混合编译过程的程序路径

问题描述 投票:0回答:1

从Brew转换为Elixir和Erlang的asdf版本控制工具后,我仍然无法编译我的旧项目:在编译过程中,它试图引用不存在的Brew的Cellar lib文件:

MacBook-Pro% mix test
==> gettext
Compiling 1 file (.erl)
/usr/local/Cellar/erlang/21.3.2/lib/erlang/lib/parsetools-2.1.8/include/yeccpre.hrl:59: illegal pattern
/usr/local/Cellar/erlang/21.3.2/lib/erlang/lib/parsetools-2.1.8/include/yeccpre.hrl:60: variable 'Error' is unbound
/usr/local/Cellar/erlang/21.3.2/lib/erlang/lib/parsetools-2.1.8/include/yeccpre.hrl:60: variable 'Stacktrace' is unbound
/usr/local/Cellar/erlang/21.3.2/lib/erlang/lib/parsetools-2.1.8/include/yeccpre.hrl:63: variable 'Stacktrace' unsafe in 'try' (line 60)
/usr/local/Cellar/erlang/21.3.2/lib/erlang/lib/parsetools-2.1.8/include/yeccpre.hrl:64: variable 'Error' unsafe in 'try' (line 60)
/usr/local/Cellar/erlang/21.3.2/lib/erlang/lib/parsetools-2.1.8/include/yeccpre.hrl:64: variable 'Stacktrace' unsafe in 'try' (line 60)
could not compile dependency :gettext, "mix compile" failed. You can recompile this dependency with "mix deps.compile gettext", update it with "mix deps.update gettext" or clean it with "mix deps.clean gettext"

即使没有任何/usr/local/Cellar/erlang文件夹

mix在哪里获取外部erlang库的路径以及如何更改它以使用asdf的bundle?

compilation erlang elixir mix

Erlang和Elixir使用$PATH环境变量中的二进制文件和库,如下所述:https://elixir-lang.org/install.html#installing-erlang

asdf通常在$PATH的末尾加载,这意味着如果你仍然通过brew安装了Erlang和Elixir,它将首先加载。也就是说,请仔细检查是否通过brew安装了任何其他Erlang版本。您可以使用命令brew uninstall erlang --force卸载所有版本

还可以使用以下命令在项目的根目录中设置本地Erlang和Elixir版本:

asdf local erlang 21.3.2
asdf local elixir 1.8.1-otp-21

根据您的环境更改版本。

最后使用命令asdf current检查asdf是否正在加载正确的版本。它应该显示如下:

elixir         1.8.1-otp-21 (set by /path/to/project/.tool-versions)
erlang         21.3.2   (set by /path/to/project/.tool-versions)
