【erlang】rebar3创建、编译报错：badarg

先上结论，有两种可能：

1. git的user.name使用了中文

通过git config use.name ‘myname’ 改成英文

2. 没有以管理员身份运行命令行工具

详情

在使用rebar3的时候，无论是编译还是创建erlang项目，都会有提示错误，说是有非法的参数

rebar3 new app myapp
......
===> Uncaught error in rebar_core. Run with DEBUG=1 to see stacktrace or consult rebar3.crashdump
===> Uncaught error: badarg

但是查看rebar3.crashdump，发现错误信息只有下边这两行

//rebar3.crashdump
Error: badarg
[]

后边查询资料，发现没有和我相同问题的，判断应该是我这边配置的问题。加上debug=1后执行，发现中间有很多获取本地git的use.name use.email配置的信息，然后我查看这两个配置，发现user.name是中文，怀疑是编码的问题，修改后果然好了。
