使用npx cypress open
启动cypress 提示
No version of Cypress is installed in: /Users/xxx/Library/Caches/Cypress/13.3.3/Cypress.app
npx cypress open No version of Cypress is installed in: /Users/xxx/Library/Caches/Cypress/13.3.3/Cypress.app Please reinstall Cypress by running: cypress install ---------- Cypress executable not found at: /Users/xxx/Library/Caches/Cypress/13.3.3/Cypress.app/Contents/MacOS/Cypress ---------- Platform: darwin-x64 (19.6.0) Cypress Version: 13.3.3
如何解决呢：
这是因为安装的cypress包只是跑测试用例的代码, 而控制浏览器完成自动化测试的是通过Cypress应用程序进行的。
既然如此，我们就按照提示安装Cypress应用程序：
npx cypress install
结果发现根本装不下来，每次都是到1%的进度就断掉或者没有进展（
npx cypress install --force
本以为这样就ok 了但是又报错了
Error: EACCES: permission denied, mkdir '/Users/xxx/Library/Caches/Cypress/13.3.3'
npx cypress install --force Installing Cypress (version: 13.3.3) ✔ Downloaded Cypress The Cypress App could not be unzipped. Search for an existing issue or open a GitHub issue at https://github.com/cypress-io/cypress/issues ---------- Error: EACCES: permission denied, mkdir '/Users/xxx/Library/Caches/Cypress/13.3.3' ---------- Platform: darwin-x64 (19.6.0) Cypress Version: 13.3.3
于是使用超级管理员模式
sudo su Password: sh-3.2# npx cypress install --force Cypress 13.3.3 is installed in /var/root/Library/Caches/Cypress/13.3.3 Installing Cypress (version: 13.3.3) ✔ Downloaded Cypress ✔ Unzipped Cypress ✔ Finished Installation /var/root/Library/Caches/Cypress/13.3.3 You can now open Cypress by running: node_modules/.bin/cypress open https://on.cypress.io/installing-cypress
这下终于好了，看到了希望
使用命令
node_modules/.bin/cypress open
打开看到了久违的界面
