PackagesNotFoundError:当前频道中没有下列程序包

Question

我试图在python中安装ngram，但它给出了错误。我试过这些代码，但所有的代码都给出了相同的错误：

conda install ngram

第二：

conda config --add channels loopbio
conda config --append channels conda-forge
conda install ngram -c conda-forge

错误是：

Solving environment: failed

PackagesNotFoundError: The following packages are not available from current channels:

  - ngram

我该怎么解决？

我也试过了

pip install ngram

Searching on anaconda.org显示此包不在您搜索的任何频道中。ngram包的pypi page表明它与Python 2.6、2.7和3.2兼容。如果您使用的是Python 3，那么您可能使用的是3.5或3.6这样的更新版本，而这个包似乎不支持这个版本。您可以从github下载并运行python setup.py install，尝试从源代码安装它。
