我最近升级了我的Flutter,以前它在每个软件包中都可以正常工作,但是现在由于我的项目未运行,现在有件事困扰着我。这是名为PURE_MIXPANEL的软件包的cos错误。
错误:
The current Dart SDK version is 2.3.1-dev.0.0.flutter-a0290f823c.
Because pure_mixpanel 1.0.7 requires SDK version >=1.19.0 <=2.2.1 and no versions of pure_mi
xpanel match >1.0.7 <2.0.0, pure_mixpanel ^1.0.7 is forbidden.
So, because flutter_app depends on pure_mixpanel ^1.0.7, version solving failed.
Running "flutter packages get" in flutter_app...
pub get failed (1)
在互联网上,我关注了很多类似的事情:
因此它成功地升级了我的抖动,但提出了一个问题,即该软件包完全不受支持,但以前可以运行。
这是我的flutter doctor -v
结果:

您的SDK版本为2.3.1,pure_mixpanel的SDK为np.random.seed(0)
df = pd.DataFrame({'label': np.random.choice([-1,0,1], size=1000, replace=True),
'year_of_experience': np.random.randint(0,10, 1000)})
