python - pip 不工作，引用/private/var 路径失败

Question

使用Python多年我还没有见过这个。当我尝试 pip install 时，它提示 /private/var。这是权限问题吗？

location-tools 是我尝试安装的 python 包的名称。我在虚拟环境中，但在虚拟环境之外却遇到了完全相同的错误。

    pip install .                                                                                                                             1   master

Answer 1

正如评论中提到的，这是您的 setup.py 中的错误。根据错误消息，setup.py 脚本似乎正在尝试访问 ll_plot 可执行文件。由于它说它不存在，因此您可能有一个入口 pip 脚本(通过 setuptools)或者正在尝试访问与 setup.py 或其他构建脚本相关的二进制可执行文件。

您需要检查所有脚本的 shebang，以确保它们没有尝试使用不存在的环境。当然，如果这是一个公共(public)包(或不是)，您需要确保记录构建先决条件以及需要如何配置环境才能正确构建包。
