle) 在mac上无法运行

Submitted by gouki on 2019, September 14, 10:35 AM

Pentaho data integration ，从官方下载下来最新的安装包，解压之后，双击Data Integration，报安全问题，询问是否打开，同意并输入自己的开机密码。然后，等了几秒，发现没有任何反应，再次双击Data Integration，依然没有任何相应。

以为程序不兼容。但想想不应该，搜了一下，发现可能是权限的问题，说是直接运行 spoon.sh 可以运行。试了一下，确实OK。但不可能一直这样执行。继续找解决方案，最后居然是这么简单，运行一下：

XML/HTML代码

sudo xattr -dr com.apple.quarantine ~/Downloads/data-integration/Data\ Integration.app

这个问题在2017年就有人遇到了，看这里：https://edpflager.com/?p=3571，参考一下即可。

现在，程序终于可以运行了

最后附上一堆教程：

我可能错怪layerstack了

上一篇博客说了。我用vsc的ssh-remote的时候，30秒或者1分钟必断。错误信息一直就类似：

[04:30:38.608] "install" terminal command done
[04:30:38.609] Install terminal quit with output:

重连后也是

发了ticket给layerstack。他们测试也来没有这个问题。我开始以为是什么openfiles limit的问题。也打开到最大了。

期间调整了一下这个：echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p，因为开始有报inotify max error

直到他们给我发了一个ticket：

Thank you for your patience in this matter.

We have investigated the issue in detail and we are not able to recreate the issue from our end. We have checked the same from multiple locations and find out its working fine.

The reported issue seems to be related to your local ISP, so we suggest you to change the standard port (22) of SSH to some other non standard port like 2222 or 2244, in server and recheck the issue.

Please do have a check on our above suggestion and let us know if you still face any issues in accessing.

所以我就想了一下，直接把PORT改成了2222，2223，2244，然而仍然失败，最后我用了一个超大端口，居然正常了
