尝试在CLI中创建迁移时发生TypeORM错误

Question

我正在尝试使用TypeORM CLI创建迁移。我遵循了他们的指导，但当我运行yarn run typeorm migration:generate时，我得到了错误：

$ typeorm-ts-node-commonjs migration:generate
/usr/bin/env: ‘node --require ts-node/register’: No such file or directory
/usr/bin/env: use -[v]S to pass options in shebang lines
error Command failed with exit code 127.

我的包.json看起来像这样：

"name": "server",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo "Error: no test specified" && exit 1",

Answer 1

我按照这里的说明安装了cli，解决了这个问题https://orkhan.gitbook.io/typeorm/docs/using-cli#installing-cli

全局安装ts节点npm install -g ts-node

将以下脚本添加到package.json中："typeorm": "node --require ts-node/register ./node_modules/typeorm/cli.js"而不是"typeorm": "typeorm-ts-node-commonjs"

然后创建一个迁移：yarn run typeorm migration:generate -p -d src/data-source.ts src/migrations/<filename without ending>

仅供参考：对于任何面临类似问题的人：我花了一段时间才发现typeorm上的各种文档目前令人困惑和冲突，因为它们刚刚移动到v0.3.0，并不是所有内容都更新了。

您可以尝试使用此版本的脚本"typeorm": "ts-node -r tsconfig-paths/register ./node_modules/typeorm/cli.js"在我的情况下这个工作！
