Erro no import dos dados xlsv

Estou com o seguinte código:

df_excel = pd.read_excel('dados/aluguel.xlsx')
df_excel

E com esse erro gigante:

ModuleNotFoundError                       Traceback (most recent call last)

    262         except ImportError:

ModuleNotFoundError: No module named 'xlrd'

During handling of the above exception, another exception occurred:

ImportError: Install xlrd >= 0.9.0 for Excel support

Porém já realizei a instalação desses arquivos no prompt do anaconda: conda install -c anaconda xlrd

conda install -c anaconda lxml

conda install -c anaconda html5lib

conda install -c anaconda beautifulsoup4

E também surgiu esse erro:

    698     return _valid_parsers[flavor]
    699 

ImportError: lxml not found, please install it

Porém aparentemente o resto está correto.
