New submission from Valentin Zhao <[email protected]>:
I want to manage all the packages that I installed so every time adding package
I set "--target" so the package will be downloaded there. Then I wrote the
directory in a .pth file which is located in "/Python36/Lib/site-packages" so I
could still get accessed to all the packages even though they are not located
within "Python36" folder.
However, my current user name of Windows is a Chinese name, which means the
customized path I mentioned before has Chinese characters within it, thus the
.pth file will be also encoded with 'gbk'. Every time I would like to import
these packages will get "UnicodeDecodeError: 'gbk' can't decode byte xxx...".
Fortunately I have found the reason and cracked the problem: python read .pth
files without setting any encoding. The code is located in
"Python36/Lib/site.py"
def addpackage(sitedir, name, known_paths):
if known_paths is None:
known_paths = _init_pathinfo()
reset = True
else:
reset = False
fullname = os.path.join(sitedir, name)
try:
# here should set the second param as encoding='utf-8'
f = open(fullname, "r")
except OSError:
return
# other codes
And after I doing this, everything goes well.
