[Python知识库]安装nlgeval报错

结论放在前面：
换网络，或是科学上网，或是重启wifi，不断尝试以下代码：

python setup.py install

wish you lucky~

以下是错误到成功过程：

按照https://blog.csdn.net/qq_38247544/article/details/106650471安装，报错如下

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
nlg-eval 2.3 requires Cython>=0.28.5, which is not installed.
nlg-eval 2.3 requires gensim~=3.8.3, which is not installed.
nlg-eval 2.3 requires nltk>=3.4.5, which is not installed.
