macos - 为什么curl(由 Homebrew 程序启动)在.nix-profile中查找？

Question

不久前我安装了 nix，但我已将其删除，但是现在当我尝试安装 threadscope 时，出现以下错误:

Henriks-MBP:trial henke$ brew install homebrew/gui/Threadscope
==> Installing threadscope from homebrew/gui
==> Installing dependencies for homebrew/gui/threadscope: libpng, freetype, fontconfig, pixman, gettext, libffi, glib, cairo, ghc, jpeg, libtiff, gobject-introspection, gdk-p

现在为什么 homebrew 试图在 .nix-profile 中查找内容以及我该如何安装 threadscopes 依赖项？

Answer 1

这不是专门研究 .nix-profile 目录的 Homebrew 程序。这是安装 nix 的片段。

当您安装 nix 时，它安装了自己的 CA 证书。检查SSL_CERT_FILE 的值。就我而言:

$ echo $SSL_CERT_FILE
/Users/my-user/.nix-profile/etc/ssl/certs/ca-bundle.crt

在尝试将 curl 与 https 一起使用时，我遇到了此证书的问题，这就是 homebrew 正在做的事情。

我假设您最近刚刚删除了 nix 并且仍然在 shell 中设置了该变量。如果您只是关闭所有当前打开的 shell 并打开全新的 shell，则应该修复此问题。

您还可以尝试在任何打开的 shell 中取消设置 SSL_CERT_FILE，而不是全部关闭/打开它们。
