[BUG] The filename, directory name, or volume label syntax is incorrect.

[keiqiu]

in windows 10 system:
workdir: d://work_golang
git clone https://github.com/micro/services.git

micro run services/helloworld
mkdir C:\Users\user\AppData\Local\Temp\micro\uploads\helloworld\D:: The filename, directory name, or volume label syntax is incorrect.

when i change the code runtime/default.go:133

target = filepath.Join(dst, header.Name)
// if no join is needed, replace with ToSlash:
// target = filepath.ToSlash(header.Name)

to

target = filepath.Join(dst, header.Name)
// if no join is needed, replace with ToSlash:
target = filepath.ToSlash(header.Name)

it will be ok

这个问题现在官方还没解决吗？ 现在运行还报这个错误。

在windows上修改了default.go那两行后还是会报错，linux上直接上运行就可以了
