当 运行 纱线在 nixos 上时，elm-make 无法编译
elm-make fails to compile when running with yarn on nixos
我在 nixos 上与 yarn 合作的 elm 项目无法编译。这个项目为我使用 macOS 的同事编译成功；也许在我的机器上编译失败与我使用NixOS有关。
当我 运行 $ yarn start 我得到以下终端输出：
$ yarn start
yarn start v0.20.3
$ webpack-dev-server --env dev
env dev

看来问题可能与 elm-make 有关，因为这两个错误都出现了。我的路径在
找到 elm-make
$ which elm-make
/home/matthew/.nix-profile/bin/elm-make
与错误报告它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 在通过 ls 列出时确实存在：
$ 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 yarn start 输出中列出的命令时，除了在此节点模块路径中用 elm-make 替换 elm-make 外，我得到'No such file or directory' 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
当通过 ls 列出时可执行文件清晰可见时，为什么我在尝试 运行 此 'node-modules' elm-make 时会出现此 'No such file or directory' 错误？
是不是我的路径elm-make和'node-modules'下的路径位置不一样导致编译失败？也许纱线用错了。如果是这样，我如何设置 yarn 以使用正确的 elm-make?
如何才能 yarn start 成功编译项目？
非常感谢您的建议；我已经坚持了一段时间。
我建议您为 NixOS 选择安装 elm（以某种方式）。如果你创建一个每个人都使用的 shell.nix 并且完全避免通过 npm 依赖 nix，通常是最简单的。
elm-make 不存在的原因是 ELF 解释器，它位于 NixOS 的不同位置。
尝试ldd ./node_modules/elm/Elm-Platform/0.18.0/.cabal-sandbox/bin/elm-make
快速修复是将 ls -la $(nix-build -A elmPackages.elm '<nixpkgs>')/bin 中的所有二进制文件符号链接到您的 cabal 沙箱。
