[英]Module parse failed: Unexpected token (257:106) You may need an appropriate loader to handle this file type
在我的应用程序上运行“npm update”后,我突然收到以下错误:
Compiled with problems:
ERROR in ./node_modules/pako/lib/zlib/trees.js 257:106
Module parse failed: Unexpected token (257:106)
File was processed with these loaders:
* ./node_modules/babel-loader/lib/index.js
You may need an additional loader to handle the result of these loaders.
| * not null.
| */
> function gen_bitlen(s, desc) /* deflate_state *s;*/ /* tree_desc *desc; /* the tree descriptor */*/{
| var tree = desc.dyn_tree;
| var max_code = desc.max_code;
奇怪的。 因此,我将它与在不同工作站上运行的具有相同代码但未运行“npm update”的相同应用程序进行了比较。 该应用程序有效,不足为奇。
我看过其他有此错误的帖子,但他们的解决方案似乎不适用于我的环境。
我不明白为什么它不能在我的主工作站上运行。 如果我从工作站复制 node_modules,应用程序可以正常启动。 但是,一旦我删除 node_modules 和 package-lock.json 并重新安装,该应用程序将无法启动。 我删除了 node_modules/package-lock.json/clear npm 缓存。 没有帮助。
我正在通过“npm ls”比较模块版本,它们在两个工作站上是相同的。
两者都在运行 NodeJS 8.12.0 和 npm 8.19.2
我查看了它出错的文件 (pako/lib/zlib/trees.js),它在两个系统上是相同的。
我不知道“pako”是什么,但使用“npm explain pako”它似乎与 pdf-lib 有关,它从未更新过。
我的应用程序是用 create-react-app 构建的。
我完全不知所措。 这是我的package.json

我做了一个解决方法。 我比较了我项目的新旧package-lock.json
,我看到一些 @babel lib 版本更改为 v7.20.2( 2022 年 11 月 4 日)。 我用旧的覆盖了新的package-lock.json
,我的 React 应用程序再次构建并成功运行。
然后我在我的 package.json 中更改(降级)一些@babel package.json
并解决了问题:
将此行放入您的package.json
文件中:
"@babel/core": "7.19.6",
"@babel/generator": "7.19.6",
"@babel/compat-data": "7.19.4",
"@babel/helper-compilation-targets": "7.19.3",
"@babel/helper-create-class-features-plugin":"7.19.0",
"@babel/helper-module-transforms":"7.19.6",
https://github.com/babel/babel/issues/15132
Babel 解决了他们的问题。 您可以使用最新版本,它现在应该可以使用了。 (我验证过了)
扩展@Attila Szombathelyi 的回答,如果您使用的是 CRA,则可以使用package.json
中的分辨率
{
"name": "app-name",
"version": "1.0.0",
"dependencies": {
...
},
...
"resolutions": {
"@babel/core": "7.19.6",
"@babel/generator": "7.19.6",
"@babel/compat-data": "7.19.4",
"@babel/helper-compilation-targets": "7.19.3",
"@babel/helper-create-class-features-plugin": "7.19.0",
"@babel/helper-module-transforms": "7.19.6",
"babel-loader": "8.2.5"
}
}
在我的案例中,解决方案是禁用 babel 依赖项转换(在我们的项目中启用)。
我是怎么做到的? 在我的项目中使用了 vue-cli。 所以我在vue.config.js
中禁用了transpileDependecies
选项
如果您使用的是裸机 webpack,您也可以为它或任何其他构建系统找到合适的解决方案。
解决方法:从 npm 8.3.0 开始,您还可以在 package.json 中使用 npm 的覆盖。 删除 package-lock.json 和 node_modules 文件夹(推荐)。

"@babel/core": "7.19.6",
