Question

我最近将Angular CLI升级到7.2.1。升级后，我意识到在使用

创建新项目时

ng新的hello-ng-world

命令失败，并出现以下错误。

npm WARN deprecated circular-json@0.5.9: CircularJSON is in maintenance only, flatted is its successor.
npm ERR! Unexpected end of JSON input while parsing near '...ource-map":"0.1.x"},"'

npm ERR! A complete log of this run can be found in:
npm ERR!     C:\Users\XXX\AppData\Roaming\npm-cache\_logs\2019-01-15T04_01_29_782Z-debug.log
Package install failed, see above.

我检查了日志文件，发现以下几行

2298 silly fetchPackageMetaData error for mini-css-extract-plugin@0.4.4 Unexpected end of JSON input while parsing near '...","webpack-cli":"^2.0'
....
2316 silly fetchPackageMetaData error for portfinder@1.0.17 Unexpected end of JSON input while parsing near '...82V3Kq5OEdhCZQ8nOUUQ/'

无法继续创建项目。请建议可以做什么。

我不得不强制清除缓存以使其正常运行。我使用了以下命令。

import os
import sys
sys.path.insert(0, os.path.dirname(__file__))

wsgi = imp.load_source('wsgi', 'aida_ganaderia_luz_y_sombra/wsgi.py')
application = wsgi.application
