ng new出現毛線失敗：找不到軟件包“ @ ngtools / webpack @ 1.10.2”

Question

我嘗試用ng-cli和yarn創建一個新的angular項目，但是找不到包@ ngtools / webpack。

我在github上創建了一個問題： https : //github.com/angular/angular-cli/issues/9992

這是命令的結果：

Error: Package install failed, see above.
Package install failed, see above.

但是可以在這里找到該軟件包： https : //www.npmjs.com/package/@ngtools/webpack

然后，我在目錄中再次嘗試，但再次失敗並出現另一個錯誤

$ cd angular5-toh
$ yarn
yarn install v1.5.1
info No lockfile found.
[1/4] Resolving packages...
error An unexpected error occurred: "Couldn't find package \"@schematics/angular@0.3.2\" required by \"@angular/cli@~1.7.3\" on the \"npm\" registry.".
info If you think this is a bug, please open a bug report with the information provided in "/home/.../angular5-toh/yarn-error.log".
info Visit https://yarnpkg.com/en/docs/cli/install for documentation about this command.

那么問題出在哪里呢？ 我怎樣才能解決這個問題 ？

我正在使用Archlinux，以下是這些版本：

$ ng version

    _                      _                 ____ _     ___
   / \   _ __   __ _ _   _| | __ _ _ __     / ___| |   |_ _|
  / △ \ | '_ \ / _` | | | | |/ _` | '__|   | |   | |    | |
 / ___ \| | | | (_| | |_| | | (_| | |      | |___| |___ | |
/_/   \_\_| |_|\__, |\__,_|_|\__,_|_|       \____|_____|___|
               |___/

Angular CLI: 1.7.3
Node: 9.8.0
OS: linux x64
Angular: 
...

$ yarn --version
1.5.1

謝謝

更新＃1：我進行了新的嘗試，並且錯誤有所不同。

更新＃2：我嘗試多次安裝yarn ，但出現了兩個錯誤之一。

$ yarn install
yarn install v1.5.1
info No lockfile found.

當然也沒有node_modules /目錄
