ns create 无法创建工作项目

Question

我执行以下操作：

ns create HelloNg --template @nativescript/template-tab-navigation-ng
ns create BlankNg --template @nativescript/template-blank-ng
ns create Blank --template @nativescript/template-blank
ns create Create
# allways finished with:
Project xyz was successfully created.
# after change the working directory to the project folder, i try to run/debug
ns run android
ns debug android

我总是遇到同样的错误：Cannot read properties of null (reading 'forEach')

ns doctor android 输出为：未检测到任何问题。

系统：Ubuntu20.04

NativeScript 8.2.2

npm 8.3.1

节点 v16.14.0

我能做什么？

$ ns run android

现在 --log trace

$ ns debug android --log trace

Answer 1

Cannot read properties of null (reading 'forEach')

这个错误听起来像是来自您自己的代码。您在某处使用 forEach 并且对象为空。如果您在控制台日志中进一步查看，您可以看到准确的行号。

Answer 2

我发现了错误。 Node.js 作为 snap 包安装。这导致各种工具出现问题。

现在 Node.js 已从 node.tar.xz 安装到我的主目录中，一切正常。
