Vagrant - paver devstack错误:"[Errno 20]不是目录"

Question

我试图用Vagrant安装edx Devstack,我在Windows机器上.我收到的错误似乎是由Windows不支持的符号链接引起的.

根据Windows下处理行结尾和符号链接下的edx故障排除指南,我应该在cygwin中运行以下命令来处理符号链接.

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

我也尝试过在Windows中对Git符号链接的回答中的命令,这会产生相同的结果.

输出:

运行上述命令后得到的输出有点奇怪,所以我不确定脚本是否成功.

User@Computer /cygdrive/c/.../Local/devstack/edx-platform/edx-platform $./symlinks-fix.sh
**Git checkout output**

为什么最后会进入Windows风格的命令提示符？这是我不确定git命令是否正常工作的地方.

在Vagrant中:

运行后vagrant up和vagrant ssh我运行的时候遇到下面的错误paver devstack lms(类似的输出paver devstack studio):

根据我的理解,这是符号链接的问题(请参阅Google小组上的这篇文章).

我正确运行上面的符号链接脚本吗？如何检查符号链接是否已成功处理？

其他尝试:

根据谷歌小组中的建议(上面的链接),我也做了以下调整:

• 设置VAGRANT_USE_VBOXFS = true
• 使用Vagrantfile提供这里
• 设置环境变量OPENEDX_RELEASE ="named-release/cypress"
• 从Vagrant实例安装libxmlsec1.

经过多次vagrant destroy和vagrant provision的,我仍然有同样IOError: [Error 20] Not a directory的问题.任何帮助将非常感激!

版本:

• Windows版本:8
• Vagrant版本:1.7.4
• VirtualBox版本:5.0.8
• openEdx发布:named-release/cypress

我认为这个问题是由于你的cydrive路径错误引起的。

尝试改变c:\cygwin\etc\fstab

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

到

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

参考文献：https ://cygwin.com/cygwin-ug-net/using.html#cygdrive

更新：

在 CMD 中输入“bash”，然后复制/粘贴脚本的内容

如果您得到相同的结果，请尝试：

打开 .gitconfig（使用 Notepad++ 或类似工具）并添加此部分（如果尚不存在）

[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"

这将为符号链接创建一些 git 命令

注意：文件使用 Unix 行结尾，请勿使用 Windows 记事本编辑！

然后执行命令

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

我在我的环境中测试了它并且它有效
