psql export return 当文件存在时没有那个文件或目录

Question

我运行

psql -E -U siteportal -d portal -h 172.19.242.32 -c "COPY externals (id,logo_path,favicon_path,cover_path,header,description,sign_enable,sign_text,footer_logo_enable,footer_logo_path,footer_text,created_at,updated_at) FROM '/Applications/MAMP/htdocs/code/site/portal/public/csv/externals.csv' DELIMITER ',' csv;"

我得到了

ERROR:  could not open file "/Applications/MAMP/htdocs/code/site/portal/public/csv/externals.csv" for reading: No such file or directory

但我确定文件在那里，因为当我运行

cat /Applications/MAMP/htdocs/code/site/portal/public/csv/externals.csv

我得到了

1,"/images/account/operator/logo.png","/images/account/operator/favicon.png","/images/account/operator/external.png","site Portal","Log in using your credentials",1,"This is a secure page",1,"/images/account/operator/footer_logo.png","© 2017 site Networks Inc.","2016-12-22 13:37:42","2017-01-31 14:22:11"

是不是权限问题？

-rwxrwxrwx@ 1 site  staff    307 May 24 13:46 externals.csv

我什至尝试 chomd 777 和运行与 sudo。但似乎没有任何帮助！

将 copy 更改为 \copy (https://www.postgresql.org/docs/current/static/app-psql.html#APP-PSQL-META-COMMANDS-COPY)。稍微不同的命令可让您将 to/from 文件复制到您的服务器。

此处不同的原因是因为您正在连接到远程服务器（我假设），但导入的是本地文件。

另一种选择是传递您的文件并让 psql 从标准输入中读取

 -c "copy externals (id,logo_path,favicon_path,cover_path,header,description,sign_enable,sign_text,footer_logo_enable,footer_logo_path,footer_text,created_at,updated_at) from STDIN with delimiter as ','" < /Applications/MAMP/htdocs/code/benu/ssc-portal/public/csv/externals.csv
