Question

如Unable to resolve module `@babel/runtime/helpers/interopRequireDefault`中所述，我遇到了相同的错误，该问题的解决方案无法解决我的问题。

React Native - Unable to resolve module `@babel/runtime/helpers/interopRequireDefault`都无法解决我的问题。

我正在使用

R_peak = False   
j = 0
k = 0
idx_rr = []
sig = []

for i in range (len(sig_txt)):
    if (sig_txt[i] == 32767):
        idx_rr = i+1
        idx_rr[j] = np.array(sig_txt[i+1])
        sig = i+1
        sig[k] = np.array(sig_txt[i+1])
        k = k + 1
        j = j + 1
        print(idx_rr)
        R_peak = True
    else:
        if (R_peak == False):
            sig = i
            sig[k] = np.array(sig_txt[i])
            k = k + 1

        else:
            R_peak = False

plt.figure(figsize=(20,8))
plt.plot(sig)
plt.scatter([idx_rr], [sig[idx_rr]], c='g')  
plt.show()

该模块存在，我已经尝试了上述步骤，但仍然无法正常工作。该应用实际上通过消息error: bundling failed: Error: Unable to resolve module `@babel/runtime/helpers/interopRequireDefault` from `index.js`: @babel/runtime/helpers/interopRequireDefault could not be found within the project. If you are sure the module exists, try these steps: 1. Clear watchman watches: watchman watch-del-all 2. Delete node_modules: rm -rf node_modules and run yarn install 3.

在my case中，问题不是由RN引起的，而是由watchman引起的。

有两种方法可以解决此问题，直到修复潜在的错误为止：

首先要卸载watchman。

或手动编辑文件node_modules/jest-haste-map/build/index.js进行更改：

    const crawl =
      canUseWatchman && this._options.useWatchman
        ? _watchman.default
        : _node.default;

收件人：

    const crawl =
      canUseWatchman && this._options.useWatchman
        ? _node.default
        : _node.default;

后者当然不会在软件包升级中持续存在。
