我使用Bottle框架创建了一个小型Web服务器来提供一个网页。这是通过我的python脚本“hello.py”完成的。从“hello.py”生成的网页，我可以编辑名为“data.txt”的文件的内容。当我从终端（python hello.py）运行“hello.py”时，这一切都很好。
但是当我使用PyInstaller创建可执行文件时遇到了问题。 我无法写入我的“data.txt”文件。我得到的错误消息是“权限被拒绝”。除此之外，可执行文件中的其他所有内容都可以使用！
在创建可执行文件之前，我将“data.txt”权限设置为777.这没有帮助。我也试过一个我在这里找到的潜在解决方案 - 但没有运气。它看起来像这样：
def resource_path(relative_path):
""" Get absolute path to resource, works for dev and for PyInstaller """
try:
# PyInstaller creates a temp folder and stores path in _MEIPASS
base_path = sys._MEIPASS
except Exception:
base_path = os.path.abspath(".")
return os.path.join(base_path, relative_path)
def fix_ownership(path):
"""Change the owner of the file to SUDO_UID"""
uid = os.environ.get('SUDO_UID')
gid = os.environ.get('SUDO_GID')
if uid is not None:
os.chown(resource_path(path), int(uid), int(gid))
@post('/data<dataValue>') # or @route('/login')
def data(dataValue):
thePostRequest = str(request.query_string)
newPostRequest = string.replace(thePostRequest, '%22', '\"')
fix_ownership("data.txt")
with open("data.txt","w") as fo:
fo.write('data = '+newPostRequest)
return
我寄予厚望，但那也没有用。这是我现在的代码（我是Python的新手，所以让我知道任何明显的错误）：

答案 0 :(得分：1)
我明白了！首先，我必须参考我的＆＃34; data.txt＆＃34;使用此功能的文件：
def resource_path(relative_path):
""" Get absolute path to resource, works for dev and for PyInstaller """
try:
# PyInstaller creates a temp folder and stores path in _MEIPASS
base_path = sys._MEIPASS
except Exception:
base_path = os.path.abspath(".")
return os.path.join(base_path, relative_path)
我这样使用它：
theDataFile = resource_path('./data.txt')
然后当我去写我的文件时，它工作了！像这样：
def data(dataValue):
thePostRequest = str(request.query_string)
newPostRequest = string.replace(thePostRequest, '%22', '\"')
newPostRequest = newPostRequest.replace('%27', '\'')
newPostRequest = newPostRequest.replace('%20', ' ')
newPostRequest = newPostRequest.replace('%7B', '{')
newPostRequest = newPostRequest.replace('%7D', '}')
print "This is the data value: " + newPostRequest
theDataFile = resource_path('./data.txt')
with open(theDataFile,"w") as fo:
fo.write('data = '+newPostRequest)
return
