Question

我正在尝试集成两个框架，并且正在安装这两个框架的需求，但是似乎两个框架中都使用了库“ Crypto”，并且具有不同的使用版本，所以如果我安装一个框架的需求的框架，它返回我的第一个错误：

exception in thread Thread-1:
Traceback (most recent call last):

 File "/home/ubuntu/.local/lib/python3.6/site-packages/cryptoconditions/crypto.py", line 15, in encode
return base58.b58encode(data).encode()
AttributeError: 'bytes' object has no attribute 'encode'

以及框架的第二个要求，它还向我返回了其他错误：

<button id="btn_change">OK</button>
<br>
<p id="content"></p>

<script>

(function() {
   var httpRequest;
   //Set an event listener on your button
   document.getElementById("btn_change").addEventListener('click', makeRequest);

   function makeRequest() {
      httpRequest = new XMLHttpRequest();

      if (!httpRequest) {
          alert('Giving up :( Cannot create an XMLHTTP instance');
          return false;
      }

      httpRequest.onreadystatechange = setContents;
      //Open then send the request to your page
      httpRequest.open('GET', 'myText1.txt');
      httpRequest.send();
   }

   function setContents() {
     if (httpRequest.readyState === XMLHttpRequest.DONE) {
       if (httpRequest.status === 200) {
        //Set the contents of your p tag
         document.getElementById("content").innerHTML = httpRequest.responseText;
       } else {
         alert('There was a problem with the request.');
       }
    }
 }
})();    
</script>    
</body>

有什么想法可以避免吗？

好像cryptoconditions库做错了。

您应该提交一个错误，要求更新所需的base58版本并查看对其的所有调用。 Python3的通常行为是在bytes上返回some_encoder_library.encode()，在str上返回some_encoder_library.decode()。 base58模块的新版本遵循此规则，尽管base58编码的对象当然绝不包含任何特殊符号。 cryptoconditions仍在使用先前版本，其中b58encode返回str。

同时，您可以对已安装的库进行本地修改，也可以对其进行本地修改，然后安装fork。从this line删除encode()呼叫后，一切可能都可以正常工作。

Python库“加密”冲突
