我最近迁移到了Py 3.5.这段代码在Python 2.7中正常工作:
with open(fname, 'rb') as f:
lines = [x.strip() for x in f.readlines()]
for line in lines:
tmp = line.strip().lower()
if 'some-pattern' in tmp: continue
# ... code
升级到3.5后,我得到了:
TypeError: a bytes-like object is required, not 'str'
最后一行的错误(模式搜索代码).
我已尝试.decode()在语句的任何一侧使用该函数,也尝试过:
if tmp.find('some-pattern') != -1: continue
- 无济于事.
我能够迅速解决几乎所有2:3的问题,但这个小小的陈述让我烦恼.
我conda install -c acellera pyinstaller=3.2.3按照Anaconda的网站做了,看起来它安装正确,但如果我尝试通过cmd运行它,我得到以下内容:

当我运行此命令时：pyinstaller gui.py
