Migration from lodash 3 to lodash 4: what replaces the 'lodash/string/template'?
问题
我们尝试将一个Backbone.js项目从lodash "3.10.1"迁移到最新的lodash "4.17.21"，似乎'lodash/string/template'在版本4中已被移除。
在我们的代码中，有类似这样的内容：
import template from 'lodash/string/template';
export default _.extend(window.app, {
...
template: (path, options) => template(someCustomMethod(path), options),
...
使用lodash 4安装后，捆绑程序崩溃并显示以下错误：
Error: Can't walk dependency graph: Cannot find module 'lodash/string/template'...
如果我以这种方式导入它：
import { template } from 'lodash';
然后编译通过，但当尝试加载应用程序时，会发生错误：
...Uncaught TypeError: Cannot set properties of undefined (setting '_url_prefix')
这来自于"Backbone.View"内部，似乎与lodash模板相关。
是否有人遇到过这样的问题？Backbone.js版本为1.1.2，但我认为与此无关 - 如果我回到lodash "3.10.1"，一切都运行正常。也许新的lodash模板版本返回了不同结构的结果？
英文:
We try to migrate one Backbone.js project from lodash "3.10.1" to latest lodash "4.17.21" and seems like 'lodash/string/template' was removed in version 4.
In our code we have something like:
import template from 'lodash/string/template';
export default _.extend(window.app, {
...
template: (path, options) => template(someCustomMethod(path), options),
...
And with lodash 4 installed the bundler crashes with:
Error: Can't walk dependency graph: Cannot find module 'lodash/string/template'...
In case I import it this way:
import { template } from 'lodash';
Then compilation passes but when you try to load the app then an error occurs:
...Uncaught TypeError: Cannot set properties of undefined (setting '_url_prefix')
It comes from inside "Backbone.View" and seems related to lodash template.
Have someone stumbled upon such an issue? The Backbone.js version is 1.1.2, but I think it's not related - if I return back to lodash "3.10.1" then all works perfectly. Maybe the new lodash template version returns differently structured results?

得分: 1
听起来你想要
import template from 'lodash/template';
至于 _url_prefix 错误，没有完整的堆栈跟踪无法提供更多信息。
英文:
It sounds like you want
import template from 'lodash/template';
and for the _url_prefix error it's impossible to say more without the full stack trace.
