我在运行＆＃34; python3＆＃34;时遇到问题命令以及＆＃34; pip3＆＃34;安装几个python模块。看起来我的pip3链接到python 3.6（这是我想要使用的），但是python3链接到3.5。见下文：
pip3 --version
pip 9.0.1 from /usr/local/lib/python3.6/site-packages (python 3.6)
python3 --version
Python 3.5.2
我想运行python3.6，我想我的PATH变量可能不正确（或者那种程度上的东西）。感谢

像这样配置<style>
.w3-left, .w3-right, .w3-badge {cursor:pointer}
.w3-badge {height:13px;width:13px;padding:0}
.mySlides {
border: none;
opacity: 0;
position: absolute;
-webkit-transition: opacity 2s linear;
-moz-transition: opacity 2s linear;
-o-transition: opacity 2s linear;
transition: opacity 2s linear;
}
.showMe {opacity: 1;}
</style>
<div class="w3-content w3-display-container" style="max-width:800px">
<img id="slideimg0" class="mySlides showMe" src="img_nature_wide.jpg" style="width:100%">
<img id="slideimg1" class="mySlides" src="img_fjords_wide.jpg" style="width:100%">
<img id="slideimg2" class="mySlides" src="img_mountains_wide.jpg" style="width:100%">
<div class="w3-center w3-section w3-large w3-text-white w3-display-bottommiddle" style="width:100%">
<span class="w3-badge demo w3-border w3-transparent w3-hover-white" onclick="currentDiv(1)"></span>

<span class="w3-badge demo w3-border w3-transparent w3-hover-white" onclick="currentDiv(3)"></span>
</div>
</div>
<script>
var slideIndex = 1;
showDivs(slideIndex);

function showDivs(n) {

if (n > x.length) {slideIndex = 1}
if (n < 1) {slideIndex = x.length}

dots[i].className = dots[i].className.replace(" w3-white", "");
}
x[slideIndex-1].style.display = "block";

}
var timer = setInterval(nextImage, 4000);
var curImage = 0;
var numImages = 3;
function nextImage() {

function addClass(elem, name) {
var c = elem.className;
if (c) c += " ";
c += name;
elem.className = c;
}
function removeClass(elem, name) {
var c = elem.className;
elem.className = c.replace(name, "").replace(/\s+/g, " ").replace(/^\s+|\s+$/g, "");
}
</script>
.bash_profile
//为Python 3.6设置PATH
//原始版本保存在.bash_profile.pysave
中 alias python3='python3.6'
PATH="/Library/Frameworks/Python.framework/Versions/3.6/bin:${PATH}"
