jinja2是python下的一个根据html模板，产生html文件的库。在jinja2官方文档中，推荐使用PackageLoader的方式，产生html文件，但是这个方式却与pyinstaller冲突，所以我们需要修改成FileSystemLoader的方式来解决打包文件的问题。
不兼容pyinstall的老代码（PackageLoader产生HTML文件）
#使用PackageLoader产生html文件
def create_defect_html(defectlist, fileds, reportname=None):
"""
create html defects report in "./reports" directory
:param defectlist:传入问题单列表
:param fileds:传入问题单关键字列表
:param reportname:传入报告文件名称，若有需要可以指定生成的html报告名称；若不传，则默认为DefectList.html
:return:无返回，在reports目录下生成html报告
"""
mycolumnlist = col_transform(fileds)
env = Environment(loader = PackageLoader('TAReport', 'templates'))
template = env.get_template('DefectTemplate.html')
if reportname:
filestr = './reports/' + reportname + '.html'
else:
filestr = './reports/DefectList.html'
with open(filestr, 'w+') as f:
f.write(str(template.render(defectlist=defectlist, columnlist=mycolumnlist)))
使用FileSystemLoader，能够正确使用pyinstaller打包的新代码
