Question

我正在运行./node_modules/.bin/knex migrate:latest --env local

这将导致以下错误：

> knex migrate:latest --env local

Requiring external module ts-node/register
Using environment: local
TimeoutError: Knex: Timeout acquiring a connection. The pool is probably full. Are you missing a .transacting(trx) call?

我什至尝试删除数据库并重新运行。

我需要以某种方式清除连接吗？我的应用程序未运行。

使用以下内容

"knex": "0.19.0",

节点-v：v14.0.0

psql (PostgreSQL) 11.7

Answer 1

通过简单地降级到节点版本13.11.0来解决此问题：

sudo npm install -g n
sudo n 13.11.0
knex migrate:latest
#  Requiring external module ts-node/register
#  Using environment: local
#  Batch 1 run: 63 migrations

是的

Answer 2

Knex: Timeout acquiring a connection. The pool is probably full...

升级pg@8.3.0解决了该问题。
环境：
节点14.6
pg：7.8
“ knex”：“ ^ 0.20.10”，
