[PYTHON] Erreur lors de l'installation de pandas_datareader

1. À propos de cet article

Lorsque j'ai installé la bibliothèque Python "pandasa_datareader" qui acquiert les données réelles des actions américaines, l'erreur suivante a été générée.

python

Contre-mesures libxml2-dev Installez libxslt1-dev. Après avoir installé libxml2-dev libxslt1-dev, pandas_datareader a été installé avec succès.

python

root@2a1627805ea9:/home# apt-get install libxml2-dev libxslt1-dev
