用conda安装它。对我很有效！

conda install -c conda-forge textblob

试试这个：

from textblob import TextBlob

来源：TextBlob package description

在Windows中，如果您尝试在python中安装textblob或任何其他软件包，则必须向安装软件包的应用程序给予管理权限。
对我来说，当我通过Pycharms安装它时，它给出了同样的错误。我给了管理权，它工作得很好！

pip install -U textblob
python -m textblob.download_corpora

要导入，只需输入：

from textblob import TextBlob

示例：

text = '''
The titular threat of The Blob has always struck me as the ultimate movie
monster: an insatiably hungry, amoeba-like mass able to penetrate
virtually any safeguard, capable of--as a doomed doctor chillingly
describes it--"assimilating flesh on contact.
Snide comparisons to gelatin be damned, it's a concept with the most
devastating of potential consequences, not unlike the grey goo scenario
proposed by technological theorists fearful of
artificial intelligence run rampant.
'''

blob = TextBlob(text)
blob.tags           # [('The', 'DT'), ('titular', 'JJ'),
                    #  ('threat', 'NN'), ('of', 'IN'), ...]

blob.noun_phrases   # WordList(['titular threat', 'blob',
                    #            'ultimate movie monster',
                    #            'amoeba-like mass', ...])

for sentence in blob.sentences:
    print(sentence.sentiment.polarity)
# 0.060
# -0.341

blob.translate(to="es")  # 'La amenaza titular de The Blob...'

尝试

pip install textblob

如果你没有pip，你可以得到它here，这是非常有用

conda install -c conda-forge textblob

这是在一个环境下工作的。
