【pyinstaller】报错：Unable to find “nltk

有时候，我们在打包调用nltk库的应用时，会遇到如下的报错：

Unable to find "nltk_data" when adding binary and data files

解决方法：

修改hook-nltk.py文件，通常此文件位于Anaconda安装文件夹下的site-packages里，比如我的hook-nltk.py位于：D:anacondaLibsite-packagesPyInstallerhookshook-nltk.py

修改此文件，具体如下：

import nltk
from PyInstaller.utils.hooks import collect_data_files
 
# add datas for nltk
datas = collect_data_files('nltk', False)
 
# loop through the data directories and add them
# for p in nltk.data.path:
#     datas.append((p, "nltk_data"))
 
datas.append(("", "nltk_data"))
 
# nltk.chunk.named_entity should be included
hiddenimports = ["nltk.chunk.named_entity"]

把修改成自己电脑中nltk_data文件夹所在的路径，比如：我的nltk_data文件夹位于D:nltk_data，那么就修改成：

datas.append(("D:\nltk_data", "nltk_data"))

注意：用双斜杠表示文件夹的路径

修改后的hook-nltk.py文件内容如下：

import nltk
from PyInstaller.utils.hooks import collect_data_files
 
# add datas for nltk
datas = collect_data_files('nltk', False)
 
# loop through the data directories and add them
# for p in nltk.data.path:
#     datas.append((p, "nltk_data"))
 
datas.append(("D:\nltk_data", "nltk_data"))
 
# nltk.chunk.named_entity should be included
hiddenimports = ["nltk.chunk.named_entity"]

如果找不到nltk_data的文件夹，可采用如下方法：

from nltk import data
print(data.find('.'))
