我正在尝试启动一个React Native应用程序。但是当我这样做时，出现错误interaction_strength_art <- NULL
for (j in 1:10)
{
print(j)
interaction_strength_art <- c(interaction_strength_art, step_2_to_4())
}
summary(interaction_strength_art)
# Min. 1st Qu. Median Mean 3rd Qu. Max.
#-0.052648 -0.019415 0.001124 -0.004310 0.012759 0.042058

文件：
gradle-wrapper.properties该如何解决此错误？
UPD。通过启用我居住在克里米亚的VPN原因解决了该问题。
答案 0 :(得分：0)
在google块中添加buildscript仓库：
buildscript {
//....
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.6.2'
//...
}
}
