1. Move the mouse to the input label, prompt: Please enter a valid value, and the two closest valid values are x and x respectively.
Reason: When the type attribute of the input is number, the value in the input box is a decimal, and this problem occurs.
Solution: <input type="number" min="-999999999" max="9999999999" step="0.0000001" />
2. There are more unexpected blank nodes in the dom node
Reason: This is because there is a gap between the node and the node (it may be caused by copying the text first and then adding the label)
Solution: Delete the newline of the label, and then manually enter the newline.
3. Install backstop ( npm install -g backstopjs ) and report an error:
content:
ERROR: Failed to download Chromium r722234! Set "PUPPETEER_SKIP_CHROMIUM_DOWNLOAD" env variable to skip download.
Reason: This is because of some PATH variable problems reported when installing the headless browser.
Solution: sudo npm install -g backstopjs --unsafe-perm=true --allow-root
4. Install the vscode plugin -----background, and vscode reports software damage.
Content: The code installation seems to be damaged, please reinstall
