Rstudio Cloud 无法读取本地文件怎么处理

img


读取本地文件一直报错,任何文件都显示路径有问题,应该怎么解决?

Error in read_fst(path, columns, from, to, as.data.table,
old_format): 
There was an error opening the file, it seems to be incomplete or
damaged.
read_fst(路径,列,从,到,as.data.table,
旧格式):
打开文件时出错,文件似乎不完整或损坏

Error in read_fst(path, columns, from, to, as.data.table,
old_format):
Error opening fst file for reading, please check access rights and file
availability
read_fst(路径,列,从,到,as.data.table,
旧格式):
打开fst文件进行读取时出错,请检查访问权限和文件,可利用性

这2个报错明面上提示你:看一个文件是否可打开正常,在软件中打开是否给与权限
