Ruby更新無法使用兩種方法
我嘗試在我的 mac 10.6.8 上安裝 ruby 版本 1.9.3：

There were package installation errors, make sure to read the log.然後嘗試使用 MacPorts 安裝，但它也沒有再次工作。有任何想法嗎？
Oskar-Niburskis-MacBook-Pro:~ oskarniburski$ sudo port install ruby19 Warning: Xcode does not appear to be installed; most ports will likely fail to build. ---> Computing dependencies for ruby19Error: Unable to execute port: can't read "build.cmd": Failed to locate 'make' in path: '/opt/local/bin:/opt/local/sbin:/bin:/sbin:/usr/bin:/usr/sbin' or at its MacPorts configuration time location, did you move it?這是我現在的路徑：
/opt/local/bin:/opt/local/sbin:/usr/local/git/bin:/usr/X11/bin:/Users/oskarniburski/.rvm/bin:/usr/X11R6/bin:/Library/Frameworks/Python.framework/Versions/3.3/bin:/Library/Frameworks/Python.framework/Versions/2.7/bin:/Library/Frameworks/Python.framework/Versions/Current/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/git/bin:/usr/X11/bin:/Users/oskarniburski/.rvm/bin
‘which -a make’ 和 locate -b ‘\make’ 都不是。第一個沒有找到哪個命令，後者的定位：非法選項–b
問題1：
make第一個問題是 ruby 需要編譯，這通常是通過
make從 a 讀取設置Makefile然後呼叫編譯器來完成的。在 OSXmake上安裝了Xcode它的工具，/Developer/usr/bin而不是/usr/bin預期的位置。此目錄不在預設目錄中，$PATH因此 shell 找不到其中的任何執行檔。您可以通過將此行添加到您的
~/.bash_profile（確保export $PATH在行之前添加它）為您的使用者解決此問題：PATH="/Developer/usr/bin:$PATH"
sudo但是，任何以 root 身份執行的命令（例如）仍然無法訪問它。我建議您將此目錄添加到預設路徑。打開/etc/profile，找到定義路徑的行並將目錄添加到其中。我在 Linux 系統上，但它應該看起來像這樣：PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"只需將目錄添加到末尾，如下所示：
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/Developer/usr/bin"如果您不想更改預設值，可以連結
make到預設值中的目錄$PATH：sudo ln -s /Developer/usr/bin/make /usr/bin您必須對其中的所有內容執行此操作，
/Developer/usr/bin因此我真的建議您更改預設設置。問題2：尋找新版本
此時您應該能夠安裝 ruby
$ sudo port install ruby19正確退出，但您的 ruby 版本似乎沒有更新：
$ ruby --version ruby 1.8.7 (2012-02-08 patchlevel 358) [universal-darwin10.0]這是因為，預設情況下，
port將其文件安裝在/opt/local其中並將您的 ruby 執行檔安裝為/opt/local/bin/ruby1.9. 另一個不在您的$PATH. 因此，您可以重複上述過程並添加/opt/local/bin到您的$PATH，或者您可以將ruby1.9執行檔連結到您路徑中的目錄。如果你添加/opt/local/bin到你的$PATH，你將能夠執行 v1.8ruby和 v1.9ruby1.9。如果您希望所有現有腳本都切換到 v1.9，我建議您/usr/bin/ruby指出新版本。舊版本
/usr/bin實際上是一個符號連結：$ ls -l /usr/bin/ruby rwxr-xr-x 1 root wheel 76 25 Jun 2010 /usr/bin/ruby -> ../../System/Library/Frameworks/Ruby.framework/Versions/Current/usr/bin/ruby這意味著您可以安全地刪除它並用指向新版本的連結替換它：
$ sudo rm /usr/bin/ruby; sudo ln -s /opt/local/bin/ruby1.9 /usr/bin/ruby如果您想恢復並
ruby執行 v1.8，只需執行反向命令：$ sudo rm /usr/bin/ruby; sudo ln -s /System/Library/Frameworks/Ruby.framework/Versions/Current/usr/bin/ruby /usr/bin/ruby如果一切順利，您
ruby現在的預設值為 v1.9：$ ruby --version ruby 1.9.3p448 (2013-06-27 revision 41675) [x86_64-darwin10]
