Answer 1

听起来像缺少依赖项。尝试删除node_modules并再次运行npm install。

Answer 2

我遇到了同样的问题，我错误地在系统根目录中运行了单元。一旦我删除了所有的angular-cli文件就可以了

我在windows-10系统上做了什么来解决。

打开cmd。
运行目录。（在Linux或Mac中它的ls）。
如果您发现 angular-cli 文件，只需删除。

它对我有用。

Answer 3

这适用于1.3.1。我还将包中的dev从angular/cli 131更改为angular cli 1.7.4（可能是可选的）

验证您是否拥有该目录（ubuntu上为chown groupe:user directory）并尝试为ng（sudo）启动根目录

或/并删除节点目录和-lock.json，运行npm i并启动或sudo launch ng

Answer 4

我现在知道你需要拥有该目录的权利，以免出现sudo和安装权限问题。你不会需要sudo。再看看npm update。

chown user：user / directory - ＆gt; 4 ubuntu

Angular-cli ng不起作用
