折騰：

后，在之前已經(jīng)用過PyCharm去加上斷點(diǎn)實(shí)時(shí)調(diào)試別的python程序的前提下。

下載希望可以用PyCharm也可以加斷點(diǎn)，實(shí)時(shí)調(diào)試scrapy的項(xiàng)目。

不過能想到的是，scrapy這種項(xiàng)目，應(yīng)該屬于稍微特殊點(diǎn)的，畢竟可能涉及到多線程同時(shí)運(yùn)行，以及在不同目錄下執(zhí)行scrapy還會(huì)有不同的命令(比如在項(xiàng)目根目錄下scrapy —help，才能看到crawl子命令)

不過在用PyCharm去調(diào)試Python的Scrapy之前，先去解決：

加上斷點(diǎn)：

接著去設(shè)置調(diào)試配置

點(diǎn)擊+

通過之前在命令行中可以正常運(yùn)行的命令：

所以去設(shè)置對(duì)應(yīng)的路徑和命令：

結(jié)果發(fā)現(xiàn)選擇目錄后，script path還是空的：

并沒有看到以為的：

script path自動(dòng)變?yōu)?#xff1a;/Users/crifan/dev/dev_root/company/naturling/projects/scrapy/cbeebies

-》好像是必須要指定py文件的

現(xiàn)在變成了：

命令行下面是：

在路徑：/Users/crifan/dev/dev_root/company/naturling/projects/scrapy/cbeebies

中執(zhí)行：scrapy crawl Cbeebies

并不是之前的普通的可以指定某個(gè)py文件作為入口的

不知道如何運(yùn)行了。

pycharm debug scrapy

scrapy其實(shí)是個(gè)py->找到對(duì)應(yīng)的cmdline.py的完整路徑，即可再去加上參數(shù)，運(yùn)行了

然后可以繼續(xù)去配置了：script path：/usr/local/lib/python2.7/site-packages/scrapy/cmdline.py

parameter： crawl Cbeebies

再去調(diào)試試試：

結(jié)果出錯(cuò)：

好像說是：沒有指定對(duì)應(yīng)的項(xiàng)目？

參考：

好像是需要設(shè)置：working directory的

去加上：

然后再去調(diào)試：

果然可以開始調(diào)試運(yùn)行了：

然后到斷點(diǎn)就停下來了：

效果真心好用啊。

接下來就可以繼續(xù)暢快的去調(diào)試了。

注：

另外可以參考：

去創(chuàng)建自己的scrapy的運(yùn)行腳本，利用cmdline去運(yùn)行，理論上應(yīng)該也是可以的。就不去試了。
