The error does gives us some hint on whats wrong happening as follows :

FileNotFoundError: [Errno 2] No such file or directory: 'C:\\Users\\Mike\\AppData\\Local\\Programs\\Python\\Python36-32\\lib\\site-packages\\selenium\\webdriver\\remote\\getAttribute.js'

Which essentially means getAttribute.js wasn't found in it's intended location.

getAttribute.js

getAttribute.js file internally works with the errors and other critical JavaScript functions as below :

element not selectable
element not visible
invalid cookie domain
invalid element coordinates
invalid element state
invalid selector
invalid selector
parseInt()
push()
indexOf()
toUpperCase()
execScript()
etc

A typical getAttribute.js file looks like :

function(){return function(){var d=this;function f(a){return"string"==typeof a};function h(a,b){this.code=a;this.a=l[a]||m;this.message=b||"";a=this.a.replace(/((?:^|\s+)[a-z])/g,function(a){return a.toUpperCase().replace(/^[\s\xa0]+/g,"")});b=a.length-5;if(0>b||a.indexOf("Error",b)!=b)a+="Error";this.name=a;a=Error(this.message);a.name=this.name;this.stack=a.stack||""}
(function(){var a=Error;function b(){}b.prototype=a.prototype;h.b=a.prototype;h.prototype=new b;h.prototype.constructor=h;h.a=function(b,c,g){for(var e=Array(arguments.length-2),k=2;kparseFloat(D)){C=String(F);break a}}C=D}var G;var H=d.document;G=H&&y?B()||("CSS1Compat"==H.compatMode?parseInt(C,10):5):void 0;var ba=r("Firefox"),ca=v()||r("iPod"),da=r("iPad"),I=r("Android")&&!(w()||r("Firefox")||r("Opera")||r("Silk")),ea=w(),J=r("Safari")&&!(w()||r("Coast")||r("Opera")||r("Edge")||r("Silk")||r("Android"))&&!(v()||r("iPad")||r("iPod"));function K(a){return(a=a.exec(n))?a[1]:""}(function(){if(ba)return K(/Firefox\/([0-9.]+)/);if(y||z||x)return C;if(ea)return v()||r("iPad")||r("iPod")?K(/CriOS\/([0-9.]+)/):K(/Chrome\/([0-9.]+)/);if(J&&!(v()||r("iPad")||r("iPod")))return K(/Version\/([0-9.]+)/);if(ca||da){var a=/Version\/(\S+).*Mobile\/(\S+)/.exec(n);if(a)return a[1]+"."+a[2]}else if(I)return(a=K(/Android\s+([0-9.]+)/))?a:K(/Version\/([0-9.]+)/);return""})();var L,M=function(){if(!A)return!1;var a=d.Components;if(!a)return!1;try{if(!a.classes)return!1}catch(g){return!1}var b=a.classes,a=a.interfaces,e=b["@mozilla.org/xpcom/version-comparator;1"].getService(a.nsIVersionComparator),c=b["@mozilla.org/xre/app-info;1"].getService(a.nsIXULAppInfo).version;L=function(a){e.compare(c,""+a)};return!0}(),N=y&&!(8<=Number(G)),fa=y&&!(9<=Number(G));I&&M&&L(2.3);I&&M&&L(4);J&&M&&L(6);var ga={SCRIPT:1,STYLE:1,HEAD:1,IFRAME:1,OBJECT:1},O={IMG:" ",BR:"\n"};function P(a,b,e){if(!(a.nodeName in ga))if(3==a.nodeType)e?b.push(String(a.nodeValue).replace(/(\r\n|\r|\n)/g,"")):b.push(a.nodeValue);else if(a.nodeName in O)b.push(O[a.nodeName]);else for(a=a.firstChild;a;)P(a,b,e),a=a.nextSibling};function Q(a,b){b=b.toLowerCase();return"style"==b?ha(a.style.cssText):N&&"value"==b&&R(a,"INPUT")?a.value:fa&&!0===a[b]?String(a.getAttribute(b)):(a=a.getAttributeNode(b))&&a.specified?a.value:null}var ia=/[;]+(?=(?:(?:[^"]*"){2})*[^"]*$)(?=(?:(?:[^']*'){2})*[^']*$)(?=(?:[^()]*\([^()]*\))*[^()]*$)/;
function ha(a){var b=[];t(a.split(ia),function(a){var c=a.indexOf(":");0



Error Reason :

Incase the getAttribute.js file doesn't gets downloaded properly Selenium and webdriver modules may not work properly. The issue can arise if the Selenium Client encounters any error during its transmission or storage.

Selenium Team is currently working on the issue SeleniumHQ/selenium/5378 to generate the binary checksum of the Downloaded Selenium Client which will help you to avoid encountering errors which may have been introduced during its transmission or storage.

Solution

Till then a solution will be to :


Check if Python is properly installed

C:\Users\username>python
Python 3.9.0 (v3.9.0:69c0db5, Jan 31 2018, 17:54:52) [MSC v.1900 32 bit (Intel)]
 on win32
Type "help", "copyright", "credits" or "license" for more information.
>>>
