如何在本地使用dialyxir？

Question

我dialyxir在phoenix项目下的mix.exs文件中有：

{:dialyxir, "~> 0.5", only: [:dev, :test], runtime: false}

但是在mix dialyzer项目路径下运行时出现此错误：

$ mix dialyzer

我也尝试按照官方网站再次安装：

mix do deps.get, deps.compile

但是，我得到了同样的结果。有什么问题？

似乎您有一些文件问题： _build/.mix/dialyxir_erlang-19.3.plt 不可写该文件不可写。您可以手动测试触摸此目录中的文件并修改它吗？
