在nixos上运行纱线时，elm make无法编译

我正在处理的

elm

项目

warn

on

nixos

无法编译。该项目为使用macOS的同事成功编译；在我的机器上编译失败可能与我使用NixOS有关

当我运行

$warn start

时，我得到以下终端输出：

$ yarn start
yarn start v0.20.3
$ webpack-dev-server --env dev 
env dev
Project is running at http://0.0.0.0:3000/

Content not from webpack is served from /home/matthew/backup/azara_work/platform/web/src

Running elm-make /home/matthew/backup/azara_work/platform/web/src/App.elm --yes --warn --debug --output /tmp/117814-7766-1wq3nh5.xanii6yldi.js

当我尝试在

http://0.0.0.0:3000/

my browser console显示以下错误：

与错误报告试图查找的路径不同的位置

elm make

（

/home/matthew/backup/azara_work/platform/web/node_modules/elm/elm platform/0.18.0/.cabal sandbox/bin/elm make

）。我想知道这是否与问题有关

在错误中列出的目录中，

elm make

通过

ls

列出时确实出现：

$ ls /home/matthew/backup/azara_work/platform/web/node_modules/elm/Elm-Platform/0.18.0/.cabal-sandbox/bin/
elm  elm-make  elm-package  elm-reactor  elm-repl

但是，当我尝试运行

warn start

的输出中列出的命令时，除了在该节点模块路径中将

elm make

替换为elm make之外，我得到一个“无此类文件或目录”错误

$ ./node_modules/elm/Elm-Platform/0.18.0/.cabal-sandbox/bin/elm-make /home/matthew/backup/azara_work/platform/web/src/App.elm --yes --warn --debug --output /tmp/117814-7422-1p5ad15.q2uqqzd7vi.js
-bash: ./node_modules/elm/Elm-Platform/0.18.0/.cabal-sandbox/bin/elm-make: No such file or directory

当可执行文件通过

ls

列出时清晰可见时，为什么在尝试运行此“节点模块”

elm make

时会出现“无此类文件或目录”错误

编译失败是因为我的路径的

elm make

和“节点模块”下的另一个路径位置不同吗？也许纱线用错了。如果是这样，我如何设置纱线以使用正确的

elm make

如何让

纱线开始

成功编译项目

建议是非常感谢的；我已经在这个问题上纠缠了一段时间。

我建议您为NixOS选择elm安装。通常最简单的方法是创建人人都使用的shell.nix，并避免通过npm依赖nix

elm make之所以不存在，是因为ELF解释器对于NixOS来说位于不同的位置

尝试

ldd./node\u modules/elm/elm Platform/0.18.0/.cabal sandbox/bin/elm make

---

快速修复方法是将

ls-la$（nix build-A elmPackages.elm''中的所有二进制文件进行符号链接/bin

到你的阴谋集团沙箱。

创建一个符号链接

$ln-s/home/matthew/.nix profile/bin/elm make

从沙箱bin内部

/home/matthew/backup/azara_work/platform/web/node_modules/elm/elm/0.18.0/.cabal sandbox/bin

起作用。非常感谢。

$ ls /home/matthew/backup/azara_work/platform/web/node_modules/elm/Elm-Platform/0.18.0/.cabal-sandbox/bin/
elm  elm-make  elm-package  elm-reactor  elm-repl

$ ./node_modules/elm/Elm-Platform/0.18.0/.cabal-sandbox/bin/elm-make /home/matthew/backup/azara_work/platform/web/src/App.elm --yes --warn --debug --output /tmp/117814-7422-1p5ad15.q2uqqzd7vi.js
-bash: ./node_modules/elm/Elm-Platform/0.18.0/.cabal-sandbox/bin/elm-make: No such file or directory
