背景

go项目，使用glide install命令去下载安装依赖，依赖中有个github.com/hashicorp/consul

问题描述

一直无法下载安装依赖成功，报错如下：

[ERROR] Export failed for github.com/hashicorp/consul: Unable to export source: exit status 128
[ERROR] Unable to export dependencies to vendor directory: Unable to export source: exit status 128

解决思路

先日了狗表达心情！

一顿google，发现提供的思路都差不多为：

glide cc

rm -rf vendor

尝试了无数次后都是失败了

在google的过程中，有的人建议贴出debug日志，无奈最后就自己加上了debug日志，得到了如下

具体日志

[ERROR] Export failed for github.com/hashicorp/consul: Unable to export source: exit status 128

[DEBUG] Output was: error: unable to create file C:\\\Users\\\M\\\AppData\\\Local\\\Temp\\\glide-vendor249536483\\\vendor\\\github.com\\\hashicorp\\\consul\\\vendor/github.com/hashicorp/go-discover/provider/azure/vendor/github.com/Azure/azure-sdk-for-go/services/network/mgmt/2015-06-15/network/expressroutecircuitauthorizations.go: Filename too long[DEBUG]

Unlocking https-github.com-hashicorp-consul

[ERROR] Unable to export dependencies to vendor directory: Unable to export source: exit status 128

[DEBUG] Output was: error: unable to create file C:\\\Users\\\M\\\AppData\\\Local\\\Temp\\\glide-vendor249536483\\\vendor\\\github.com\\\hashicorp\\\consul\\\vendor/github.com/hashicorp/go-discover/provider/azure/vendor/github.com/Azure/azure-sdk-for-go/services/network/mgmt/2015-06-15/network/expressroutecircuitauthorizations.go: Filename too long

日了狗，看描述大概明白了，glide在执行新建文件的时候发现文件名过长了！！！

解决办法

那么问题就演变成了glide error filename too long的问题了

具体方法：

Enable long paths on Windows (requires Windows 10 Anniversary Update or newer): https://superuser.com/a/1119980/97078

Configure git to use long paths: git config --global core.longpaths true (globally) or git config core.longpaths true (per project)

我执行了第二步就解决了问题，那么大概就是glide 会去使用git去拉取代码和创建文件了的

小结

还是问题的官方日志靠谱，遇到问题先获取更多的日志吧
