Question

在虚拟环境中设置clj-python时遇到以下错误。

为了解决该错误，我做了两个步骤，但错误仍然存在。

使用“ py /初始化！”来指定“ ：python-executable ”和“ ：library-path ”（请参阅来源“ core.clj：
如果我在virtualenv的lib“〜/ .venv / ml / lib / libpython3.7m.dylib”目录中进行了符号链接，则无法启动“ lein repl”。
例如ln -s /usr/local/Cellar/python/3.7.7/Frameworks/Python.framework/Versions/3.7/lib/libpython3.7m.dylib

请随时发表评论。

2020年5月24日更新

将本地字典中的“：python-executable” 和“：python-executable” 撤消时，可以启动

“ lein repl” 。

(ns my-stuff.core
  (:require [libpython-clj.python :as py]))

(py/initialize! :python-executable "/usr/local/Cellar/python/3.7.7/Frameworks/Python.framework/Versions/3.7/bin/python3.7"
                :library-path "/usr/local/Cellar/python/3.7.7/Frameworks/Python.framework/Versions/3.7/lib/libpython3.7m.dylib")

(require '[libpython-clj.require :refer [require-python]])

错误

不久前，我对clj-python进行了一次小测试，并且lein似乎存在局限性，因此鼓励新项目使用clj工具和deps.edn。

我有一个使用virtualenv的小示例，其中包括Clojure / Python互操作以及一个小型库，您可以在以下虚拟环境中从pip安装：https://github.com/dfuenzalida/clj-python-interop
