Vagrant - paver devstack error: "[Errno 20] Not a directory"
Vagrant - paver devstack error: "[Errno 20] Not a directory"
我正在尝试通过 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 symlinks 引起的。
根据 Dealing with line endings and symlinks under Windows 下的 edx 故障排除指南，我应该 运行 在 cygwin 中使用以下命令来处理 symlinks。
git rm --cached -r . && git reset --hard
git config --global alias.add-symlink '!__git_add_symlink(){
dst=$(echo "")/../$(echo "");
if [ -e "$dst" ]; then
hash=$(echo "" | git hash-object -w --stdin);
git update-index --add --cacheinfo 120000 "$hash" "";
git checkout -- "";
else
echo "ERROR: Target $dst does not exist!";
echo " Not creating invalid symlink.";
fi;
}; __git_add_symlink "" ""'
git config --global alias.rm-symlink '!__git_rm_symlink(){
git checkout -- ""; link=$(echo "");
POS=$'\''/'\''; DOS=$'\''\\'\'';
doslink=${link//$POS/$DOS};
dest=$(dirname "$link")/$(cat "$link");
dosdest=${dest//$POS/$DOS};
if [ -f "$dest" ]; then
rm -f "$link";

git config --global alias.rm-symlinks '!__git_rm_symlinks(){

do
git rm-symlink "$symlink";
git update-index --assume-unchanged "$symlink";
done;

git config --global alias.checkout-symlinks '!__git_checkout_symlinks(){

git checkout -- "$symlink";

git rm-symlinks
我也尝试了 Git symlinks in Windows 的 SO 答案中的命令，结果相同。
输出：
我在 运行 执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。

为什么最后会进入Windows风格的命令提示符？这是我不确定 git 命令是否有效的地方。
在 Vagrant 中：
在 运行ning vagrant up 和 vagrant ssh 之后，当 运行ning paver devstack lms 时出现以下错误（paver devstack studio 的类似输出):

据我了解，这是 symlinks 的问题（请参阅 Google 组上的 this post）。
我 运行上面的 symlinks 脚本是否正确？如何检查 symlinks 是否已成功处理？
其他尝试：
根据google群里的建议（link上面），我也做了如下调整：
- 设置 VAGRANT_USE_VBOXFS = true
- 使用提供的 Vagrantfile here
- 设置环境变量OPENEDX_RELEASE="named-release/cypress"
- 正在从 Vagrant 实例安装 libxmlsec1。
多次vagrant destroy和vagrant provision之后，我仍然有同样的IOError: [Error 20] Not a directory问题。任何帮助将不胜感激！

我认为问题是你的cydrive路径不对造成的
尝试在c:\cygwin\etc\fstab
中改变
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 输入 'bash' 然后 copy/paste 脚本的内容
如果得到相同的结果，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）
