PhantomJS 安装

PhantomJS 安装

Mac OS X && Windows

一、PhantomJS下载地址

按照系统下载对应的版本，

macOS 下载： phantomjs-2.1.1-macosx.zip

Windows下载：phantomjs-2.1.1-windows.zip

并解压到用户目录下面，

macOS 解压路径：

/User/xxx/phantomjs-2.1.1-macosx

Windows 解压路径：

D:\phantomjs-2.1.1-windows ，并重命名为 D:\phantomjs

二、PhantomJS不须要安装，解压便可使用

Windows PATH变量

在“系统变量”选项区域中查看PATH变量，若是不存在，则新建变量 PATH，

不然选中该变量，单击“编辑”按钮，在“变量值”文本框的起始位置添加 

D:\phantomjs\bin，开始-运行-输入cmd，输入 phantomjs --version， 
 
若是能够看到版本号，则安装成功。

macOS PATH变量

若是用户目录下存在 .bash_profile ，好比个人/User/xxx/.bash_profile，则添加一行 

export PATH="$PATH:/Users/xxx/phantomjs-2.1.1-macosx/bin"

不然新建 .bash_profile,而后在添加上文

在terminal中输入

phantomjs --version

若是能够看到版本号，则安装成功。

三、使用npm安装的时候如何环境变量中没有phantomjs，就会从github下载安装phantomjs，可是你懂的?，大多数状况下会超时，即便把npm的镜像改为淘宝的仍是同样的结果

• 而后聪明的你想到可使用 npm install -g phantomjs , 但是现实告诉你

Considering PhantomJS found at /usr/local/bin/phantomjs
Looks like an `npm install -g`

• 又回到了原点，是否是npm的问题？我用cnpm试一下看看

• 而后聪明的你想到可使用 cnpm install -g phantomjs，现实是这样

• 看到提示

• 什么鬼？不陪你玩了

sudo npm uninstall -g phantomjs

sudo cnpm uninstall -g phantomjs

sudo rm -rf /usr/local/lib/node_modules/phantomjs

• 而后你又想到可使用HomeBrew安装

brew install phantomjs

• ok,安装完成，打开terminal，输入 phantomjs --version，能够看到版本号，一块儿正常，能够愉快的玩耍了，而后你又愉快的开始 npm install 了，而后你又发现 使用phantomjs的项目里面 could not verify phantomjs,而后

总结

一、可使用cnpm install 安装使用phantomjs的项目的node_modules，cnpm 会 使用phantomjs-prebuilt代替phantomjs，而且不中途翻车

二、下载安装phantomjs，并配置环境变量，这样无论是cnpm install仍是npm install均可以使用phantomjs，并且在pycharm里面也不会报找不到phantomjs的错误
