任务:ReactAndroid:hermes-engine:configureBuildForHermes失败反应本机新架构版本0.69.1

Question

我在装配调试时遇到了问题。它可以工作几个点，但是在配置android的构建时失败了。

> Task :ReactAndroid:hermes-engine:configureBuildForHermes FAILED
CMake Deprecation Warning at CMakeLists.txt:42 (cmake_policy):
  The OLD behavior for policy CMP0026 will be removed from a future version
  of CMake.

  The cmake-policies(7) manual explains that the OLD behaviors of all
  policies are deprecated and that a policy should be set to OLD only under
  specific short-term circumstances.  Projects should be ported to the NEW
  behavior and not rely on setting a policy to OLD.

Answer 1

我终于找到了答案，基本上我使用的是Ubuntu20.04，而且我没有ICU组件，所以如果您使用的是Ubuntu，那么您必须通过以下方式安装icu组件

git clone https://github.com/unicode-org/icu
cd icu/icu4c
cd source
./configure --prefix=/usr 
make
sudo make install

那么您可能会遇到类似于Task :ReactAndroid:hermes-engine:buildCMakeRelease[arm64-v8a][libhermes] FAILED这样的问题。

目前还有一个与此相关的悬而未决的问题。请参阅前面的https://github.com/facebook/react-native/issues/34084

我也遇到了同样的问题，但是如果安装libicu-dev，我的os是mint 20.3 ubuntu基地20.04。

sudo apt -y libicu-dev

我的问题解决了
