Mac Gems: Meet the Developers was a great Main Stage discussion at #Macworld2014! Longtime Mac users know that one of the most common causes of problems with applications or the OS itself is a corrupt preference file. Finding and disposing of these damaged files is one of the.

And with a specific version: brew gem install heroku 3.8.3 -homebrew-ruby. To upgrade: brew gem upgrade heroku. To uninstall: brew gem uninstall heroku. To check information: brew gem info heroku. Note: Installed gems are listed in brew list with prefix of gem-, like gem-heroku. Gems will be installed into /usr/local/bin and every user on your system can use them if it's in their PATH. Option 2: Install in your home directory (without sudo) The following will install gems in /.gem and put binaries in /bin (which you should then add to your PATH). Gem install fakes3 -user-install -n/bin.

Our Verdict
One of the best features introduced in Lion (OS X 10.7), and available on every version of OS X since, is OS X Recovery. The OS X installer creates an invisible, bootable, 650MB partition—a portion of a drive that the operating system treats as a separate volume—on your startup drive called Recovery HD that includes a few essential utilities for fixing problems, restoring files, browsing the Web, and even reinstalling OS X.
The Lion, Mountain Lion, and Mavericks installers should automatically create the invisible Recovery HD partition the first time you install one of these operating systems. However, that doesn’t always happen. You can find out if your Mac has the Recovery HD partition—and, thus, OS X Recovery capabilities—by launching the Terminal app (in /Applications/Utilities), and then typing diskutil list and pressing Return. Locate your Mac’s startup drive in the resulting list of volumes; if you have a Recovery HD partition, it will show up as “Recovery HD” (preceded by “Apple_Boot”) just below the name of the startup drive. If you don’t see a Recovery HD partition on your Mac’s startup drive, you can’t use OS X Recovery.
(Another situation where you may need to add a Recovery HD partition is when you have an external drive you use for clone backups and you want to enable FileVault on it—a drive must have a Recovery HD partition to use FileVault.)
If you don’t have a Recovery HD partition, Apple’s official procedure for adding one is to back up your drive, erase it to make sure it’s properly formatted, reinstall OS X—which should create the hidden partition—and then restore your data.
But an easier approach is to use the free Recovery Partition Creator (more info here). This app can create the partition and even install the necessary OS X Recovery software on it. You just need to have a copy of your OS X installer—Mavericks, Mountain Lion, or Lion—on a connected drive.
Warning: Recovery Partition Creator alters your drive’s partition map, which isn’t a trivial action.Beforeusing the utility, youmustback up your drive (and test your backup). I didn’t experience any data issues when testing Recovery Partition Creator, but whenever you use a utility that works with your drive at such a low level, you want to be safe.
Launch Recovery Partition Creator, read the disclaimer (which also reminds you to back up your drive—you did, right?), and click OK. You’ll then see a dialog box indicating the version of OS X installed on your Mac. Assuming it’s some version of 10.7, 10.8, or 10.9, you’ll see the message “continuing”; click OK. Next you’ll be prompted to choose the connected volume on which you want to create the recovery partition—presumably, this would be your startup drive, but you can also use Recovery Partition Creator to create the partition on a different drive. Choose the drive and click OK.
Recovery Partition Creator will next check your drive for errors. You can skip this step, but I recommend letting it continue—you don’t want a utility mucking with your drive’s partition map if the drive or its directory is having problems.
You’ll then be asked to locate your OS X installer. Because Recovery Partition Creator will use the chosen installer to populate the new partition with the necessary OS X Recovery software, you’ll want to choose the installer for the version of OS X you’re running on your Mac. In other words, if your Mac is running Mavericks, you want to choose the Mavericks installer. Oddly, even though you’ve just chosen the installer, you’re asked to choose the OS version you’re going to install on the recovery partition. Click the correct version (10.7 or 10.8 is one choice, 10.9 is the other), and Recovery Partition Creator will begin repartitioning the drive and installing the necessary software.
The description here makes Recovery Partition Creator seem more complicated than it actually is. In practice, the steps are quick and mostly straightforward. However, the utility is an AppleScript-based app, which means you don’t get much feedback about what’s happening. Eventually—after a minute or so, or a few minutes, depending on the speed of your drive(s)—you’ll see an alert that the procedure was successful. (If you switched to another app to work while Recovery Partition Creator was doing its thing, this alert may be hidden behind other windows.) You can then quit the utility.
If you want to verify that Recovery Partition Creator did what it promised, you can open Terminal and repeat the diskutil list command. The drive in question should now show a Recovery HD partition.
I’ve tested Recovery Partition Creator on a number of drives—for example, my iMac, which somehow never got one despite many OS X installations, and a couple backup drives for which I wanted to enable FileVault—and it’s worked well. It’s a handy tool to have around.

Разработчики Tesseract изменили довольно много вещей в версии 3.0.4, и Tesseract-ocr gem потерял совместимость с ним. Лучшее решение, которое я вижу, - это понижение рейтинга на данный момент. Возможно, на вашем mac установлены предыдущие версии Tesseract, используйте brew info tesseract, чтобы узнать это. Если да, то просто используйте brew switch. Недавно я сделал brew cleanup, поэтому мне пришлось удалить tesseract и установить его из старой формулы, например:
Это установит Tesseract 3.02. 02_3d, который, кажется, работает.Вы можете найти больше информации и отследите эту проблему по адресуTesseract-ocr repo .

Если вы не хотите понизить Tesseract, альтернативным быстрым и грязным методом было бы выполнить Tesseract как команду оболочки и открыть файл, который она сохраняет, чтобы получить доступ к содержимому (Примечание: интерполяция строк работает в командах оболочки)

Из сгенерированного журнала он показал, что мне не хватает заголовочного файла, проблема со мной была в том, что я ссылался на неправильную версию, поэтому,добавление этого кода в файл gem решило проблему для меня
