未定义不是对象(评估 'Sn[e]') [英] Undefined is not an object (evaluating 'Sn[e]')
问题描述
我在 Android 上收到此错误:
I'm getting this error on Android:
我在'index.android.bundle'中找到了代码行'Sn[e]'
,我粘贴在下面(ctrl/command + F):
I have found that line of code 'Sn[e]'
in 'index.android.bundle' which I have pasted below (ctrl/command + F):
for (var An in Sn) xn[An] = Sn[An];
for (var Dn in wn) Pt(!Sn[Dn], "Event cannot be both direct and bubbling: %s", Dn), xn[Dn] = wn[Dn];
var kn = {
eventTypes: En({}, Sn, wn),
extractEvents: function(e, t, n, o) {
var r = Sn[e],
i = wn[e],
a = Pn.getPooled(r || i, t, n, o);
if (r) fn.accumulateTwoPhaseDispatches(a);
else {
if (!i) return null;
fn.accumulateDirectDispatches(a)
}
return a
}
},
jn = kn,
On = {
handleTopLevel: function(e, t, n, o) {
G(sn.extractEvents(e, t, n, o))
}
},
Mn = On,
Hn = 1,
Un = {
tagsStartAt: Hn,
tagCount: Hn,
allocateTag: function() {
for (; this.reactTagIsNativeTopRootID(Un.tagCount);) Un.tagCount++;
var e = Un.tagCount;
return Un.tagCount++, e
},
assertRootTag: function(e) {
It(this.reactTagIsNativeTopRootID(e), "Expect a native root tag, instead got %s", e)
},
reactTagIsNativeTopRootID: function(e) {
return e % 10 == 1
}
},
Fn = Un,
Wn = null,
Ln = {
injectFiberControlledHostComponent: function(e) {
Wn = e
}
},
Bn = null,
Yn = null,
Vn = {
injection: Ln,
enqueueStateRestore: function(e) {
Bn ? Yn ? Yn.push(e) : Yn = [e] : Bn = e
},
看起来像一段 React 代码,因为它有 injectFiberControlledHostComponent
看起来像 React Native Fiber.知道如何解决这个问题吗?
Looks like a React piece of code because it has injectFiberControlledHostComponent
which seems like React Native Fiber. Any idea how I can fix this?
我在 android studio 中启动了应用程序并且没有错误,因为应用程序构建和安装正常.我确实在 android studio gradle 控制台中看到过这个,但这可能不是问题:
I started the app in android studio and no errors because the app builds and installs fine. I did see this in the android studio gradle console but it's probably not the issue:

推荐答案
我遇到了同样的问题并通过将 app/build.gradle
更改为:
I faced the same problem and fixed by changing app/build.gradle
as:
编译com.facebook.react:react-native:+"
到
compile ("com.facebook.react:react-native:+") {力 = 真;}
另见:https://github.com/facebook/react-native/issues/17840
