流浪者 - 摊铺机开发堆栈错误："[Errno 20] Not a directory"

Question

我正在尝试使用Vagrant安装edx Devstack，并且我在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

我还在Windows中尝试了SO answer to Git符号链接中的命令，这会产生相同的结果。

输出：

运行以上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**

为什么它最后会进入Windows风格的命令提示符？这就是我不确定git命令是否有效的地方。

在流浪者：

运行vagrant up和vagrant ssh后，在运行paver devstack lms时出现以下错误（类似于paver devstack studio的输出）：

vagrant@precise64:~$ sudo su edxapp

据我所知，这是符号链接的问题（请参阅谷歌群组上的这篇文章）。

我是否正确运行了上面的符号链接脚本？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
• 使用此处提供的Vagrantfile
• 设置环境变量OPENEX_RELEASE="named RELEASE/cypris"
• 从Vagrant实例安装libxmlsec1

经过多次vagrant destroy和vagrant provision，我仍然有相同的IOError: [Error 20] Not a directory问题。任何帮助都将不胜感激！

版本：

• Windows版本：8
• 含糊版本：1.7.4
• VirtualBox版本：5.0.8
• openEdx发布：命名发布/柏树

我认为问题是由您的cydrive路径错误引起的。

尝试更改c:cygwinetcfstab

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

至

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

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

更新：

从CMD键入"bash"，然后复制/粘贴脚本的内容

如果你得到相同的结果，尝试：

打开.gitconfig（使用Notepad++或类似功能），如果它还不存在，则添加此部分

[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行尾，不要使用windows记事本进行编辑

然后执行命令

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

我在我的env中测试了它，它可以在中运行
