我在配置 Shadowsocks 配置文件時遇到了這個問題：

解決辦法是什麼？

編輯

有人比我在寫這篇文章時對原始碼有更好的了解，他設計了一個更新檔，該更新檔已送出給上游的 Guix。換句話說，這個問題可能很快就會得到解決。

查看 shadowsocks 的包定義，它似乎相當空，甚至沒有將 OpenSSL 列為輸入或任何類似的東西。此外，shadowsocks 似乎希望您將所有這些路徑保存在某種配置中。

config['crypto_path'] = {'openssl': config['libopenssl'],
                        'mbedtls': config['libmbedtls'],
                        'sodium': config['libsodium']}

這些技巧在傳統發行版（例如基於 Debian 等的發行版）上可能非常聰明，但是當與任何類型的功能包管理結合使用時，它們會被徹底破壞。處理此類問題的 Guix 方法是在建構時使用substitute*. 您的階段可能如下所示：

 (add-after 'unpack 'patch-crypto-paths
   (lambda* (#:key inputs #:allow-other-keys)
     (substitute* "shadowsocks/shell.py"
       (("config\\['libopenssl'\\]") 
        (string-append (assoc-ref inputs "openssl") "/path/to/libopenssl"))
       [...])
     #t))

$$ Since the above is obviously meant to be Guix code, you can freely use it under the GPLv3+, even though SO would normally mandate CC BY-SA. $$ 請注意，#t最近可能不再嚴格要求以結尾，但我認為您仍然會經常在 Guix 程式碼中找到它。
