Question

尝试在angular cli中创建库时出现以下错误

Schematic "library" not found in collection "@schematics/angular".
Error: Schematic "library" not found in collection

命令ng --version

显示了这个

Angular CLI: 1.7.4
Node: 8.9.3
OS: linux x64
Angular: 


node -v
v8.9.3

npm -v
5.5.1

Answer 1

npm i -g @angular/cli

将您更新为最新版本的原理图。更新角度cli也很重要：

#include <iostream>
#include <string>
#include <algorithm>
#include <iterator>

template<class Haystack, class Needle, class OutputIterator>
void separate(Haystack&& haystack, Needle&& needle, OutputIterator output_iter)
{
    const char* sep = "";

    auto first = std::begin(haystack);
    auto last = std::end(haystack);

    auto first_needle = std::begin(needle);
    auto last_needle = std::end(needle);
    auto needle_length = std::distance(first_needle, last_needle);

    while (first != last)
    {
        auto next = std::search(first, last, first_needle, last_needle);

        if (next == first)
        {
            first = std::next(first, needle_length);
        }
        else
        {
            std::cout << sep;
            std::copy(first, next, output_iter);
            sep = " ";
            first = next;
        }
    }
}

int main()
{
    using namespace std::literals;

    const auto needle = "FOO"s;

    const auto haystack = "FOOTHEFOOFOOBEST"s;

    separate(haystack, needle, std::ostream_iterator<char>(std::cout, ""));

    return 0;
}

Answer 2

图书馆支持从Angular cli版本6＆amp;以上...

请查看release note以获取更多信息......

Answer 3

这对我有用：

npm i @schematics/angular

Answer 4

ng config cli.defaultCollection @ ngrx / schematics

原理图＆＃34;库＆＃34;没有在集合中找到＆＃34; @ schematics / angular＆＃34;
