我无法使用PythonKit在Xcode 11中导入Python模块 [英] I can't import Python modules in Xcode 11 using PythonKit

问题描述

我现在正在使用Swift Package Manager.

I am now using Swift Package Manager.

使用它，我将PythonKit导入了我的Swift项目.

Using that, I imported PythonKit into my Swift project.

我现在无法使用PythonKit导入Python模块.

I can't import the Python modules using the PythonKit now.

它要求我设置PYTHON_LIBRARY路径，但我不知道该怎么做.

It asks me to set the PYTHON_LIBRARY path but I don't know how to do that.

有人可以帮助我吗?

import UIKit
import PythonKit

let sys = Python.import("sys")

class ViewController: UIViewController {

    @IBOutlet weak var netflixView: WKWebView!
    let netflixURL = URL(string: "https://www.netflix.com/login")

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.

        let pymsl = try Python.import(name: "pymsl")

        print("Python \(sys.version_info.major).\(sys.version_info.minor)")
        print("Python Version: \(sys.version)")
        print("Python Encoding: \(sys.getdefaultencoding().upper())")
    }
}

当我在iPhone上运行iOS应用时，这是错误消息

推荐答案

第一个SO答案，请原谅格式/等.我经历了一段时间，遇到了不同的错误，但总体上是相同的问题.希望这对您有所帮助-可以考虑一些资源:

First SO answer, so please forgive formatting / etc. I suffered through this for a while myself with different errors, but generally same issues. I hope this helps you -- a few resources to consider:

1) Pyto -适用于iOS/Catalyst的完全嵌入式Python环境；带有LXML和Python库移植说明<-在iOS上运行之后，您需要对此建模，我的解决方案适用于Mac Catalyst (预装有Python的Macs)

1) Pyto -- a fully embedded Python environment for iOS/Catalyst; with LXML and Python Library porting instructions <-- this is what you need to model after to run on iOS, my solution works for Mac Catalyst (Macs with Python preloaded)

2) Python套件教程-这个家伙一步一步地进行着，如何实现PythonKit

2) Python Kit Tutorial -- this guy goes through, step by step, how to implement PythonKit

这对我有用:

1)在签名和功能中禁用应用沙箱:

1) Disable App Sandbox in Signing and Capabilities:

在应用程序沙箱"右上角的签名和所有者"下功能中有一个"X"，请单击以删除应用程序沙箱"

2)在增强的运行时"的签名和功能"下:选中禁用库验证"

2) In "Hardened Runtime" under Signing and Capabilities: check "Disable Library Validation"

现在，我还没有按照这些规定向App Store提交应用，但是至少我的python文件和库可以加载/构建/运行！

Now, I haven't yet submitted an app to the App Store under these provisions, but at least my python files and libraries load / build / run!

UPDATE 05/15/2020:

UPDATE 05/15/2020:

对于Mac开发者发行版，您将必须对应用程序随附的所有.so或.dylib以及Python解释器和bin文件夹进行签名.开发完成后，我制作了一个快速的bash脚本来运行每个脚本.

For Mac Developer Distribution, you will have to sign all .so or .dylib's included with your app, along with the Python Interpreter and bin folder. I made a quick bash script to run through each one when done with dev.

function signThese() {
        find . -name "*.$1" | while read line; do
                codesign --force --verbose=4 --options=runtime --timestamp --sign "Developer ID Application: [INSERT YOUR CERT HERE]" $line
        done
}

这将允许您使用签名和功能"中的AppSandbox以及所有强化的运行时选项(如不禁用库验证一样).

This will allow you to use AppSandbox in Signing and Capabilities, and all Hardened Runtime Options (as in not disabling library validation).
