如何告訴 pip 在哪里可以找到安裝軟件包所需的依賴項？ 包是pybgpstream，依賴是bgpstream

Question

我想使用 bgpstream。 我安裝了它。 我在命令行中使用 BGPReader 對其進行測試，一切似乎都正常工作。

現在我想安裝 pybgpstream 以在我的 python 腳本中使用該工具。 要安裝 pybgpstream，您首先必須安裝 bgpstream。 如上所述，它已經安裝。

這是我嘗試安裝時發生的情況：

$ pip3 install pybgpstream

事實上它告訴我他找不到“libbgpstream 2.0.0”。 它實際上在 /usr/local/lib 中，稱為 libbgpstream.so.2.0.0 ！

我已經像在https://bgpstream.caida.org/docs/install/pybgpstream說的那樣：

LD_LIBRARY_PATH=/usr/local/lib/libbgpstream.so.2.0.0

感謝您的閱讀。 你可以幫幫我嗎 ？

我終於將我的操作系統（ubuntu 18.04）更改為 kali linux 以獲得全新的操作系統。 現在一切正常。
