Question

前段时间我安装了nix，但我已将其删除，但是现在当我尝试安装threadscope时，我得到了以下错误：

Henriks-MBP:trial henke$ brew install homebrew/gui/Threadscope

现在为什么自制软件试图在.nix-profile中查找内容以及如何安装线程范围依赖项呢？

Answer 1

这不是专门研究.nix-profile目录的自制软件。这是安装nix的片段。

安装nix后，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

尝试将curl与https一起使用时，我遇到了此证书的问题，这就是自制软件正在做的事情。

我假设您刚刚删除了nix并且仍然在shell中设置了该变量。如果你只是关闭任何当前打开的shell并打开全新的shell，这应该是固定的。

你也可以在任何打开的shell中尝试unset SSL_CERT_FILE，而不是关闭/打开它们。

为什么curl（由自制软件推出）查找.nix-profile？
