摘要：變量如果用戶目錄下存在，比如我的，則添加一行否則新建然后在添加上文在中輸入如果可以看到版本號，則安裝成功。

1、PhantomJS下載地址

按照系統(tǒng)下載對應(yīng)的版本，

macOS 下載： phantomjs-2.1.1-macosx.zip

Windows下載：phantomjs-2.1.1-windows.zip

并解壓到用戶目錄下面，

macOS 解壓路徑：

/User/xxx/phantomjs-2.1.1-macosx

Windows 解壓路徑：

D:phantomjs-2.1.1-windows ，并重命名為 D:phantomjs

2、PhantomJS不需要安裝，解壓即可使用

在“系統(tǒng)變量”選項(xiàng)區(qū)域中查看PATH變量，如果不存在，則新建變量 PATH，

否則選中該變量，單擊“編輯”按鈕，在“變量值”文本框的起始位置添加 

D:phantomjsin，開始-運(yùn)行-輸入cmd，輸入 phantomjs --version， 
 
如果可以看到版本號，則安裝成功。

如果用戶目錄下存在 .bash_profile ，比如我的/User/xxx/.bash_profile，則添加一行 

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

否則新建 .bash_profile,然后在添加上文

在terminal中輸入

phantomjs --version

如果可以看到版本號，則安裝成功。

3、使用npm安裝的時(shí)候如何環(huán)境變量中沒有phantomjs，就會(huì)從github下載安裝phantomjs，但是你懂的?，大多數(shù)情況下會(huì)超時(shí)，即使把npm的鏡像改成淘寶的還是一樣的結(jié)果

Saving to /var/folders/hn/55rkvgy97797tgx6cld83zl80000gn/T/phantomjs/phantomjs-2.1.1-macosx.zip

然后聰明的你想到可以使用 npm install -g phantomjs , 可是現(xiàn)實(shí)告訴你

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

又回到了原點(diǎn)，是不是npm的問題？我用cnpm試一下看看

然后聰明的你想到可以使用 cnpm install -g phantomjs，現(xiàn)實(shí)是這樣

看到提示

Install fail! Error: post install error, please remove node_modules before retry!

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

然后你又想到可以使用HomeBrew安裝

brew install phantomjs

ok,安裝完成，打開terminal，輸入 phantomjs --version，可以看到版本號，一起正常，可以愉快的玩耍了，然后你又愉快的開始 npm install 了，然后你又發(fā)現(xiàn) 使用phantomjs的項(xiàng)目里面 could not verify phantomjs,然后

1、可以使用cnpm install 安裝使用phantomjs的項(xiàng)目的node_modules，cnpm 會(huì) 使用phantomjs-prebuilt代替phantomjs，并且不中途翻車

2、下載安裝phantomjs，并配置環(huán)境變量，這樣不管是cnpm install還是npm install都可以使用phantomjs，而且在pycharm里面也不會(huì)報(bào)找不到phantomjs的錯(cuò)誤
