_load_jestResolve(...)).default.findNodeModule：(TypeError || _jestResolve不是函数

Question

我有一个项目是用Webpack 4和巴别塔6建立的，我想升级到巴别塔7。我安装了以下软件包：

+    "@babel/cli": "^7.2.3",
+    "@babel/core": "^7.2.2",
+    "@babel/plugin-syntax-dynamic-import": "^7.2.0",
+    "@babel/preset-env": "^7.2.3",
+    "@babel/preset-flow": "^7.0.0",
+    "@babel/preset-react": "^7.0.0",
+    "babel-loader": "^8.0.5",
+    "css-loader": "^2.1.0",

..。并去掉了旧的：

-    "babel-core": "^6.26.0",
-    "babel-loader": "^6.4.1",
-    "babel-plugin-react": "^1.0.0",
-    "babel-plugin-transform-es2015-destructuring": "^6.23.0",
-    "babel-plugin-transform-object-rest-spread": "^6.26.0",
-    "babel-plugin-transform-runtime": "^6.23.0",
-    "babel-polyfill": "^6.26.0",
-    "babel-preset-es2015": "^6.24.1",
-    "babel-preset-react": "^6.24.1",
-    "babel-preset-stage-0": "^6.24.1",
-    "css-loader": "^0.28.9",

但是现在，每当我运行Jest时，我都会收到这个错误...

TypeError: (_jestResolve || _load_jestResolve(...)).default.findNodeModule is not a function

事实证明，我所需要的就是安装"babel-core": "^7.0.0-bridge.0"。

最后，我使用的是babel-upgrade，它安装了包括桥在内的所有缺少的软件包。
