找不到纱线文件

Question

我安装了yarn，但是当我尝试使用它时，出现以下问题：

fangio@fangio-UX305LA:~/Documents/UGent/Master2/S2/2_Datavisualisatie/datavis-project$ sudo npm install -g yarn
/usr/local/bin/yarnpkg -> /usr/local/lib/node_modules/yarn/bin/yarn.js
/usr/local/bin/yarn -> /usr/local/lib/node_modules/yarn/bin/yarn.js
/usr/local/lib
└── yarn@1.15.2 

fangio@fangio-UX305LA:~/Documents/UGent/Master2/S2/2_Datavisualisatie/datavis-project$ yarn install
bash: /usr/bin/yarn: No such file or directory

有人知道我做错了吗？
