Vagrant - 攤鋪機devstack錯誤：「[Errno 20]不是目錄」

Question

我試圖讓安裝了Vagrant的edx Devstack，我在Windows機器上。我收到的錯誤似乎是由Windows不支持的符號鏈接導致的。

根據Dealing with line endings and symlinks under Windows下的edx故障排除指南，我應該在cygwin中運行以下命令來處理符號鏈接。

git rm --cached -r . && git reset --hard 

git config --global alias.add-symlink '!__git_add_symlink(){ 
    dst=$(echo "$2")/../$(echo "$1"); 
    if [ -e "$dst" ]; then 
     hash=$(echo "$1" | git hash-object -w --stdin); 
     git update-index --add --cacheinfo 120000 "$hash" "$2"; 
     git checkout -- "$2"; 
    else 
     echo "ERROR: Target $dst does not exist!"; 
     echo "  Not creating invalid symlink."; 
    fi; 
    }; __git_add_symlink "$1" "$2"' 

git config --global alias.rm-symlink '!__git_rm_symlink(){ 
    git checkout -- "$1"; link=$(echo "$1"); 
    POS=$'\''/'\''; DOS=$'\''\\\\'\''; 
    doslink=${link//$POS/$DOS}; 
    dest=$(dirname "$link")/$(cat "$link"); 
    dosdest=${dest//$POS/$DOS}; 
    if [ -f "$dest" ]; then 
     rm -f "$link"; 
     cmd //C mklink //H "$doslink" "$dosdest"; 
    elif [ -d "$dest" ]; then 
     rm -f "$link"; 
     cmd //C mklink //J "$doslink" "$dosdest"; 
    else 
     echo "ERROR: Something went wrong when processing $1 . . ."; 
     echo "  $dest may not actually exist as a valid target."; 
    fi; 
    }; __git_rm_symlink "$1"' 

git config --global alias.rm-symlinks '!__git_rm_symlinks(){ 
    for symlink in `git ls-files -s | grep -E "^120000" | cut -f2`; 
    do 
     git rm-symlink "$symlink"; 
     git update-index --assume-unchanged "$symlink"; 
    done; 
    }; __git_rm_symlinks' 

git config --global alias.checkout-symlinks '!__git_checkout_symlinks(){ 
    POS=$'\''/'\''; DOS=$'\''\\\\'\''; 
    for symlink in `git ls-files -s | grep -E "^120000" | cut -f2`; 
    do 
     git update-index --no-assume-unchanged "$symlink"; 
     if [ -d "$symlink" ]; then 
      dossymlink=${symlink//$POS/$DOS}; 
      cmd //C rmdir //S //Q "$dossymlink"; 
     fi; 
     git checkout -- "$symlink"; 
     echo "Restored git symlink $symlink <<===>> `cat $symlink`"; 
    done; 
    }; __git_checkout_symlinks' 

git rm-symlinks 

我也嘗試過在SO的答案Git symlinks in Windows，這產生了相同的結果。

輸出：

運行上面的命令後，我得到的輸出是一個有點古怪，所以我不知道，如果劇本是成功的。

User@Computer /cygdrive/c/.../Local/devstack/edx-platform/edx-platform $./symlinks-fix.sh 
**Git checkout output** 
... 
Checking out files: 100% (6983/6983), done.

