我无法使用PythonKit在Xcode 11中导入Python模块

Question

我现在正在使用Swift Package Manager。

使用它，我将PythonKit导入了我的Swift项目。

我现在无法使用PythonKit导入Python模块。

它要求我设置PYTHON_LIBRARY路径，但我不知道该怎么做。

谁能帮我？

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

Answer 1

第一个SO答案，所以请原谅格式/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。我希望这对您有帮助-需要考虑的一些资源：

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
<-这是在iOS上运行后需要建模的东西，我的解决方案适用于Mac
Catalyst （预装了Python的Mac）

2）Python Kit教程
-这个人一步一步地介绍了如何实现PythonKit

这对我有用：

1）在签名和功能中禁用应用沙箱：

在“应用程序沙箱”的右上角的“签名和功能”下，有一个“
X”，单击以删除该应用程序沙箱

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

Validation

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:

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
}

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