${ERROR_PAD}Seems like you have internet connection issues.
${ERROR_PAD}Try running the same command again.
${ERROR_PAD}If that doesn't help, try one of the following:
${ERROR_PAD}
${ERROR_PAD}- Set a bigger value for the \`fetch-retries\` config.
${ERROR_PAD}    To check the current value of \`fetch-retries\`, run \`pnpm get fetch-retries\`.
${ERROR_PAD}    To set a new value, run \`pnpm set fetch-retries <number>\`.
${ERROR_PAD}
${ERROR_PAD}- Set \`network-concurrency\` to 1.
${ERROR_PAD}    This change will slow down installation times, so it is recommended to
${ERROR_PAD}    delete the config once the internet connection is good again: \`pnpm config delete network-concurrency\`
${ERROR_PAD}
${ERROR_PAD}NOTE: You may also override configs via flags.
${ERROR_PAD}For instance, \`pnpm install --fetch-retries 5 --network-concurrency 1\``)
