在我正在工作的存儲庫中最近發生更改後，我無法再構建。當試圖運行任何stack命令，如stack build，我得到以下錯誤：'在路徑上找不到名爲git的可執行文件：'在運行堆棧時
$ stack build

看來，我的stack程序不知道正確的路徑，我git程序。
如何指定我的git路徑爲stack？
我已驗證我的git安裝在以下路徑中。
$ which git
/nix/var/nix/profiles/default/bin/git
我在nixos 17.03上。
編輯。
我確定stack build和which git命令運行在相同的環境中，因爲它們在同一個shell中重新運行。
我的路徑是
$ echo $PATH
/home/matthew/bin:/run/wrappers/bin:/run/wrappers/bin:/home/matthew/.nix-profile/bin:/home/matthew/.nix-profile/sbin:/home/matthew/.nix-profile/lib/kde4/libexec:/nix/var/nix/profiles/default/bin:/nix/var/nix/profiles/default/sbin:/nix/var/nix/profiles/default/lib/kde4/libexec:/run/current-system/sw/bin:/run/current-system/sw/sbin:/run/current-system/sw/lib/kde4/libexec
這表明/nix/var/nix/profiles/default/bin是路徑，其中包含git。
而且，在我stack.yaml文件時，我設置system-ghc: true我得到一個「訪問權限」錯誤而不是錯誤的「未找到可執行文件名爲混帳」。
$ stack build

堆棧只是增加了路徑。 '/ nix/var/nix/profiles/default/bin /'似乎不在PATH上 - 它不在列表中。你確定堆棧正在與其相同的環境中運行嗎？可能有助於做'echo $ PATH'來確定，看看它如何偏離堆棧正在使用的PATH。 – mgsloan
@mgsloan感謝您的評論。我已經按照建議編輯了包含'echo $ PATH'結果的問題。另外我發現，當在我的'stack.yaml'文件中啓用'system-ghc'時（如編輯中所述），我得到'訪問權限'錯誤，而不是'找不到'錯誤。 – mherzl
我沒有線索，似乎事情的工作方式與您的設置非常不一致。設置system-ghc對於查找git二進制文件不應有任何區別。 – mgsloan