C:\Users\...\Local\devstack\edx-platform\edx-platform> 

爲什麼它會在最後進入Windows風格的命令提示符？這是我不確定git命令是否正常工作的地方。

在流浪：

運行vagrant up和vagrant ssh，運行paver devstack lms當我得到以下錯誤（類似於輸出paver devstack studio）後：

vagrant@precise64:~$ sudo su edxapp

據我瞭解，這是一個問題與符號鏈接（請參閱Google羣組上的this發佈）。

我是否正確運行上述符號鏈接腳本？如何檢查符號鏈接是否已成功處理？

其他嘗試：

繼谷歌組（以上鍊接）的建議，我也做了如下調整：

• 使用Vagrantfile設置VAGRANT_USE_VBOXFS =真
• 提供here
• 設置環境變量OPENEDX_RELEASE =「named-release/cypress」
• 從Vagrant實例安裝libxmlsec1。

後多vagrant destroy和vagrant provision的，我仍然有同樣的問題IOError: [Error 20] Not a directory。任何幫助將非常感激！

版本：

• Windows版本：8
• 流浪版本：1.7.4
• VirtualBox的版本：5.0。8
• openEdx發佈：命名發佈/柏

我認爲這個問題是由您cydrive路徑造成的錯誤。

嘗試在c:\cygwin\etc\fstab

none /cydrive cygdrive binary,posix=0,user 0 0

改變

none/cygdrive binary,posix=0,user 0 0

裁判：https://cygwin.com/cygwin-ug-net/using.html#cygdrive

UPDATE：

從CMD輸入「慶典」，然後複製/粘貼腳本的內容

如果你得到同樣的結果嘗試：

開放的.gitconfig（用記事本++或類似），如果加上這部分尚未現有

[alias] 
add-symlink = "!__git_add_symlink(){\n dst=$(echo \"$2\")/../$(echo \"$1\"); \n if [ -e \"$dst\" ]; then \n  hash=$(echo -n \"$1\" | git hash-object -w --stdin); \n  git update-index --add --cacheinfo 120000 \"$hash\" \"$2\"; \n  git checkout -- \"$2\"; \n else \n  echo \"ERROR: Target $dst does not exist!\"; \n  echo \"  Not creating invalid symlink.\"; \n fi; \n }; __git_add_symlink \"$1\" \"$2\"" 
rm-symlink = "!__git_rm_symlink(){\n git checkout -- \"$1\"; link=$(echo \"$1\"); \n POS=$'/'; DOS=$'\\\\\\\\'; \n doslink=${link//$POS/$DOS}; \n dest=$(dirname \"$link\")/$(cat \"$link\"); \n dosdest=${dest//$POS/$DOS}; \n if [ -f \"$dest\" ]; then \n  rm -f \"$link\"; \n  cmd //C mklink //H \"$doslink\" \"$dosdest\"; \n elif [ -d \"$dest\" ]; then \n  rm -f \"$link\"; \n  cmd //C mklink //J \"$doslink\" \"$dosdest\"; \n else \n  echo \"ERROR: Something went wrong when processing $1 . . .\"; \n  echo \"  $dest may not actually exist as a valid target.\"; \n fi; \n }; __git_rm_symlink \"$1\"" 
rm-symlinks = "!__git_rm_symlinks(){\n for symlink in `git ls-files -s | grep -E \"^120000\" | cut -f2`; \n do \n  git rm-symlink \"$symlink\"; \n  git update-index --assume-unchanged \"$symlink\"; \n done; \n }; __git_rm_symlinks" 
checkout-symlinks = "!__git_checkout_symlinks(){\n POS=$'/'; DOS=$'\\\\\\\\'; \n for symlink in `git ls-files -s | grep -E \"^120000\" | cut -f2`; \n do \n  git update-index --no-assume-unchanged \"$symlink\"; \n  if [ -d \"$symlink\" ]; then \n   dossymlink=${symlink//$POS/$DOS}; \n   cmd //C rmdir //S //Q \"$dossymlink\"; \n  fi; \n  git checkout -- \"$symlink\"; \n  echo \"Restored git symlink $symlink <<===>> `cat $symlink`\"; \n done; \n }; __git_checkout_symlinks" 

這將創建符號鏈接

一些Git命令

注：文件使用Unix行結尾，不使用Windows記事本編輯！

然後執行命令

git rm --cached -r . 
git reset --hard 
git rm-symlinks 

我在ENV測試，它的工作原理
